SQL查询内部联接

我想修改我的论坛代码中的一个查询，从表tblProfile返回两个字段。此表有两个字段，“EmailAddress”和“EmailVerified”

这是原始查询：

SELECT * 
FROM   (SELECT TOP 10 [Scirra].[dbo].[tblForumThread].thread_id, 
                      [Scirra].[dbo].[tblForumThread].MESSAGE, 
                      [Scirra].[dbo].[tblForumThread].message_date, 
                      [Scirra].[dbo].[tblForumThread].show_signature, 
                      [Scirra].[dbo].[tblForumThread].ip_addr, 
                      [Scirra].[dbo].[tblForumThread].hide, 
                      [Scirra].[dbo].[tblForumAuthor].author_id, 
                      [Scirra].[dbo].[tblForumAuthor].username, 
                      [Scirra].[dbo].[tblForumAuthor].homepage, 
                      [Scirra].[dbo].[tblForumAuthor].location, 
                      [Scirra].[dbo].[tblForumAuthor].no_of_posts, 
                      [Scirra].[dbo].[tblForumAuthor].join_date, 
                      [Scirra].[dbo].[tblForumAuthor].SIGNATURE, 
                      [Scirra].[dbo].[tblForumAuthor].active, 
                      [Scirra].[dbo].[tblForumAuthor].avatar, 
                      [Scirra].[dbo].[tblForumAuthor].avatar_title, 
                      [Scirra].[dbo].[tblForumGroup].name 
                             AS groupname, 
                      [Scirra].[dbo].[tblForumGroup].stars, 
                      [Scirra].[dbo].[tblForumGroup].custom_stars, 
                      [Scirra].[dbo].[tblForumGuestName].name 
                             AS guestname, 
                      Row_number() OVER (ORDER BY 
                             [Scirra].[dbo].[tblForumThread].message_date ASC) 
                      AS 
                      rownum
        FROM   ([Scirra].[dbo].[tblForumGroup] 
                INNER JOIN ([Scirra].[dbo].[tblForumAuthor] 
                INNER JOIN [Scirra].[dbo].[tblForumThread] 

                ON [Scirra].[dbo].[tblForumAuthor].author_id = [Scirra].[dbo].[tblForumThread].author_id) 
                ON [Scirra].[dbo].[tblForumGroup].group_id = [Scirra].[dbo].[tblForumAuthor].group_id) 
                LEFT JOIN [Scirra].[dbo].[tblForumGuestName] 
                ON [Scirra].[dbo].[tblForumThread].thread_id = [Scirra].[dbo].[tblForumGuestName].thread_id 
        WHERE


          [Scirra].[dbo].[tblForumThread].topic_id = 33854 
               AND ( [Scirra].[dbo].[tblForumThread].hide = 0 
                      OR [Scirra].[dbo].[tblForumThread].author_id = 13405 ))



                       AS 
       pagingquery 
WHERE  rownum BETWEEN 1 AND 10; 

在选择字段方面，我已经做到了：

 ,
 [Scirra].[dbo].[tblProfile].EmailAddress, 
 [Scirra].[dbo].[tblProfile].EmailVerified

但我有点被困在那个窝里了

感谢您的帮助

对不起！我需要将tblProfile.UserID与tblautor.author\u ID一起加入tblProfile.UserID。您需要在tblProfile上添加一个

join

：

INNER JOIN [Scirra].[dbo].[tblProfile]   as tp
ON tblAuthor.author_ID  = tp.user_id

没有这一点，就无法参考

 [Scirra].[dbo].[tblProfile].EmailAddress, 
 [Scirra].[dbo].[tblProfile].EmailVerified

您可以将其放在tblForumAuthor

JOIN

之后的任意位置。好的，如果我正确理解了您的查询，您可以尝试以下操作：

SELECT * 
FROM   (SELECT TOP 10 [Scirra].[dbo].[tblForumThread].thread_id, 
                      [Scirra].[dbo].[tblForumThread].MESSAGE, 
                      [Scirra].[dbo].[tblForumThread].message_date, 
                      [Scirra].[dbo].[tblForumThread].show_signature, 
                      [Scirra].[dbo].[tblForumThread].ip_addr, 
                      [Scirra].[dbo].[tblForumThread].hide, 
                      [Scirra].[dbo].[tblForumAuthor].author_id, 
                      [Scirra].[dbo].[tblForumAuthor].username, 
                      [Scirra].[dbo].[tblForumAuthor].homepage, 
                      [Scirra].[dbo].[tblForumAuthor].location, 
                      [Scirra].[dbo].[tblForumAuthor].no_of_posts, 
                      [Scirra].[dbo].[tblForumAuthor].join_date, 
                      [Scirra].[dbo].[tblForumAuthor].SIGNATURE, 
                      [Scirra].[dbo].[tblForumAuthor].active, 
                      [Scirra].[dbo].[tblForumAuthor].avatar, 
                      [Scirra].[dbo].[tblForumAuthor].avatar_title, 
                      [Scirra].[dbo].[tblForumGroup].name

                      [Scirra].[dbo].[tblForumGuestName].name 
                             AS guestname, 
                      [Scirra].[dbo].[tblProfile].EmailAddress, 
                      [Scirra].[dbo].[tblProfile].EmailVerified,
                      Row_number() OVER (ORDER BY 
                             [Scirra].[dbo].[tblForumThread].message_date ASC) 
                      AS 
                      rownum

              AND ([Scirra].[dbo].[tblForumThread].hide = 0 OR [Scirra].[dbo].[tblForumThread].author_id = 13405 )) AS pagingquery

您的

tblProfile

表的其他字段是什么？这样我们就可以知道如何将它与其他表连接起来。@Lamak抱歉！我需要加入tblProfile.UserID和tblAuthor.author_ID@Abe是的，天哪，我累了，对不起，谢谢，但我一直在想该把加入放在哪里，我不太擅长，我一辈子都不知道该怎么把它和其他人放在一起。你是说TBlautor还是说tblForumAuthor？我这样问是因为该表似乎不是您的查询的一部分。是的，对不起，今晚的表名是对的，我得到了

无法绑定的多部分标识符“Scirra.dbo.tblProfile.EmailAddress”。

谢谢，其他答案得到了，但是+1感谢您的帮助，再次感谢
