我正在研究一个需要 INSERT INTO 和 WHERE 逻辑的触发器。
我有三张桌子。
缺席表:
-----------------------------
| user_id | absence_reason |
-----------------------------
| 1234567 | 40 |
| 1234567 | 50 |
| 1213 | 40 |
| 1314 | 20 |
| 1111 | 20 |
-----------------------------
公司表:
-----------------------------
| user_id | company_id |
-----------------------------
| 1234567 | 10201 |
| 1213 | 10200 |
| 1314 | 10202 |
| 1111 | 10200 |
-----------------------------
就业表:
--------------------------------------
| user_id | emp_type | emp_no |
--------------------------------------
| 1234567 | Int | 1 |
| 1213 | Int | 2 |
| 1314 | Int | 3 |
| 1111 | Ext | 4 |
--------------------------------------
最后我列出了只有emp_type = Int inemployment_table 和company_id = 10200 的数据应该去哪里的表格
出去:
--------------------------------
| employee_id | absence_reason |
--------------------------------
| 1 | 40 |
| 1 | 50 |
| 2 | 40 |
| 3 | 20 |
--------------------------------
这是我的触发器:
CREATE OR REPLACE TRIGGER "INOUT"."ABSENCE_TRIGGER"
AFTER INSERT ON absence_table
FOR EACH ROW
DECLARE
BEGIN
CASE
WHEN INSERTING THEN
INSERT INTO out (absence_reason, employee_id)
VALUES (:NEW.absence_reason, (SELECT employee_id FROM employment_table WHERE user_id = :NEW.user_id)
WHERE user_id IN
(SELECT user_id FROM employment_table WHERE employment_type = 'INT')
AND user_id IN
(SELECT user_id FROM company_table WHERE company_id = '10200');
END CASE;
END absence_trigger;
它显然不起作用,我不知道该怎么做才能使它起作用。有什么建议么?
