Usage Notes

  • The view only displays objects for which the current role for the session has been granted access privileges. The view does not honor the MANAGE GRANTS privilege and consequently may show less information compared to a SHOW command when both are executed by a user who holds the MANAGE GRANTS privilege.

  • Querying the sum(bytes) for a table does not represent the total storage usage, because the amount does not include Time Travel and Fail-safe usage.

  • The view does not include tables that have been dropped. To view dropped tables, use SHOW TABLES instead.

  • To view only tables in your queries, filter using a WHERE clause, e.g.:

    ... WHERE table_schema != 'INFORMATION_SCHEMA'

Examples

Retrieve the size (in bytes) of all tables in all schemas in the mydatabase database:

SELECT TABLE_SCHEMA,SUM(BYTES)
    FROM mydatabase.information_schema.tables
    GROUP BY TABLE_SCHEMA;
