Sql In子句语法查询错误

我想从数据库中的messages表中提取单个用户的消息，我编写的查询有一些语法问题，但我不知道如何修复它。请帮忙

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)

---

它遗漏了一些东西

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)

不需要

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

感觉它的重复性少了一点。

你想找到什么？用户1和联系人编号为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试图找到的内容的解释。一些示例数据和预期结果不会有任何影响。@Damien_不信者是的，先生，我想查找用户1和ContactNo=03005114812之间的消息，先生，我不知道缺少了什么，我试了很多次，但成功了。别介意，我没有任何声誉来证明它是正确的，但我已经投了一票。谢萨洛特

             (m.ReceiverId = u.UserId and m.SenderId = 1)
WHERE
    u.ContactNo = 03005114812
