SHOW GRANTS

This statement shows a list of privileges associated with a user. As in MySQL, the USAGE privileges denotes the ability to login to TiDB.

Synopsis

ShowGrantsStmt ::=
    "SHOW" "GRANTS" ("FOR" Username ("USING" RolenameList)?)?

Username ::=
    "CURRENT_USER" ( "(" ")" )?
| Username ("@" Hostname)?

RolenameList ::=
    Rolename ("@" Hostname)? ("," Rolename ("@" Hostname)? )*

Examples

mysql> SHOW GRANTS;

+-------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' |
+-------------------------------------------+
