The ENABLED_ROLES table was introduced in MariaDB 10.0.5

The Information Schema ENABLED_ROLES table shows the enabled roles for the current session.

It contains the following column:

ColumnDescription
ROLE_NAMEThe enabled role name, or NULL.

This table lists all roles that are currently enabled, one role per row — the current role, roles granted to the current role, roles granted to these roles and so on. If no role is set, the row contains a NULL value.

The roles that the current user can enable are listed in the APPLICABLE_ROLES Information Schema table.

See also CURRENT_ROLE().
