mariadb-find-rows

mariadb-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.

Previously, the client was called mysql_find_rows. It can still be accessed under this name, via a symlink in Linux, or an alternate binary in Windows.

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.

Usage

mariadb-find-rows [options] [file_name ...]

Each file_name argument should be the name of file containing SQL statements. If no file names are given, the tool reads from stdin (standard input).

Options

mariadb-find-rows supports the following options:

Option	Description
--help, --Information	Display help and exit.
--regexp=pattern	Display queries that match 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 (first row is 1).

Examples

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