oracle insert两个关联表

现有一张老师学生表(tb_tea_cou)，由于业务需要，需把老师学生表tb_tea_stu拆分成两张表(tb_tea、tb_cou)，并把记录insert到这两张子表中(tb_tea、tb_cou为关联的两张表)。

表结构如下：
tb_tea_cou(
   id, //pk
   name, //任课老师
   zc, //职称
   course //课程
)，

老师表：
tb_tea(
   tid, //pk
   tname, //任课老师
   zc //职称
)，

课程表：
tb_cou(
   cid, //pk
   course, //课程
   tea_id //fk，tb_tea id
)

插入数据

INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '张三', '教师', '语文');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '李四', '教师', '数学');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '王五', '教师', '英语');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '老刘', '教师', '历史');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '小王', '教师', '政治');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '杜甫', '教师', '生物');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '李白', '教师', '化学');
INSERT INTO tb_tea_cou (ID, name, zc, course) VALUES (hibernate_seq.nextval, '韩愈', '教师', '物理');
select * from tb_tea_cou;

 

思路，使用存储过程，插入tb_tea表之后，select max(tid) from tb_tea; 得到刚刚插入的序列的最大值，在后面将这个值插入tb_cou表中。

--创建存储过程
SET serveroutput ON;
CREATE OR REPLACE PROCEDURE proce_insert_tab(error_msg OUT VARCHAR2) IS
    v_id NUMBER(9, 2);
BEGIN
    FOR cur IN (select * FROM tb_tea_cou) LOOP
       SELECT hibernate_seq.nextval INTO v_id FROM dual;
       INSERT INTO tb_tea(tid, tname, zc) VALUES (
              v_id, cur.name, cur.zc);
       INSERT INTO tb_cou(cid, course, tea_id) VALUES (
              hibernate_seq.nextval, cur.course, v_id);
       COMMIT;
       error_msg:='添加成功';
    END LOOP;
EXCEPTION 
    WHEN OTHERS THEN ROLLBACK;
    error_msg:='添加失败';
    RAISE_APPLICATION_ERROR(-20010, 'ERROR：插入数据有误！');
END;
/
 
--调用存储过程
var error_msg VARCHAR2(200);
exec proce_insert_tab(:error_msg);   
 
 
SELECT * FROM tb_tea;
SELECT * FROM tb_cou;
SELECT t.tid, t.tname, t.zc, c.course FROM tb_tea t, tb_cou c WHERE t.tid=c.tea_id
delete from tb_tea;
delete from tb_cou;
