SQL错误：ORA-06502：PL / SQL：数字或值错误

Question

I am experiencing below error on execution of trigger:

SQL Error: ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "Test.ADD_DUMMY_RULE", line 13


create or replace
TRIGGER "ADD_DUMMY_RULE" 
BEFORE DELETE ON testTable
   FOR EACH ROW
WHEN (
old.product_id != 0
      )
DECLARE
 pcnt  NUMBER(14);

BEGIN
 pcnt := 0;

trig_pkg.rowIndex := trig_pkg.rowIndex + 1;

 -- STORING IMAGE_ID
 trig_pkg.old_image_id := :OLD.image_id;

 IF (trig_pkg.rimage_id IS NOT NULL) THEN
  FOR i IN 1..(trig_pkg.hold_imid_tablsize) LOOP
   IF (trig_pkg.old_image_id = trig_pkg.rimage_id(i)) THEN
    pcnt := pcnt + 1;
   END IF;
  END LOOP;
 END IF;

END;

Please suggest what could be the cause of issue.

Edit

datatypes:

trig_pkg.rowIndex - Number
trig_pkg.rimage_id - IS TABLE OF INTEGER INDEX BY binary_integer;
trig_pkg.hold_imid_tablsize- NUMBER(14)

Answer 1

try to remove the following IF part string

IF (trig_pkg.rimage_id IS NOT NULL) THEN

INDEX BY - Tables do not need to initialized
