触发器内部错误。 PLS-00201：必须声明标识符“ mySchema.Myfunction”。 甲骨文

Question

I wrote trigger on oracle. I have error when i try to invoke function inside trigger: error PLS-00201: identifier 'mySchema.Myfunction' must be declared. Can somoeone show me how should i declare it? Thanks.

create or replace 
trigger myTrigger
 BEFORE INSERT OR UPDATE OF name_of_A ON schema_A.myTable
 FOR EACH ROW
DECLARE
  A                   varchar2(10);
BEGIN
  A := :new.name_of_A;
  IF A IS NOT NULL THEN
    :new.name_of_A := schema_B.Myfunction( A);
  END IF;
END;

---

Solution:

Added script on schema_a:

grant execute on myfunction to schema_a;

Also changed

:new.name_of_A := schema_B.Myfunction( A);

Into:

:new.name_of_A := MYFUNCTION( A);

And it works. Thanks for help!

Answer 1

Connect as schema_b

SQL> conn schema_b/password

Then grant the necessary privilege:

SQL> grant execute on myfunction to schema_a;

Now schema_a should be able to compile its triggers.
