Example Code

Input Code

IS
    is_open_attr BOOLEAN;
    found_attr BOOLEAN;
    my_record table1%ROWTYPE;
    CURSOR my_cursor IS SELECT * FROM table1;
BEGIN
    OPEN my_cursor;
    LOOP
        FETCH my_cursor INTO my_record;
        EXIT WHEN my_cursor%NOTFOUND;
        is_open_attr := my_cursor%ISOPEN;
        found_attr := my_cursor%FOUND;
    END LOOP;
    CLOSE my_cursor;
END;
