The SHOW statement can display the value of either one or all of the session setting variables. Some of these can also be configured via SET.

Required Privileges

No privileges are required to display the session settings.

Synopsis

SHOW var_name ALL
Note:
The SHOW statement for session settings is unrelated to the other SHOW statements: SHOW CLUSTER SETTING, SHOW CREATE TABLE, SHOW CREATE VIEW, SHOW USERS, SHOW DATABASES, SHOW COLUMNS, SHOW GRANTS, and SHOW CONSTRAINTS.

Parameters

The SHOW <session variable> statement accepts a single parameter: the variable name.

The variable name is case insensitive. It may be enclosed in double quotes; this is useful if the variable name itself contains spaces.
