+
+|                  **参数**                  |                       **描述**                       |

+| user_name                                | 用户名，新建用户后，"mysql.user"表会新增一行该用户的表项。如果同名用户已经存在，则报错。 |
+| IDENTIFIED BY                            | 使用自选的 IDENTIFIED BY 子句，可以为账户给定一个密码。                |
+| user_name \[, user_name ...\]            | 同时创建多个用户时，用","隔开。                                  |
+| user IDENTIFIED BY  'authstring'         | 此处密码为明文，存入"mysql.user"表后，服务器端会变为密文存储下来。            |
+| user IDENTIFIED BY PASSWORD 'hashstring' | 此处密码为密文。                                           |

+
+
+示例 
+-----------
+
+1. 执行以下命令创建名为 sqluser01 和 sqluser02 的用户，密码均为 123456。 
+
+
+
+
+```javascript
+CREATE USER 'sqluser01' IDENTIFIED BY '123456', 'sqluser02' IDENTIFIED BY '123456';
+```
+
+
+
+2. 执行以下命令查看创建的用户。
+
+
+
+
+```javascript
+SELECT user FROM mysql.user;
+```
+
+
+
+执行结果如下所示。
+
+```javascript
+mysql> CREATE USER 'sqluser01' IDENTIFIED BY '123456', 'sqluser02' IDENTIFIED BY '123456';
+Query OK, 0 rows affected (0.12 sec)
