Hi All.

I have select it works fine. But I would like to modify it to display Active field from dbo.Payments table if one of record with the same Request_Id has Actuve='True'. Now it display only for latest PaidDate. If is it possible how it to do? My code is:


select 
r.Request_Id
,Customer_No
,LName
,FName
,s.Status
,t.EffDate
,t.Active
,Amount
from dbo.Request r
LEFT JOIN
(
SELECT p.*
FROM dbo.Payments p
INNER JOIN (SELECT Request_Id,MAX(PaidDate) AS EffDate
	  FROM dbo.Payments
	  GROUP BY Request_ID) x
ON  p.Request_Id = x.Request_Id
AND p.PaidDate = x.EffDate
)t
ON t.Request_ID = r.Request_ID
Left join dbo.v_Status s
on t.Status_Id = s.Status_Id

Thanks

Thanks for replays.

I would like to have select with latest PaidDate and display Active field from dbo.Payments table if one of record with the same Request_Id has Actuve='True'. Is that possible to get? If yes how it to do?

Thanks.

Hi sodeep. Thanks for replay.

Your code return the same result like I had just for latest PaidDate without Active = 'True'. For instance, I have
Request_Id PaidDate Active
=========================================
3 6/3/2011 FALSE
3 9/20/2011 TRUE
3 12/1/2012 FALSE

As the resalt I would like to get
Request_Id PaidDate Active
=========================================
3 12/1/2012 TRUE

Thanks

But Active is True for 9/20/2011 ?

sound like this then


Select 
r.Request_Id
,Customer_No
,LName
,FName
,s.Status
,t.EffDate
,CASE WHEN ActiveCnt > 0 THEN 'True' ELSE t.Active END
,Amount
from dbo.Request r
LEFT JOIN
(
SELECT p.*
FROM dbo.Payments p
INNER JOIN (SELECT Request_Id,MAX(PaidDate) AS EffDate,
          SUM(CASE WHEN Active = 'true' THEN 1 ELSE 0 END) AS ActiveCnt
	  FROM dbo.Payments
	  GROUP BY Request_ID) x
ON  p.Request_Id = x.Request_Id
AND p.PaidDate = x.EffDate
)t
ON t.Request_ID = r.Request_ID
Left join dbo.v_Status s
on t.Status_Id = s.Status_Id

Hi visakh16. Thanks for replays.

I tried your code. In line

CASE WHEN ActiveCnt > 0 THEN 'True' ELSE 'False' END

ActiveCnt indicate like invalid column name. I tried modify like t.ActiveCtn nothing help. When I run INNER JOIN SELECT itself result looks ok but when I run whole code result not like expected.

Thanks.

You need to explain with proper example and expected output. The output you want is confusing.

Hi visakh16. Thanks for continue help.

I solved the problem by modified the line
SELECT p.*
to
SELECT p.*,EffDate,ActiveCnt

Thanks for help.
