Question

我正在尝试将3个不同的管道分隔表合并为一个，以便我可以导出为一个文本文件。每个管道分隔表具有不同的结构。这是我到目前为止所拥有的。当我运行Union Query时，它将按查询2，查询1，查询3进行排序;我确信这是因为每个查询的输出都是在ABC订单上做最后的排序。有没有办法按查询顺序对其进行排序？

 SELECT  qry_Header.HDR  
 from qry_Header

 union

 select qry_GHD_Headers.GHD_Header  
 from qry_GHD_Headers inner join [Coverage ID] ON qry_GHD_Headers.      
 [Coverage ID] = [Coverage ID].[Coverage ID]
 where [Coverage ID].ID = 1

 union


 select 
 [qry_Pipe_Delim].Pipe_Delim 
 FROM qry_Pipe_Delim INNER JOIN [Coverage ID] ON qry_Pipe_Delim.
 [Coverage ID] = [Coverage ID].[Coverage ID]
 where [Coverage ID].ID = 1

输出如下：

 GHD|CA015015HL|TM|F|20150414

我弄清楚了 - 至少是一种有效的解决方法

 SELECT HDR
 FROM(
 SELECT  1, qry_Header.HDR  
 from qry_Header

 union

  select 2, qry_GHD_Headers.GHD_Header  
  from qry_GHD_Headers inner join [Coverage ID] ON qry_GHD_Headers.      
  [Coverage ID] = [Coverage ID].[Coverage ID]
  where [Coverage ID].ID = 1

  union


 select 3,
 [qry_Pipe_Delim].Pipe_Delim 
 FROM qry_Pipe_Delim INNER JOIN [Coverage ID] ON qry_Pipe_Delim.
 [Coverage ID] = [Coverage ID].[Coverage ID]
 where [Coverage ID].ID = 1)

MS Access Union查询按Select语句排序
