MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6
The USER_PRIVILEGES table provides
information about global privileges. It takes its values from the
mysql.user system table.
The USER_PRIVILEGES table has these
columns:
GRANTEE
The name of the account to which the privilege is granted, in
'
format.
user_name'@'host_name'
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 13.7.1.4, “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.
The following statements are not equivalent:
SELECT ... FROM INFORMATION_SCHEMA.USER_PRIVILEGES SHOW GRANTS ...
