mysql_find_rows

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.

From MariaDB 10.4.6, mariadb-find-rows is a symlink to mysql_find_rows.

Usage

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.

Options

mysql_find_rows supports the following options:

OptionDescription
--help, --InformationDisplay help and exit.
--regexp=patternDisplay queries that match the pattern.
--rows=NQuit after displaying N queries.
--skip-use-dbDo not include USE db_name statements in the output.
--start_row=NStart output from this row (first row is 1).

Examples

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