MySQL使用变量创建用户？

我想做到这一点：MySQL使用变量创建用户？

#Variables 
SET @username="jdoe", @password="secret"; 

# Insert a new MySQL User 
CREATE USER @[email protected]'localhost' IDENTIFIED BY @password;GRANT USAGE ON *.* TO @[email protected]'localhost' IDENTIFIED BY @password WITH MAX_QUERIES_PER_HOUR 120 MAX_CONNECTIONS_PER_HOUR 60 MAX_UPDATES_PER_HOUR 60 MAX_USER_CONNECTIONS 2;

但得到：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '@[email protected]'localhost' IDENTIFIED BY @password' at line 2

如何在CREATE USER语句中使用一个变量？

@aleroot我不确定这是相同的问题，因为它涉及到创建存储过程。 – Nick 2012-08-14 12:19:39

您可以使用dynamic SQL为：

SET @query1 = CONCAT(' 
     CREATE USER "',@username,'"@"localhost" IDENTIFIED BY "',@password,'" ' 
     ); 
PREPARE stmt FROM @query1; EXECUTE stmt; DEALLOCATE PREPARE stmt; 

SET @query1 = CONCAT(' 
    GRANT USAGE ON *.* TO "',@username,'"@"localhost" IDENTIFIED BY "',@password,'" WITH 
      MAX_QUERIES_PER_HOUR 120 MAX_CONNECTIONS_PER_HOUR 60 MAX_UPDATES_PER_HOUR 60 
      MAX_USER_CONNECTIONS 2' 
     ); 
PREPARE stmt FROM @query1; EXECUTE stmt; DEALLOCATE PREPARE stmt;

这似乎没有工作......我得到'＃1064 - 你的SQL语法有错误;检查与您的MySQL服务器版本相对应的手册，以获得在'secret'附近使用的正确语法; 授予使用*。*到jdoe @'localhost'IDENTIFIED BY secret 'at line 1' – Nick 2012-08-14 11:56:37

错过了引号。尝试更新查询。 – Omesh 2012-08-14 12:36:20

非常好，谢谢！ – Nick 2012-08-14 12:44:17
