What is in the 3rd column? What is the actual data and structure of the table?

What would prevent the 3rd A 4 record from coming in?

Easy to sort out, but best to post some actual data and exact expected results.

Poor planning on your part does not constitute an emergency on my part.

[code]
SELECT d.[Group], d.[Order], d.c1, d.c2, d.c3
FROM (
SELECT [Group], [Order], c1, c2, c3,
ROW_NUMBER() OVER (PARTITION BY [Group] ORDER BY [Order]) AS RecID
FROM t1
) AS d
WHERE d.RecID <= 2[/code]
