4.5.1 mysql — The MySQL Command-Line Tool
Chapter 3 Tutorial This chapter provides a tutorial introduction to MySQL by showing how to use the mysql client program to create and use a simple database. mysql (sometimes referred to as the “terminal monitor” or just “monitor”) is an interactive program that enables you to connect to a MySQL server, run queries, and view the results. mysql may also be used in batch mode: you place your queries in a file beforehand, then tell mysql to execute the contents of the file. Both ways of using mysql are covered here.

MYSQL(1) MySQL Database System MYSQL(1)
NAME
mysql - the MySQL command-line tool
SYNOPSIS
mysql [options] db_name
DESCRIPTION
mysql is a simple SQL shell with input line editing capabilities. It supports interactive and
noninteractive use. When used interactively, query results are presented in an ASCII-table format. When
used noninteractively (for example, as a filter), the result is presented in tab-separated format. The
output format can be changed using command options.
If you have problems due to insufficient memory for large result sets, use the --quick option. This
forces mysql to retrieve results from the server a row at a time rather than retrieving the entire result
set and buffering it in memory before displaying it. This is done by returning the result set using the
mysql_use_result() C API function in the client/server library rather than mysql_store_result().
Using mysql is very easy. Invoke it from the prompt of your command interpreter as follows:
shell> mysql db_name
Or:
shell> mysql --user=user_name --password=your_password db_name
Then type an SQL statement, end it with “;”, \g, or \G and press Enter.
Typing Control+C causes mysql to attempt to kill the current statement. If this cannot be done, or
Control+C is typed again before the statement is killed, mysql exits.
You can execute SQL statements in a script file (batch file) like this:
shell> mysql db_name < script.sql > output.tab
On Unix, the mysql client logs statements executed interactively to a history file. See the section
called “MYSQL LOGGING”.
MYSQL OPTIONS
mysql supports the following options, which can be specified on the command line or in the [mysql] and
[client] groups of an option file. For information about option files used by MySQL programs, see
Section 4.2.6, “Using Option Files”.
· --help, -?
Display a help message and exit.
· --auto-rehash
Enable automatic rehashing. This option is on by default, which enables database, table, and column
name completion. Use --disable-auto-rehash to disable rehashing. That causes mysql to start faster,
but you must issue the rehash command or its \# shortcut if you want to use name completion.
To complete a name, enter the first part and press Tab. If the name is unambiguous, mysql completes
it. Otherwise, you can press Tab again to see the possible names that begin with what you have typed
so far. Completion does not occur if there is no default database.
Note
This feature requires a MySQL client that is compiled with the readline library. Typically, the
readline library is not available on Windows.
· --auto-vertical-output
Cause result sets to be displayed vertically if they are too wide for the current window, and using
normal tabular format otherwise. (This applies to statements terminated by ; or \G.) This option was
added in MySQL 5.5.3.
· --batch, -B
Print results using tab as the column separator, with each row on a new line. With this option, mysql
does not use the history file.
Batch mode results in nontabular output format and escaping of special characters. Escaping may be
disabled by using raw mode; see the description for the --raw option.
· --bind-address=ip_address
On a computer having multiple network interfaces, use this option to select which interface to use
for connecting to the MySQL server.
This option is supported only in the version of the mysql client that is supplied with MySQL Cluster.
It is not available in standard MySQL Server 5.5 releases.
· --character-sets-dir=path
The directory where character sets are installed. See Section 10.5, “Character Set Configuration”.
· --column-names
Write column names in results.
· --column-type-info, -m
Display result set metadata.
· --comments, -c
Whether to preserve comments in statements sent to the server. The default is --skip-comments
(discard comments), enable with --comments (preserve comments).
· --compress, -C
Compress all information sent between the client and the server if both support compression.
· --database=db_name, -D db_name
The database to use. This is useful primarily in an option file.
· --debug[=debug_options], -# [debug_options]
Write a debugging log. A typical debug_options string is d:t:o,file_name. The default is
d:t:o,/tmp/mysql.trace.
· --debug-check
Print some debugging information when the program exits.
· --debug-info, -T
Print debugging information and memory and CPU usage statistics when the program exits.
· --default-auth=plugin
A hint about the client-side authentication plugin to use. See Section 6.3.6, “Pluggable
Authentication”.
This option was added in MySQL 5.5.7.
· --default-character-set=charset_name
Use charset_name as the default character set for the client and connection.
A common issue that can occur when the operating system uses utf8 or another multibyte character set
is that output from the mysql client is formatted incorrectly, due to the fact that the MySQL client
uses the latin1 character set by default. You can usually fix such issues by using this option to
force the client to use the system character set instead.
See Section 10.5, “Character Set Configuration”, for more information.
· --defaults-extra-file=file_name
Read this option file after the global option file but (on Unix) before the user option file. If the
file does not exist or is otherwise inaccessible, an error occurs. Before MySQL 5.5.8, file_name must
be the full path name to the file. As of MySQL 5.5.8, the name is interpreted relative to the current
directory if given as a relative path name.
· --defaults-file=file_name
Use only the given option file. If the file does not exist or is otherwise inaccessible, an error
occurs. Before MySQL 5.5.8, file_name must be the full path name to the file. As of MySQL 5.5.8, the
name is interpreted relative to the current directory if given as a relative path name.
· --defaults-group-suffix=str
Read not only the usual option groups, but also groups with the usual names and a suffix of str. For
example, mysql normally reads the [client] and [mysql] groups. If the --defaults-group-suffix=_other
option is given, mysql also reads the [client_other] and [mysql_other] groups.
· --delimiter=str
Set the statement delimiter. The default is the semicolon character (“;”).
· --disable-named-commands
Disable named commands. Use the \* form only, or use named commands only at the beginning of a line
ending with a semicolon (“;”). mysql starts with this option enabled by default. However, even with
this option, long-format commands still work from the first line. See the section called “MYSQL
COMMANDS”.
· --enable-cleartext-plugin
Enable the mysql_clear_password cleartext authentication plugin. (See Section 6.3.7.5, “The Cleartext
Client-Side Authentication Plugin”.) This option was added in MySQL 5.5.27.
· --execute=statement, -e statement
Execute the statement and quit. The default output format is like that produced with --batch. See
Section 4.2.4, “Using Options on the Command Line”, for some examples. With this option, mysql does
not use the history file.
· --force, -f
Continue even if an SQL error occurs.
· --host=host_name, -h host_name
Connect to the MySQL server on the given host.
· --html, -H
Produce HTML output.
· --ignore-spaces, -i
Ignore spaces after function names. The effect of this is described in the discussion for the
IGNORE_SPACE SQL mode (see Section 5.1.7, “Server SQL Modes”).
· --init-command=str
SQL statement to execute after connecting to the server. If auto-reconnect is enabled, the statement
is executed again after reconnection occurs.
· --line-numbers
Write line numbers for errors. Disable this with --skip-line-numbers.
· --local-infile[={0|1}]
Enable or disable LOCAL capability for LOAD DATA INFILE. With no value, the option enables LOCAL. The
option may be given as --local-infile=0 or --local-infile=1 to explicitly disable or enable LOCAL.
Enabling LOCAL has no effect if the server does not also support it.
· --named-commands, -G
Enable named mysql commands. Long-format commands are permitted, not just short-format commands. For
example, quit and \q both are recognized. Use --skip-named-commands to disable named commands. See
the section called “MYSQL COMMANDS”.
· --no-auto-rehash, -A
This has the same effect as --skip-auto-rehash. See the description for --auto-rehash.
· --no-beep, -b
Do not beep when errors occur.
· --no-defaults
Do not read any option files. If program startup fails due to reading unknown options from an option
file, --no-defaults can be used to prevent them from being read.
· --no-named-commands, -g
Deprecated, use --disable-named-commands instead. --no-named-commands was removed in MySQL 5.5.3.
· --no-pager
Deprecated form of --skip-pager. See the --pager option. --no-pager was removed in MySQL 5.5.3.
· --no-tee
Deprecated form of --skip-tee. See the --tee option. --no-tee is removed in MySQL 5.5.3.
· --one-database, -o
Ignore statements except those that occur while the default database is the one named on the command
line. This option is rudimentary and should be used with care. Statement filtering is based only on
USE statements.
Initially, mysql executes statements in the input because specifying a database db_name on the
command line is equivalent to inserting USE db_name at the beginning of the input. Then, for each USE
statement encountered, mysql accepts or rejects following statements depending on whether the
database named is the one on the command line. The content of the statements is immaterial.
Suppose that mysql is invoked to process this set of statements:
DELETE FROM db2.t2;
USE db2;
DROP TABLE db1.t1;
CREATE TABLE db1.t1 (i INT);
USE db1;
INSERT INTO t1 (i) VALUES(1);
CREATE TABLE db2.t1 (j INT);
If the command line is mysql --force --one-database db1, mysql handles the input as follows:
· The DELETE statement is executed because the default database is db1, even though the statement
names a table in a different database.
· The DROP TABLE and CREATE TABLE statements are not executed because the default database is not
db1, even though the statements name a table in db1.
· The INSERT and CREATE TABLE statements are executed because the default database is db1, even
though the CREATE TABLE statement names a table in a different database.
· --pager[=command]
Use the given command for paging query output. If the command is omitted, the default pager is the
value of your PAGER environment variable. Valid pagers are less, more, cat [> filename], and so
forth. This option works only on Unix and only in interactive mode. To disable paging, use
--skip-pager. the section called “MYSQL COMMANDS”, discusses output paging further.
· --password[=password], -p[password]
The password to use when connecting to the server. If you use the short option form (-p), you cannot
have a space between the option and the password. If you omit the password value following the
--password or -p option on the command line, mysql prompts for one.
Specifying a password on the command line should be considered insecure. See Section 6.1.2.1, “End-
User Guidelines for Password Security”. You can use an option file to avoid giving the password on
the command line.
· --pipe, -W
On Windows, connect to the server using a named pipe. This option applies only if the server supports
named-pipe connections.
· --plugin-dir=path
The directory in which to look for plugins. It may be necessary to specify this option if the
--default-auth option is used to specify an authentication plugin but mysql does not find it. See
Section 6.3.6, “Pluggable Authentication”.
This option was added in MySQL 5.5.7.
· --port=port_num, -P port_num
The TCP/IP port number to use for the connection.
· --print-defaults
Print the program name and all options that it gets from option files.
· --prompt=format_str
Set the prompt to the specified format. The default is mysql>. The special sequences that the prompt
can contain are described in the section called “MYSQL COMMANDS”.
· --protocol={TCP|SOCKET|PIPE|MEMORY}
The connection protocol to use for connecting to the server. It is useful when the other connection
parameters normally would cause a protocol to be used other than the one you want. For details on the
permissible values, see Section 4.2.2, “Connecting to the MySQL Server”.
· --quick, -q
Do not cache each query result, print each row as it is received. This may slow down the server if
the output is suspended. With this option, mysql does not use the history file.
· --raw, -r
For tabular output, the “boxing” around columns enables one column value to be distinguished from
another. For nontabular output (such as is produced in batch mode or when the --batch or --silent
option is given), special characters are escaped in the output so they can be identified easily.
Newline, tab, NUL, and backslash are written as \n, \t, \0, and \\. The --raw option disables this
character escaping.
The following example demonstrates tabular versus nontabular output and the use of raw mode to
disable escaping:
% mysql
mysql> SELECT CHAR(92);
+----------+
| CHAR(92) |
+----------+
| \ |
+----------+
% mysql -s
mysql> SELECT CHAR(92);
CHAR(92)
\\
% mysql -s -r
mysql> SELECT CHAR(92);
CHAR(92)
\
· --reconnect
If the connection to the server is lost, automatically try to reconnect. A single reconnect attempt
is made each time the connection is lost. To suppress reconnection behavior, use --skip-reconnect.
· --safe-updates, --i-am-a-dummy, -U
Permit only those UPDATE and DELETE statements that specify which rows to modify by using key values.
If you have set this option in an option file, you can override it by using --safe-updates on the
command line. See the section called “MYSQL TIPS”, for more information about this option.
· --secure-auth
Do not send passwords to the server in old (pre-4.1) format. This prevents connections except for
servers that use the newer password format.
Note
Passwords that use the pre-4.1 hashing method are less secure than passwords that use the native
password hashing method and should be avoided.
· --shared-memory-base-name=name
On Windows, the shared-memory name to use, for connections made using shared memory to a local
server. The default value is MYSQL. The shared-memory name is case sensitive.
The server must be started with the --shared-memory option to enable shared-memory connections.
· --show-warnings
Cause warnings to be shown after each statement if there are any. This option applies to interactive
and batch mode.
· --sigint-ignore
Ignore SIGINT signals (typically the result of typing Control+C).
· --silent, -s
Silent mode. Produce less output. This option can be given multiple times to produce less and less
output.
This option results in nontabular output format and escaping of special characters. Escaping may be
disabled by using raw mode; see the description for the --raw option.
· --skip-column-names, -N
Do not write column names in results.
· --skip-line-numbers, -L
Do not write line numbers for errors. Useful when you want to compare result files that include error
messages.
· --socket=path, -S path
For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named pipe
to use.
· --ssl*
Options that begin with --ssl specify whether to connect to the server using SSL and indicate where
to find SSL keys and certificates. See Section 6.3.9.4, “SSL Command Options”.
· --table, -t
Display output in table format. This is the default for interactive use, but can be used to produce
table output in batch mode.
· --tee=file_name
Append a copy of output to the given file. This option works only in interactive mode. the section
called “MYSQL COMMANDS”, discusses tee files further.
· --unbuffered, -n
Flush the buffer after each query.
· --user=user_name, -u user_name
The MySQL user name to use when connecting to the server.
· --verbose, -v
Verbose mode. Produce more output about what the program does. This option can be given multiple
times to produce more and more output. (For example, -v -v -v produces table output format even in
batch mode.)
· --version, -V
Display version information and exit.
· --vertical, -E
Print query output rows vertically (one line per column value). Without this option, you can specify
vertical output for individual statements by terminating them with \G.
· --wait, -w
If the connection cannot be established, wait and retry instead of aborting.
· --xml, -X
Produce XML output.
<field name="column_name">NULL</field>
The output when --xml is used with mysql matches that of mysqldump --xml. See mysqldump(1) for
details.
The XML output also uses an XML namespace, as shown here:
shell> mysql --xml -uroot -e "SHOW VARIABLES LIKE 'version%'"
<?xml version="1.0"?>
<resultset statement="SHOW VARIABLES LIKE 'version%'" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<row>
<field name="Variable_name">version</field>

(See Bug #25946.)
You can also set the following variables by using --var_name=value. The --set-variable format is
deprecated and was removed in MySQL 5.5.3.
· connect_timeout
The number of seconds before connection timeout. (Default value is 0.)

The automatic limit for SELECT statements when using --safe-updates. (Default value is 1,000.)
MYSQL COMMANDS
mysql sends each SQL statement that you issue to the server to be executed. There is also a set of
commands that mysql itself interprets. For a list of these commands, type help or \h at the mysql>
prompt:
mysql> help
List of all MySQL commands:
Note that all text commands must be first on line and end with ';'
? (\?) Synonym for `help'.
clear (\c) Clear command.
connect (\r) Reconnect to the server. Optional arguments are db and host.
delimiter (\d) Set statement delimiter.
edit (\e) Edit command with $EDITOR.
ego (\G) Send command to mysql server, display result vertically.
exit (\q) Exit mysql. Same as quit.
go (\g) Send command to mysql server.
help (\h) Display this help.
nopager (\n) Disable pager, print to stdout.
notee (\t) Don't write into outfile.
pager (\P) Set PAGER [to_pager]. Print the query results via PAGER.
print (\p) Print current command.
prompt (\R) Change your mysql prompt.
quit (\q) Quit mysql.
rehash (\#) Rebuild completion hash.
source (\.) Execute an SQL script file. Takes a file name as an argument.
status (\s) Get status information from the server.
system (\!) Execute a system shell command.
tee (\T) Set outfile [to_outfile]. Append everything into given
outfile.
use (\u) Use another database. Takes database name as argument.
charset (\C) Switch to another charset. Might be needed for processing
binlog with multi-byte charsets.
warnings (\W) Show warnings after every statement.
nowarning (\w) Don't show warnings after every statement.
For server side help, type 'help contents'
Each command has both a long and short form. The long form is not case sensitive; the short form is. The
long form can be followed by an optional semicolon terminator, but the short form should not.
The use of short-form commands within multi-line /* ... */ comments is not supported.
· help [arg], \h [arg], \? [arg], ? [arg]
Display a help message listing the available mysql commands.
If you provide an argument to the help command, mysql uses it as a search string to access
server-side help from the contents of the MySQL Reference Manual. For more information, see the
section called “MYSQL SERVER-SIDE HELP”.
· charset charset_name, \C charset_name
Change the default character set and issue a SET NAMES statement. This enables the character set to
remain synchronized on the client and server if mysql is run with auto-reconnect enabled (which is
not recommended), because the specified character set is used for reconnects.
· clear, \c
Clear the current input. Use this if you change your mind about executing the statement that you are
entering.
· connect [db_name host_name]], \r [db_name host_name]]
Reconnect to the server. The optional database name and host name arguments may be given to specify
the default database or the host where the server is running. If omitted, the current values are
used.
· delimiter str, \d str
Change the string that mysql interprets as the separator between SQL statements. The default is the
semicolon character (“;”).
The delimiter string can be specified as an unquoted or quoted argument on the delimiter command
line. Quoting can be done with either single quote ('), double quote ("), or backtick (`) characters.
To include a quote within a quoted string, either quote the string with a different quote character
or escape the quote with a backslash (“\”) character. Backslash should be avoided outside of quoted
strings because it is the escape character for MySQL. For an unquoted argument, the delimiter is read
up to the first space or end of line. For a quoted argument, the delimiter is read up to the matching
quote on the line.
mysql interprets instances of the delimiter string as a statement delimiter anywhere it occurs,
except within quoted strings. Be careful about defining a delimiter that might occur within other
words. For example, if you define the delimiter as X, you will be unable to use the word INDEX in
statements. mysql interprets this as INDE followed by the delimiter X.
When the delimiter recognized by mysql is set to something other than the default of “;”, instances
of that character are sent to the server without interpretation. However, the server itself still
interprets “;” as a statement delimiter and processes statements accordingly. This behavior on the
server side comes into play for multiple-statement execution (see Section 23.8.17, “C API Support for
Multiple Statement Execution”), and for parsing the body of stored procedures and functions,
triggers, and events (see Section 20.1, “Defining Stored Programs”).
· edit, \e
Edit the current input statement. mysql checks the values of the EDITOR and VISUAL environment
variables to determine which editor to use. The default editor is vi if neither variable is set.
The edit command works only in Unix.
· ego, \G
Send the current statement to the server to be executed and display the result using vertical format.
· exit, \q
Exit mysql.
· go, \g
Send the current statement to the server to be executed.
· nopager, \n
Disable output paging. See the description for pager.
The nopager command works only in Unix.
· notee, \t
Disable output copying to the tee file. See the description for tee.
· nowarning, \w
Disable display of warnings after each statement.
· pager [command], \P [command]
Enable output paging. By using the --pager option when you invoke mysql, it is possible to browse or
search query results in interactive mode with Unix programs such as less, more, or any other similar
program. If you specify no value for the option, mysql checks the value of the PAGER environment
variable and sets the pager to that. Pager functionality works only in interactive mode.
Output paging can be enabled interactively with the pager command and disabled with nopager. The
command takes an optional argument; if given, the paging program is set to that. With no argument,
the pager is set to the pager that was set on the command line, or stdout if no pager was specified.
Output paging works only in Unix because it uses the popen() function, which does not exist on
Windows. For Windows, the tee option can be used instead to save query output, although it is not as
convenient as pager for browsing output in some situations.
· print, \p
Print the current input statement without executing it.
· prompt [str], \R [str]
Reconfigure the mysql prompt to the given string. The special character sequences that can be used in
the prompt are described later in this section.
If you specify the prompt command with no argument, mysql resets the prompt to the default of mysql>.
· quit, \q
Exit mysql.
· rehash, \#
Rebuild the completion hash that enables database, table, and column name completion while you are
entering statements. (See the description for the --auto-rehash option.)
· source file_name, \. file_name
Read the named file and executes the statements contained therein. On Windows, you can specify path
name separators as / or \\.
· status, \s
Provide status information about the connection and the server you are using. If you are running in
--safe-updates mode, status also prints the values for the mysql variables that affect your queries.
· system command, \! command
Execute the given command using your default command interpreter.
The system command works only in Unix.
· tee [file_name], \T [file_name]
By using the --tee option when you invoke mysql, you can log statements and their output. All the
data displayed on the screen is appended into a given file. This can be very useful for debugging
purposes also. mysql flushes results to the file after each statement, just before it prints its
next prompt. Tee functionality works only in interactive mode.
You can enable this feature interactively with the tee command. Without a parameter, the previous
file is used. The tee file can be disabled with the notee command. Executing tee again re-enables
logging.
· use db_name, \u db_name
Use db_name as the default database.
· warnings, \W
Enable display of warnings after each statement (if there are any).
Here are a few tips about the pager command:
· You can use it to write to a file and the results go only to the file:
mysql> pager cat > /tmp/log.txt
You can also pass any options for the program that you want to use as your pager:
mysql> pager less -n -i -S
· In the preceding example, note the -S option. You may find it very useful for browsing wide query
results. Sometimes a very wide result set is difficult to read on the screen. The -S option to less
can make the result set much more readable because you can scroll it horizontally using the
left-arrow and right-arrow keys. You can also use -S interactively within less to switch the
horizontal-browse mode on and off. For more information, read the less manual page:
shell> man less
· The -F and -X options may be used with less to cause it to exit if output fits on one screen, which
is convenient when no scrolling is necessary:
mysql> pager less -n -i -S -F -X
· You can specify very complex pager commands for handling query output:
mysql> pager cat | tee /dr1/tmp/res.txt \
| tee /dr2/tmp/res2.txt | less -n -i -S
In this example, the command would send query results to two files in two different directories on
two different file systems mounted on /dr1 and /dr2, yet still display the results onscreen using
less.
You can also combine the tee and pager functions. Have a tee file enabled and pager set to less, and you
are able to browse the results using the less program and still have everything appended into a file the
same time. The difference between the Unix tee used with the pager command and the mysql built-in tee
command is that the built-in tee works even if you do not have the Unix tee available. The built-in tee
also logs everything that is printed on the screen, whereas the Unix tee used with pager does not log
quite that much. Additionally, tee file logging can be turned on and off interactively from within mysql.
This is useful when you want to log some queries to a file, but not others.
The prompt command reconfigures the default mysql> prompt. The string for defining the prompt can contain
the following special sequences.

You can set the prompt in several ways:
· Use an environment variable. You can set the MYSQL_PS1 environment variable to a prompt string. For
example:
shell> export MYSQL_PS1="(\u@\h) [\d]> "
· Use a command-line option. You can set the --prompt option on the command line to mysql. For
example:
shell> mysql --prompt="(\u@\h) [\d]> "
(user@host) [database]>
· Use an option file. You can set the prompt option in the [mysql] group of any MySQL option file,
such as /etc/my.cnf or the .my.cnf file in your home directory. For example:
[mysql]
prompt=(\\u@\\h) [\\d]>\\_
In this example, note that the backslashes are doubled. If you set the prompt using the prompt option
in an option file, it is advisable to double the backslashes when using the special prompt options.
There is some overlap in the set of permissible prompt options and the set of special escape
sequences that are recognized in option files. (The rules for escape sequences in option files are
listed in Section 4.2.6, “Using Option Files”.) The overlap may cause you problems if you use single
backslashes. For example, \s is interpreted as a space rather than as the current seconds value. The
following example shows how to define a prompt within an option file to include the current time in
HH:MM:SS> format:
[mysql]
prompt="\\r:\\m:\\s> "
· Set the prompt interactively. You can change your prompt interactively by using the prompt (or \R)
command. For example:
mysql> prompt (\u@\h) [\d]>\_
PROMPT set to '(\u@\h) [\d]>\_'
(user@host) [database]>
(user@host) [database]> prompt
Returning to default PROMPT of mysql>
mysql>
MYSQL LOGGING
On Unix, the mysql client logs statements executed interactively to a history file. By default, this file
is named .mysql_history in your home directory. To specify a different file, set the value of the
MYSQL_HISTFILE environment variable. How Logging Occurs.PP Statement logging occurs as follows:
· Statements are logged only when executed interactively. Statements are noninteractive, for example,
when read from a file or a pipe. It is also possible to suppress statement logging by using the
--batch or --execute option.
· mysql logs each nonempty statement line individually.
· If a statement spans multiple lines (not including the terminating delimiter), mysql concatenates the
lines to form the complete statement, maps newlines to spaces, and logs the result, plus a delimiter.
Consequently, an input statement that spans multiple lines can be logged twice. Consider this input:
mysql> SELECT
-> 'Today is'
-> ,
-> CONCAT()
-> ;
In this case, mysql logs the “SELECT”, “'Today is'”, “,”, “CONCAT()”, and “;” lines as it reads them. It
also logs the complete statement, after mapping SELECT\n'Today is'\n,\nCURDATE() to SELECT 'Today is' ,
CURDATE(), plus a delimiter. Thus, these lines appear in logged output:
SELECT
'Today is'
,
CURDATE()
;
SELECT 'Today is' , CURDATE();
Controlling the History File.PP The .mysql_history file should be protected with a restrictive access
mode because sensitive information might be written to it, such as the text of SQL statements that
contain passwords. See Section 6.1.2.1, “End-User Guidelines for Password Security”.
If you do not want to maintain a history file, first remove .mysql_history if it exists. Then use either
of the following techniques to prevent it from being created again:
· Set the MYSQL_HISTFILE environment variable to /dev/null. To cause this setting to take effect each
time you log in, put it in one of your shell's startup files.
· Create .mysql_history as a symbolic link to /dev/null; this need be done only once:
shell> ln -s /dev/null $HOME/.mysql_history
MYSQL SERVER-SIDE HELP
mysql> help search_string
If you provide an argument to the help command, mysql uses it as a search string to access server-side
help from the contents of the MySQL Reference Manual. The proper operation of this command requires that
the help tables in the mysql database be initialized with help topic information (see Section 5.1.10,
“Server-Side Help”).
If there is no match for the search string, the search fails:
mysql> help me
Nothing found
Please try to run 'help contents' for a list of all accessible topics
Use help contents to see a list of the help categories:
mysql> help contents
You asked for help about help category: "Contents"
For more information, type 'help <item>', where <item> is one of the
following categories:
Account Management
Administration
Data Definition
Data Manipulation
Data Types
Functions
Functions and Modifiers for Use with GROUP BY
Geographic Features
Language Structure
Plugins
Storage Engines
Stored Routines
Table Maintenance
Transactions
Triggers
If the search string matches multiple items, mysql shows a list of matching topics:
mysql> help logs
Many help items for your request exist.
To make a more specific request, please type 'help <item>',
where <item> is one of the following topics:
SHOW
SHOW BINARY LOGS
SHOW ENGINE
SHOW LOGS
Use a topic as the search string to see the help entry for that topic:
mysql> help show binary logs
Name: 'SHOW BINARY LOGS'
Description:
Syntax:
SHOW BINARY LOGS
SHOW MASTER LOGS
Lists the binary log files on the server. This statement is used as
part of the procedure described in [purge-binary-logs], that shows how
to determine which logs can be purged.
mysql> SHOW BINARY LOGS;
+---------------+-----------+
| Log_name | File_size |
+---------------+-----------+
| binlog.000015 | 724935 |
| binlog.000016 | 733481 |
+---------------+-----------+
The search string can contain the wildcard characters “%” and “_”. These have the same meaning as for
pattern-matching operations performed with the LIKE operator. For example, HELP rep% returns a list of
topics that begin with rep:
mysql> HELP rep%
Many help items for your request exist.
To make a more specific request, please type 'help <item>',
where <item> is one of the following
topics:
REPAIR TABLE
REPEAT FUNCTION
REPEAT LOOP
REPLACE
REPLACE FUNCTION
EXECUTING SQL STATEMENTS FROM A TEXT FILE
The mysql client typically is used interactively, like this:
shell> mysql db_name
However, it is also possible to put your SQL statements in a file and then tell mysql to read its input
from that file. To do so, create a text file text_file that contains the statements you wish to execute.
Then invoke mysql as shown here:
shell> mysql db_name < text_file
If you place a USE db_name statement as the first statement in the file, it is unnecessary to specify the
database name on the command line:
shell> mysql < text_file
If you are already running mysql, you can execute an SQL script file using the source command or \.
command:
mysql> source file_name
mysql> \. file_name
Sometimes you may want your script to display progress information to the user. For this you can insert
statements like this:
SELECT '<info_to_display>' AS ' ';
The statement shown outputs <info_to_display>.
You can also invoke mysql with the --verbose option, which causes each statement to be displayed before
the result that it produces.
mysql ignores Unicode byte order mark (BOM) characters at the beginning of input files. Previously, it
read them and sent them to the server, resulting in a syntax error. Presence of a BOM does not cause
mysql to change its default character set. To do that, invoke mysql with an option such as
--default-character-set=utf8.
For more information about batch mode, see Section 3.5, “Using mysql in Batch Mode”.
MYSQL TIPS
This section describes some techniques that can help you use mysql more effectively.
Input-Line Editing
mysql supports input-line editing, which enables you to modify the current input line in place or recall
previous input lines. For example, the left-arrow and right-arrow keys move horizontally within the
current input line, and the up-arror and down-arrow keys move up and down through the set of previously
entered lines. Backspace deletes the character before the cursor and typing new characters enters them
at the cursor position. To enter the line, press Enter.
On Windows, the editing key sequences are the same as supported for command editing in console windows.
On Unix, the key sequences depend on the input library used to build mysql (for example, the libedit or
readline library).
Documentation for the libedit and readline libraries is available online. To change the set of key
sequences permitted by a given input library, define key bindings in the library startup file. This is a
file in your home directory: .editrc for libedit and .inputrc for readline.
For example, in libedit, Control+W deletes everything before the current cursor position and Control+U
deletes the entire line. In readline, Control+W deletes the word before the cursor and Control+U deletes
everything before the current cursor position. If mysql was built using libedit, a user who prefers the
readline behavior for these two keys can put the following lines in the .editrc file (creating the file
if necessary):
bind "^W" ed-delete-prev-word
bind "^U" vi-kill-line-prev
To see the current set of key bindings, temporarily put a line that says only bind at the end of .editrc.
mysql will show the bindings when it starts.
Displaying Query Results Vertically
Some query results are much more readable when displayed vertically, instead of in the usual horizontal
table format. Queries can be displayed vertically by terminating the query with \G instead of a
semicolon. For example, longer text values that include newlines often are much easier to read with
vertical output:
mysql> SELECT * FROM mails WHERE LENGTH(txt) < 300 LIMIT 300,1\G
*************************** 1. row ***************************
msg_nro: 3068

Using the --safe-updates Option
For beginners, a useful startup option is --safe-updates (or --i-am-a-dummy, which has the same effect).
It is helpful for cases when you might have issued a DELETE FROM tbl_name statement but forgotten the
WHERE clause. Normally, such a statement deletes all rows from the table. With --safe-updates, you can
delete rows only by specifying the key values that identify them. This helps prevent accidents.
When you use the --safe-updates option, mysql issues the following statement when it connects to the
MySQL server:
SET sql_safe_updates=1, sql_select_limit=1000, sql_max_join_size=1000000;
See Section 5.1.4, “Server System Variables”.
The SET statement has the following effects:
· You are not permitted to execute an UPDATE or DELETE statement unless you specify a key constraint in
the WHERE clause or provide a LIMIT clause (or both). For example:
UPDATE tbl_name SET not_key_column=val WHERE key_column=val;
UPDATE tbl_name SET not_key_column=val LIMIT 1;
· The server limits all large SELECT results to 1,000 rows unless the statement includes a LIMIT
clause.
· The server aborts multiple-table SELECT statements that probably need to examine more than 1,000,000
row combinations.
To specify limits different from 1,000 and 1,000,000, you can override the defaults by using the
--select_limit and --max_join_size options:
shell> mysql --safe-updates --select_limit=500 --max_join_size=10000
Disabling mysql Auto-Reconnect
If the mysql client loses its connection to the server while sending a statement, it immediately and
automatically tries to reconnect once to the server and send the statement again. However, even if mysql
succeeds in reconnecting, your first connection has ended and all your previous session objects and
settings are lost: temporary tables, the autocommit mode, and user-defined and session variables. Also,
any current transaction rolls back. This behavior may be dangerous for you, as in the following example
where the server was shut down and restarted between the first and second statements without you knowing
it:
mysql> SET @a=1;
Query OK, 0 rows affected (0.05 sec)
mysql> INSERT INTO t VALUES(@a);
ERROR 2006: MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 1
Current database: test
Query OK, 1 row affected (1.30 sec)
mysql> SELECT * FROM t;
+------+
| a |
+------+
| NULL |
+------+
1 row in set (0.05 sec)
The @a user variable has been lost with the connection, and after the reconnection it is undefined. If it
is important to have mysql terminate with an error if the connection has been lost, you can start the
mysql client with the --skip-reconnect option.
For more information about auto-reconnect and its effect on state information when a reconnection occurs,
see Section 23.8.16, “Controlling Automatic Reconnection Behavior”.

Приложение. Лог неправильной уатновки phpmyadmin¶
Процесс установки пришлось прервать, так как предварительно надо было запустить mysql сервер, а я его даже не проверил и, как выяснилось, у меня клиента вообще не стояло...
Дело было в воскресенье. И мое разгильдяйство можно объяснить (но не оправдать) тем, что я этих баз данных и ...админов понаустанавливал десятка 2... но последний раз это делал лет пять назад. Надо было тупо и последоватльно выполнять инструкцию How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Debian, но мной овладела гордыня.

Я пренебрег простым правилом "не делать лишнего" и решил между делао установить phpmyadmin..., так на всякий случай, она мен у нужна то не была... В результате попал в глупое положение. Пришлось бросить установку... а надо было выполнить последовательный минимум шагов. В частности, проверить что там в Kali предустановлено (клиента mysql не оказалось)
