MySQL 5.6 Reference Manual  /  INFORMATION_SCHEMA Tables  /  The INFORMATION_SCHEMA GLOBAL_VARIABLES and SESSION_VARIABLES Tables

21.10 The INFORMATION_SCHEMA GLOBAL_VARIABLES and SESSION_VARIABLES Tables

The GLOBAL_VARIABLES and SESSION_VARIABLES tables provide information about server status variables. Their contents correspond to the information produced by the SHOW GLOBAL VARIABLES and SHOW SESSION VARIABLES statements (see Section 13.7.5.40, “SHOW VARIABLES Syntax”).

Notes

  • The VARIABLE_VALUE column for each of these tables is defined as VARCHAR(1024). For variables with very long values that are not completely displayed, use SELECT as a workaround. For example:

    SELECT @@GLOBAL.innodb_data_file_path;
