PROCESS權限，可以執行解釋執行計劃操作的權限（需要額外授予表上的select權限）。
當然也隱式激活很多其他操作。比如show engines，show processlist等。
比如：
mysql> show grants for 'ut01'@'%';
+----------------------------------+
| Grants for ut01@% |
+----------------------------------+
| GRANT USAGE ON *.* TO 'ut01'@'%' |
+----------------------------------+
1 row in set (0.00 sec)
mysql> grant process on test.* to 'ut01'@'%';
ERROR 1221 (HY000): Incorrect usage of DB GRANT and GLOBAL PRIVILEGES
mysql> grant process on *.* to 'ut01'@'%';
Query OK, 0 rows affected (0.05 sec)
mysql> show grants for 'ut01'@'%';
+------------------------------------+
| Grants for ut01@% |
+------------------------------------+
| GRANT PROCESS ON *.* TO 'ut01'@'%' |
+------------------------------------+
1 row in set (0.00 sec)
mysql> alter user 'ut01'@'%' identified by '20127163';
Query OK, 0 rows affected (0.05 sec)
mysql> grant select on test.* to 'ut01'@'%';
Query OK, 0 rows affected (0.05 sec)
