Sql In子句语法查询错误

我想从我的数据库中的消息表中为单个用户提取消息，我写的查询有一些语法问题，但我不知道如何解决它。请帮助Sql In子句语法查询错误

SELECT * 
FROM Messages 
WHERE SenderId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) 
    or ReceiverId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) 
    IN (SELECT * FROM Messages WHERE SenderId = 1 or ReceiverId = 1)

你在找什么？用户1与联系人号码为03005114812的用户之间的所有消息？如果不是这样，那么请添加更多关于您想要查找的内容的解释。一些样本数据和预期结果不会受到影响。 –

@Damien_The_Unbeliever是先生我想找到用户1和ContactNo = 03005114812 – ShodowOverRide

无需一个IN()搜索

SELECT * 
FROM Messages 
WHERE 
    (SenderId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) and 
    ReceiverId = 1) or 
    (ReceiverId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) and 
    SenderId = 1)

或者：

SELECT m.* 
FROM Messages m 
     INNER JOIN 
    Users u 
     on 
      (m.SenderId = u.UserId and m.ReceiverId = 1) or 
      (m.ReceiverId = u.UserId and m.SenderId = 1) 
WHERE 
    u.ContactNo = 03005114812

这感觉就像是有一点点重复少它。

谢谢先生，工作。不介意我没有任何声誉来标记它是正确的，但我已经给它一票。非常感谢 – ShodowOverRide

它失去了一些东西

WHERE SenderId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) 
or ReceiverId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) 
<missing expression here> IN (SELECT * FROM Messages WHERE SenderId = 1 or ReceiverId = 1)

UPDATE可能是如id列，如果你拥有了它在messages表

WHERE SenderId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) 
or ReceiverId = (SELECT UserId FROM Users WHERE ContactNo = 03005114812) 
id IN (SELECT id FROM Messages WHERE SenderId = 1 or ReceiverId = 1)
