HI,in SP I have this query FOR EXECUTE STATEMENT 'SELECT SUM(CANT) FROM TABLE1 WHERE FIEL1='||:F1||' AND FIEL2='||:F2|| IIF(:pCondition=1,' AND FIEL3='||:F3,'') INTO .. DO .. TABLE1 PK =FIELD1,FIELD2,FIELD3
running the query gives a NATURAL PLAN How to make it use the index? Index is used if I change to: FOR SELECT SUM(CANT) FROM TABLE1 WHERE FIEL1=:F1 AND FIEL2=:F2 AND FIEL3=:F3 INTO .. DO .. but this way I can't use the IIF condition that I need thanks!
