How to check if cursor returns any records in oracle?
I think that it possible only with FETCH
. Try to use
if myCursor%found then
// some body
end if;
But if somebody know another way so correct me.
It's not possible to check if the cursor returns records without opening it.
(see here)
So you can either have some fast query just to see if there are records (using count for example),
Or, you can do it like this:
CREATE OR REPLACE PROCEDURE SP_EMPLOYEE_LOOKUP_BY_EMP_ID
(
IN_USER_ID IN NUMBER,
IN_EMPLOYEE_ID NUMBER,
IN_HC_AS_ON_DATE VARCHAR2,
emp_cursor OUT SYS_REFCURSOR
)
IS
is_found_rec boolean := false;
CURSOR employees IS
SELECT * FROM EMPLOYEE e;
BEGIN
FOR employee IN employees
LOOP
is_found_rec := true;
// do something
END LOOP;
if not is_found_rec then
// do something else
end if;
END;
