Hello,

I am running a Query to return records where two items Item where both selected on thesame date.

Field names are: CPTCOD - values are '94002' and '94003' (these are teh item codes)
                           SCVDAT - is the date Field

The current Query is returning the following results:
SVCDAT                     SVCCOD
02/20/2009      94002
05/06/2009      94002
05/06/2009      94002
05/10/2009      94003
05/01/2009      94003
05/02/2009      94003

When it should be returning NO records as there are no instances where both 94002 and 94003 where selected on the same date.

Thank you!
PROC SQL;
Create table main as
Select distinct l.*
FROM ctemp.Proc20090513 l
 
Where l.CPTCOD in ('94002', '94003')
AND l.SVCDAT in (SELECT l.SVCDAT From ctemp.Proc20090513 l
		WHERE l.CPTCOD in ('94002', '94003')
                  	GROUP BY l.SVCDAT HAVING COUNT(DISTINCT l.CPTCOD) > 1)

so you are looking for records that have both svccode selected on the same day?

the in statement is really an "or" check.

try changing your where clause like this:

Where l.CPTCOD = '94002')
AND l.SVCDAT in (SELECT l.SVCDAT From ctemp.Proc20090513 l
                WHERE l.CPTCOD = '94003' )

the first part will pull any 94002 rows, the second part will pull any 94003 rows and the in will only match when the dates are the same.

Would I get rid of the last statement - GROUP BY l.SVCDAT HAVING COUNT(DISTINCT l.CPTCOD) > 1) ?

-thanks

I am assumming yes, after trying it out.

However I still don't think it is correct...but closer.

I am now getting
02/20/2009      94002
05/06/2009      94002
05/06/2009      94002

I think there should be no results found since these records dont have matcing '94003' codes selected on the same day.

if there where records (which there aren't)I would like to see...
02/20/2009      94002
02/20/2009      94003
05/06/2009      94002
05/06/2009      94003

I am testing against this scenerio as it indicates customers are being double charged....

Thanks,

Is there also a customer number field?  In sql statement, if one customer has 94002 and a different customer has 94003, then you will get results.  If you have a customer identifier change the statment this way:

Where l.CPTCOD = '94002')
AND l.SVCDAT in (SELECT l.SVCDAT From ctemp.Proc20090513 l
                WHERE l.CPTCOD = '94003'  and l.customerid=customerid)

and yes leave off the group by distinct.
