RE: SQL doubt

Something like this should work:

Replace
YEUXFILE.PQTY-COALESCE(YODIAC.PQTY,0) AS PQTY 

With
YEUXFILE.PQTY - CASE WHEN YODIAC.PQTY > 0 OR YODIAC.PQTY IS NULL THEN
COALESCE(YODIAC.PQTY,0) ELSE YODIAC.PQTY END AS PQTY

HTH,

Subject: SQL doubt

Below is my SQL. I have to do a small modification,

I have to execute this 'YEUXFILE.PQTY-COALESCE(YODIAC.PQTY,0) ' only when
YEUXFILE.PQTY is positive value. (ie. when YEUXFILE.PQTY is greater than or
equal to zero, I have to do that substraction)

Can some one help me to implement this in my already existing solution. I
tried but could not succeed.

Thanks for your help, I sincerely appreciate your help.

 

 

 

 

SELECT YEUXFILE.PRECID,YEUXFILE.CFTC,                    

      YEUXFILE.PEXCH,YEUXFILE.PFC,YEUXFILE.ACCOUNT,              

      YEUXFILE.PFIRM,YEUXFILE.PSNAME,YEUXFILE.PQTY-COALESCE(YODIAC.PQTY,0)


      AS PQTY


      FROM QS36F/YEUXFILE


      LEFT OUTER JOIN (SELECT


      PRECID,ACCOUNT,PFIRM,PFC,SUM(COALESCE(YODIAC.PQTY,           

      0)) AS


       PQTY


      FROM  QS36F/YODIAC GROUP BY PRECID,ACCOUNT,PFIRM,PFC)        

      AS


      YODIAC


      ON YEUXFILE.ACCOUNT = YODIAC.ACCOUNT
