GRANTEE

The name of the account to which the privilege is granted, in 'user_name'@'host_name' format.

TABLE_CATALOG

The name of the catalog. This value is always def.

PRIVILEGE_TYPE

The privilege granted. The value can be any privilege that can be granted at the global level; see Section 15.7.1.6, “GRANT Statement”. Each row lists a single privilege, so there is one row per global privilege held by the grantee.

IS_GRANTABLE

YES if the user has the GRANT OPTION privilege, NO otherwise. The output does not list GRANT OPTION as a separate row with PRIVILEGE_TYPE='GRANT OPTION'.

USER_PRIVILEGES is a nonstandard INFORMATION_SCHEMA table.
