SHOW TABLE_STATISTICS

MariaDB starting with 5.2

MariaDB 5.2 introduced the User Statistics feature.

Syntax

SHOW TABLE_STATISTICS

Description

The SHOW TABLE_STATISTICS statement was introduced in MariaDB 5.2 as part of the User Statistics feature. It was removed as a separate statement in MariaDB 10.1.1, but effectively replaced by the generic SHOW information_schema_table statement. The information_schema.TABLE_STATISTICS table shows statistics on table usage

The userstat system variable must be set to 1 to activate this feature. See the User Statistics and information_schema.TABLE_STATISTICS articles for more information.

Example

From MariaDB 10.0
