与UNION一起使用时，每个SQL Server查询的排序都不起作用

Question

我必须合并来自3个不同列的数据，这些表具有不同的列，我希望的输出应该基于每个表的不同排序条件。

我在下面使用此查询，但此查询基于菜单位置对整体结果进行排序，如何更改此查询以对单个查询的结果进行排序

SELECT DISTINCT 
     PID, MENU, Handler, PageLangID, ParentID, IssueID, CatID, MenuPosition 
FROM (
   --Pages Table 
   SELECT TOP 50 
       PageId AS PID,SUBSTRING(PageName,0,20) AS MENU,SUBSTRING(PageInternalLinkURL,0,24) AS Handler, PageLangID,PageInheritance AS ParentID, 1 AS IssueID, 1 AS CatID, 
        PageLinkPosition as MenuPosition  FROM pg_Pages  WHERE PageLangID = 1  ORDER BY PageLinkPosition DESC 
UNION 
--Article Category Table
SELECT TOP 20 p.PageID AS PID, SUBSTRING(c.ArticleCategoryName,0,20) AS MENU,SUBSTRING(p.PageInternalLinkURL,0,24) AS Handler, 
c.LangID,p.PageID,1, ArticleCategoryID, 1 AS MenuPosition FROM art_Category c JOIN pg_Pages p 
ON c.PageID = p.PageID  JOIN art_CategoryType ct ON c.Type = ct.CategoryTypeID WHERE c.LangID =1  AND c.Type =1 
ORDER BY c.ArticleCategoryName  
UNION 
--Magazine Table
SELECT TOP 10 p.PageID AS PID, CAST(IssueCode AS varchar(10)),SUBSTRING(p.PageInternalLinkURL,0,24) AS Handler,LangID,p.PageID AS ParentID, m.IssueID AS IssueID, 1, 
       1 AS MenuPosition FROM Magazine m   JOIN pg_pages p ON m.PageID = p.PageID   WHERE LangID =1  ORDER BY 2 DESC  
) AS T  WHERE T.PageLangID = 1 ORDER BY MenuPosition

第二种方式

如果我使用下面的查询，那么我得到以下错误

消息156，第15级，状态1，第4行
关键字“UNION”附近的语法不正确。
消息156，第15级，状态1，第10行
关键字“UNION”附近的语法不正确。

我想要第一个查询按ORDER BY PageLinkPosition DESC排序

第二个查询按ORDER BY c.ArticleCategoryName ASC排序ORDER BY c.ArticleCategoryName ASC

和第三个查询按ORDER BY IssueCode DESC排序

我尝试了很多方法，但无法正常工作。

在这方面表示感谢

更新 ：基于Mark Solution的工作查询，只有很小的变化
