Need workaround for Oracle Mutating table

Hi there,

I wish to insert two values as 0 if there exists a similar record in the database. Here goes the code for the same.

The trigger is like this:

CREATE OR REPLACE TRIGGER BEFORE_CHANGE_SVM    BEFORE INSERT OR UPDATE
   ON ST_VOL_MNTH
   FOR EACH ROW
REC := RY_CGE(:NEW.X,:NEW.Y,:NEW.Z);
--the function is defined below.

      IF (REC>0) THEN
-set the new value.abc :=0;

      END IF;
END; Where the function is like this. which returns the number of records present in the table matching the criterea,

      SELECT COUNT(*) INTO REC FROM ST_VOL_MNTH SVM    where values are matching.

I'm getting the mutation error as i'm trying to query the same table on which the trigger is written.
It would be great if somebody can help!

Thanks in advance.
