SHOW STATS_META

You can use SHOW STATS_META to view how many rows are in a table and how many rows are changed in that table. When using this statement, you can filter the needed information by the ShowLikeOrWhere clause.

Currently, the SHOW STATS_META statement outputs 6 columns:

Syntax elementDescription
db_nameDatabase name
table_nameTable name
partition_namePartition name
update_timeLast updated time
modify_countThe number of rows modified
row_countThe total row count
Note

The update_time is updated when TiDB updates the modify_count and row_count fields according to DML statements. So update_time is not the last execution time of the ANALYZE statement.
