How to check if "fetch" returns Multiple rows

Question

I want to know thru some variable (like %found) if the "fetch" returns multiple rows. How can I do it?
My code:
open      tab1_rec for
     'select fld1 '                ||
     'from     tab1 f '               ||
     'where     f.fld3 = :s1 and '     ||
     'f.fld4 = :s2 and '          ||
     'f.fld5 = 1 '
     using     fld3_in,
          fld4_in;
     fetch     tab1_rec into var1;
-- If MULTIPLE
     if      tab1_rec%multiple
Thanks

Answer 1

If returning more than one row is unusual in some way (that is you are expecting only a single row) then you can do it like:
BEGIN
   SELECT fld1 INTO var1
   FROM tab1 f
   WHERE f.fld3 = fld3_in and
         f.fld4 = fld4_in and
         f.fld5 = 1;
   < Do your processing here >
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      < handle no rows >
   WHEN TOO_MANY_ROWS THEN
      < handle multiple rows >
END;No need for a cursor here. If you are expecting more than one row, and just want to know the count for information purposes, then you have to loop and fetch the records.
