示例

  1. SET PASSWORD='test';
  1. Query OK, 0 rows affected (0.01 sec)
  1. CREATE USER 'newuser' IDENTIFIED BY 'test';
  1. Query OK, 1 row affected (0.00 sec)
  1. SHOW CREATE USER 'newuser';
  1. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  2. | CREATE USER for newuser@% |
  3. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  4. | CREATE USER 'newuser'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
  5. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  6. 1 row in set (0.00 sec)
  1. SET PASSWORD FOR 'newuser' = 'test';
  1. Query OK, 0 rows affected (0.01 sec)
  1. SHOW CREATE USER 'newuser';
  1. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  2. | CREATE USER for newuser@% |
  3. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  4. | CREATE USER 'newuser'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
  5. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  6. 1 row in set (0.00 sec)
  1. SET PASSWORD FOR 'newuser' = PASSWORD('test');

上述语法是早期 MySQL 版本的过时语法。

  1. Query OK, 0 rows affected (0.00 sec)
  1. SHOW CREATE USER 'newuser';
  1. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  2. | CREATE USER for newuser@% |
  3. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  4. | CREATE USER 'newuser'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
  5. +----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
  6. 1 row in set (0.00 sec)
