Thanks Rob and Loyd, I appreciate your help. -----Original Message----- From: Muralidhar Narayana Sent: Tue 8/31/2004 9:12 PM To: midrange-l@xxxxxxxxxxxx Cc: 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
