CREATE USER @user@@@host IDENTIFIED BY @pwd 用的这个sql，生成的sql语句放到数据库运行不报错，但是运行报错

 For example:> "CREATE USER 'text'@'%' IDENTIFIED BY '111';"

java代码贴一下

StringBuilder sql = new StringBuilder();
        sql.append("CREATE USER @user@@@host IDENTIFIED BY @pwd;");
        Sql sqls = Sqls.create(sql.toString());
        sqls.params().set("user", user).set("host",host).set("pwd", pwd);
        dao.execute(sqls);

这种SQL是不能用参数形式的, 改为用变量吧

我试试

好了，确实不能用参数形式，谢谢
