Question

我正在尝试在我的存储过程中加入这两个语句。我该怎么做才能获得一个表，以便我可以使用groupBy列。

Select 
  TableA.Name,
  TableB.Occupation,
  'Group1' AS [groupBy]
From
 TableA,
 TableB
Where
 TableA.ID = 1

Select 
  TableA.Name,
  TableB.Occupation,
  'Group2' AS [groupBy]
From
 TableA,
 TableB
Where
 TableB.ID = 10

我的结果应该是这样的

Name    Occupation      GroupBy
David   Doctor          Group1
John    Pilot           Group1
Dwayne  Wrestler        Group2
Axel    RockStar        Group2

更新

Table A

ID Name  Occupation  
1  David Doctor
1  John  Pilot
2  Mike  Clerk


Table B 

ID  Name   Occupation
3   Wayne  Writer
4   Shane  Publisher

10个Dwayne Wrestler 10 Axel Rockstar

Answer 1

您似乎可以使用UNION ALL来获得结果：

Select 
  TableA.Name,
  TableA.Occupation,
  'Group1' AS [groupBy]
From TableA
Where TableA.ID = 1
union all
Select 
  TableB.Name,
  TableB.Occupation,
  'Group2' AS [groupBy]
From TableB
Where TableB.ID = 10

见SQL Fiddle with Demo。 UNION ALL将返回两个查询之间的所有行。如果您认为可能有要删除的重复项，则可以使用UNION。
