Tsql联合查询正在打破我的asp.net gridview排序

Question

我有一个存储过程，它自己正常工作。最近的一项要求让我觉得Union查询将会完成我所需要的。这是工作版本。它使用ROW_NUMBER（）来实现分页和排序正确

SELECT x.TicketID, 
x.TicketNumber, 
x.AccountID, 
x.SkillID 
FROM (
SELECT ROW_NUMBER() OVER(ORDER BY 
    CASE WHEN @ipv_SortExpression = 'TicketNumber' AND @ipv_SortDirection = 'ASC' THEN y.TicketNumber END ASC, 
    CASE WHEN @ipv_SortExpression = 'TicketNumber' AND @ipv_SortDirection = 'DESC' THEN y.TicketNumber END DESC,    
    CASE WHEN @ipv_SortExpression = 'AccountNumber' AND @ipv_SortDirection = 'ASC' THEN y.AccountNumber END ASC, 
    CASE WHEN @ipv_SortExpression = 'AccountNumber' AND @ipv_SortDirection = 'DESC' THEN y.AccountNumber END DESC,    
    CASE WHEN @ipv_SortExpression = 'OpenDate' AND @ipv_SortDirection = 'ASC' THEN y.OpenDate END ASC, 
    CASE WHEN @ipv_SortExpression = 'OpenDate' AND @ipv_SortDirection = 'DESC' THEN y.OpenDate END DESC       ) AS RowNumber, 
y.TicketID, 
y.TicketNumber, 
y.AccountID, 
y.SkillID 
FROM (SELECT 
    t.TicketID, 
    t.TicketNumber, 
    t.AccountID, 
    t.SkillID FROM someTable t) AS y 

) AS x WHERE x.RowNumber BETWEEN @startIdx AND @endIdx 

请注意我ommitted某些领域，缩短查询。这可以正常工作，并且在调用该过程时，结果集将返回正确排序。现在我需要向结果集添加一条附加记录。我尝试了联合查询，但由于某些原因，它打破了排序，结果集总是以相同的顺序返回...

SELECT x.TicketID, 
x.TicketNumber, 
x.AccountID, 
x.SkillID 
FROM (
SELECT ROW_NUMBER() OVER(ORDER BY 
    CASE WHEN @ipv_SortExpression = 'TicketNumber' AND @ipv_SortDirection = 'ASC' THEN y.TicketNumber END ASC, 
    CASE WHEN @ipv_SortExpression = 'TicketNumber' AND @ipv_SortDirection = 'DESC' THEN y.TicketNumber END DESC,    
    CASE WHEN @ipv_SortExpression = 'AccountNumber' AND @ipv_SortDirection = 'ASC' THEN y.AccountNumber END ASC, 
    CASE WHEN @ipv_SortExpression = 'AccountNumber' AND @ipv_SortDirection = 'DESC' THEN y.AccountNumber END DESC,    
    CASE WHEN @ipv_SortExpression = 'OpenDate' AND @ipv_SortDirection = 'ASC' THEN y.OpenDate END ASC, 
    CASE WHEN @ipv_SortExpression = 'OpenDate' AND @ipv_SortDirection = 'DESC' THEN y.OpenDate END DESC       ) AS RowNumber, 
y.TicketID, 
y.TicketNumber, 
y.AccountID, 
y.SkillID 
FROM (SELECT 
    t.TicketID, 
    t.TicketNumber, 
    t.AccountID, 
    t.SkillID FROM someTable t) AS y 

) AS x WHERE x.RowNumber BETWEEN @startIdx AND @endIdx 
    UNION 
SELECT 
    z.TicketID 
    z.TicketNumber 
    z.AccountID 
    z.SkillID 
FROM (

SELECT TOP 1 
    tix.biTicketID as TicketID 
    , tix.vcTicketID as TicketNumber 
    , tix.biAccountID as AccountID 
    , tix.siSkillID as SkillID 
FROM someOtherTable tix ORDER BY tix.ActionDate) As z 

此查询断裂排序我的网格。这就像程序完全忽略了我传入的排序标准。我试图先放置较小的查询，然后联合较大的查询，但仍然没有运气。任何人都可以看到我做错了什么，或者我可以如何补救？客户想要这个新功能，但他们不想牺牲排序。我如何正确完成我的任务？感谢任何建议或提示的一堆。

〜CK你需要一个ORDER BY对整个结果，如果你想要的结果进行排序集合。

(Query A) 
UNION 
(Query B) 
ORDER BY xxx
