我有两张桌子:
CREATE TABLE employee (
employee_id NUMBER(5),
first_name VARCHAR2(20),
last_name VARCHAR2(20),
dept_no NUMBER(2),
salary NUMBER(10));
表员工有值:
(1, 'Dan', 'Morgan', 10, 100000);
(2, 'Helen', 'Lofstrom', 20, 100000);
(3, 'Akiko', 'Toyota', 20, 50000);
(4, 'Jackie', 'Stough', 20, 40000);
(5, 'Richard', 'Foote', 20, 70000);
(6, 'Joe', 'Johnson', 20, 30000);
(7, 'Clark', 'Urling', 20, 90000);
CREATE TABLE bonuses (
employee_id NUMBER, bonus NUMBER DEFAULT 100);
表奖金有价值:
(1,100);
(2,100);
(4,100);
(6,100);
(7,100);
我根据奖金表进行了合并:
MERGE INTO bonuses b
USING (
SELECT employee_id, salary, dept_no
FROM employee
WHERE dept_no =20) e
ON (b.employee_id = e.employee_id)
WHEN MATCHED THEN
UPDATE SET b.bonus = e.salary * 0.1
DELETE WHERE (e.salary < 40000)
WHEN NOT MATCHED THEN
INSERT (b.employee_id, b.bonus)
VALUES (e.employee_id, e.salary * 0.05)
WHERE (e.salary > 40000);
当我 从奖金中选择*;
EMPLOYEE_ID BONUS
------------------
1 100
2 10000
3 2500
4 4000
5 3500
7 9000
我的问题是“employee_id#6的奖金记录在哪里”?
答案 0 :(得分:0)
由DELETE WHERE (e.salary < 40000)
声明删除了吗?
你应该让你的一个条件包括平等。
毕竟有人的工资可能只有40K,就像杰基的一样。
