SET PASSWORD 语句用于更改 TiDB 系统数据库中的用户密码。

语法图

SetStmt:

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)
