请问为什么我执行以下语句会报错？
err := a.MysqlDB.db.Exec("CREATE USER ? IDENTIFIED BY ?", a.Name, a.Pwd).Error
报错信息为
[1.918ms] [rows:0] CREATE USER 'Reiis' IDENTIFIED BY '12345'
Error 1064 (42000): 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 '? IDENTIFIED BY ?' at line 1
而我不管是拼接字符串还是直接在mysql中执行上述sql语句，都是能成功运行的。
以下代码可以成功运行：
cmd := fmt.Sprintf("CREATE USER '%s' IDENTIFIED BY '%s'", a.Name, a.Pwd)
err := a.MysqlDB.db.Exec(cmd).Error
请问什么原因呢？谢谢🙏

@John-0xFFFFFF it's not a gorm problem, it's a mysql problem.
you can check this link to see why you cannot using a prepared statement with placeholder to do this: https://stackoverflow.com/questions/67047078/create-user-and-create-role-as-preparedstatement-with-placeholder
and you can check this link to see how you can achieve your goal by work around: https://stackoverflow.com/questions/35749340/create-user-fails-with-mysqli-prepared-statements, but as what it says: with users created dynamically you are doing something wrong

@jinzhu maybe just close this issue as it's not a gorm problem(what I mentioned above).
