Short description:

Manual page and help for the mysql_find_rows linux command. Mysql_find_rows reads files that contain SQL statements that match a particular regular expression or that contain USE db_name or SET statements. The utility was written to update log files (used before MySQL 5.0) and expects instructions to end with a semicolon (;). It can also be useful for processing other files that contain SQL statements, as long as the statements end in a semicolon.

 

 

Man page output

man mysql_find_rows
MYSQL_FIND_ROWS                    MariaDB Database System                   MYSQL_FIND_ROWS

NAME
       mysql_find_rows - extract SQL statements from files

SYNOPSIS
       mysql_find_rows [options] [file_name ...]

DESCRIPTION
       mysql_find_rows reads files containing SQL statements and extracts statements that
       match a given regular expression or that contain USE db_name or SET statements. The
       utility was written for use with update log files (as used prior to MySQL 5.0) and as
       such expects statements to be terminated with semicolon (;) characters. It may be
       useful with other files that contain SQL statements as long as statements are
       terminated with semicolons.

       Invoke mysql_find_rows like this:

           shell> mysql_find_rows [options] [file_name ...]

       Each file_name argument should be the name of file containing SQL statements. If no
       file names are given, mysql_find_rows reads the standard input.

       Examples:

           mysql_find_rows --regexp=problem_table --rows=20 < update.log
           mysql_find_rows --regexp=problem_table  update-log.1 update-log.2

       mysql_find_rows supports the following options:

       •   --help, --Information

           Display a help message and exit.

       •   --regexp=pattern

           Display queries that match the pattern.

       •   --rows=N

           Quit after displaying N queries.

       •   --skip-use-db

           Do not include USE db_name statements in the output.

       •   --start_row=N

           Start output from this row.
