6.5.1.6 mysql Client Tips

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().

Note

Alternatively, MySQL Shell offers access to the X DevAPI. For details, see MySQL Shell 9.0.

Using mysql is very easy. Invoke it from the prompt of your command interpreter as follows:

mysql db_name

Or:

mysql --user=user_name --password db_name

In this case, you'll need to enter your password in response to the prompt that mysql displays:

Enter password: your_password

Then type an SQL statement, end it with ;, \g, or \G and press Enter.

Typing Control+C interrupts the current statement if there is one, or cancels any partial input line otherwise.

You can execute SQL statements in a script file (batch file) like this:

mysql db_name < script.sql > output.tab

On Unix, the mysql client logs statements executed interactively to a history file. See Section 6.5.1.3, “mysql Client Logging”.
