ORACLE FORALL介绍(三)
artment_id = depts(j);
-- How many rows were affected by each DELETE statement
FOR i IN depts.FIRST..depts.LAST
LOOP
DBMS_OUTPUT.PUT_LINE('Iteration #' || i || ' deleted ' ||
SQL%BULK_ROWCOUNT(i) || ' rows.');
END LOOP;
END;
/
6、FORALL与BULK COLLECT 一起使用（Using FORALL With BULK COLLECT）
[sql]
CREATE TABLE emp_temp AS SELECT * FROM employees;
DECLARE
TYPE NumList IS TABLE OF NUMBER;
depts NumList := NumList(10,20,30);
TYPE enum_t IS TABLE OF employees.employee_id%TYPE;
TYPE dept_t IS TABLE OF employees.department_id%TYPE;
e_ids enum_t;
d_ids dept_t;
BEGIN
FORALL j IN depts.FIRST..depts.LAST
DELETE FROM emp_temp WHERE department_id = depts(j)
RETURNING employee_id, department_id BULK COLLECT INTO e_ids, d_ids;
DBMS_OUTPUT.PUT_LINE('Deleted ' || SQL%ROWCOUNT || ' rows:');
FOR i IN e_ids.FIRST .. e_ids.LAST
LOOP
DBMS_OUTPUT.PUT_LINE('Employee #' || e_ids(i) || ' from dept #' || d_ids(i));
END LOOP;
END;
