语法图
- SetPasswordStmt
SetPasswordStmt ::=
"SET" "PASSWORD" ( "FOR" Username )? "=" ( stringLit | "PASSWORD" "(" stringLit ")" )
示例
SET PASSWORD='test';
Query OK, 0 rows affected (0.01 sec)
CREATE USER 'newuser' IDENTIFIED BY 'test';
Query OK, 1 row affected (0.00 sec)
SHOW CREATE USER 'newuser';
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER for newuser@% |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER 'newuser'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
SET PASSWORD FOR 'newuser' = 'test';
Query OK, 0 rows affected (0.01 sec)
SHOW CREATE USER 'newuser';
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER for newuser@% |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER 'newuser'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
SET PASSWORD FOR 'newuser' = PASSWORD('test');
上述语法是早期 MySQL 版本的过时语法。
Query OK, 0 rows affected (0.00 sec)
SHOW CREATE USER 'newuser';
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER for newuser@% |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER 'newuser'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
