在尝试为我的第二个wiki创建数据库时，我遇到了设置单独数据库的问题。我首先得到一个拒绝访问的错误，然后我得到一个数据库查询错误。我一直在使用putty来修复回溯错误，但是在另一个线程上执行命令时它没有显示消息。如何使用putty修复数据库查询错误？查询错误如下所示：
查询：

SELECT user_id, user_name,
user_real_name, user_email, user_touched, user_token, user_email_authenticated, user_email_token, user_email_token_expires, user_registration, user_editcount FROM gjlxrtap_mw19758.mwd50q_user WHERE user_id = '1' LIMIT 1 Function:

User::loadFromDatabase

Error:

1142 SELECT command denied to user 'gjlxrtap_wiki2'@'localhost' for table 'mwd50q_user' (localhost)

Backtrace:
