gans79,

Try this untested Sql.


Code:

SELECT A.IND                                       
      ,SUM(A.LG) AS LOSS_GAIN_TOTAL               
  FROM (SELECT CASE WHEN GAIN_LOSS_COLUMN < 0             
                    THEN CHAR('LOSS')             
                    ELSE CHAR('GAIN')
                     END          AS IND 
              ,GAIN_LOSS_COLUMN   AS LG   
          FROM TABLE) A                       
 GROUP BY A.IND                                   
  ;
