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.

      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
