%FOUND
Subsequent to a cursor or cursor variable is opened but before the first fetch, the %FOUND yields NULL. Afterward, it yields TRUE when the last fetch returned a row, or FALSE when the final fetch failed to return a row. In the illustration below, you use %FOUND to select an action:
LOOP
FETCH c1 INTO my_ename, my_sal, my_hiredate;
IF c1%FOUND THEN -- fetch succeeded
...
ELSE -- fetch failed, so exit loop
EXIT;
END IF;
END LOOP;
When the cursor or cursor variable is not open, referencing it with the %FOUND raises the predefined exception INVALID_CURSOR.
