MySQL 5.7 Reference Manual  /  ...  /  The INFORMATION_SCHEMA GLOBAL_STATUS and SESSION_STATUS Tables

24.3.10 The INFORMATION_SCHEMA GLOBAL_STATUS and SESSION_STATUS Tables

Note

The value of the show_compatibility_56 system variable affects the information available from the tables described here. For details, see the description of that variable in Section 5.1.7, “Server System Variables”.

Note

Information available from the tables described here is also available from the Performance Schema. The INFORMATION_SCHEMA tables are deprecated in preference to the Performance Schema tables and are removed in MySQL 8.0. For advice on migrating away from the INFORMATION_SCHEMA tables to the Performance Schema tables, see Section 25.20, “Migrating to Performance Schema System and Status Variable Tables”.

The GLOBAL_STATUS and SESSION_STATUS tables provide information about server status variables. Their contents correspond to the information produced by the SHOW GLOBAL STATUS and SHOW SESSION STATUS statements (see Section 13.7.5.35, “SHOW STATUS Statement”).

Notes

  • The VARIABLE_VALUE column for each of these tables is defined as VARCHAR(1024).
