You are looking for a "UNION"


SELECT [GROUP] AS 'Group',
               [ID]           AS 'Id'
FROM dbo.Table1
UNION 
SELECT [SectionGroup] AS 'Group',
               [PartID]             AS 'Id'
FROM dbo.Table2;

Just fyi, you don't need the column names on the second(+) query in a UNION, SQL uses the names from the first query.  This is fine:


SELECT [GROUP] AS 'Group',[ID] AS 'Id'

FROM dbo.Table1

UION

SELECT [SectionGroup], [PartId]

FROM dbo.Table2
