[code]SELECT sdate
FROM
(
SELECT *,CASE WHEN [case] in ('a1','a2','a3','a4') then 'group1'
WHEN [case] in ('b1', 'b2', 'b3' ,'b4') then 'group2'
END AS Grouping
FROM sourceTable
)t
GROUP BY sdate
HAVING SUM(case when Grouping = 'Group1' THEN 1 ELSE 0 END) >0
AND SUM(case when Grouping = 'Group2' THEN 1 ELSE 0 END) >0[/code]

thanks for your solution but i want like follows

the following records only should produce

2-jan-2008,b1,30.00
2-jan-2008,a1,12.00

every date should contain atleast one record for every group.
