%ROWCOUNT
When its cursor or cursor variable is opened, the %ROWCOUNT is zeroed. Before the first fetch, the %ROWCOUNT yields 0. Afterward, it yields the number of rows fetched so far. The number is incremented if the final fetch returned a row. In the next illustration, you can use the %ROWCOUNT to take action if more than ten rows have been fetched:
LOOP
FETCH c1 INTO my_ename, my_deptno;
IF c1%ROWCOUNT > 10 THEN
...
END IF;
END LOOP;
When a cursor or cursor variable is not open, referencing it with the %ROWCOUNT raises the
INVALID_CURSOR.
