sql – 从第二个日期范围开始加入两个表日期

2019年8月4日 192次阅读

我有两个表如下(日期格式：yyyy-MM-dd)：

1)表1 – EMPLOYEE_OVERTIMES(别名：EO)

EMPLOYEE_ID | OVERTIME_DATE
------------------------------------------------
1           | 2012-04-01
2           | 2012-08-14
3           | 2012-07-22
4           | 2012-10-30
5           | 2012-06-07

2)表2 – EMPLOYEE_HOLIDAYS(别名：EH)

EMPLOYEE_ID | START_DATE | END_DATE   |
-----------------------------------------
1           | 2012-03-28 | 2012-04-10
2           | 2012-01-14 | 2012-01-30
3           | 2012-07-15 | 2012-07-25
4           | 2012-10-10 | 2012-10-13
5           | 2012-06-01 | 2012-06-07

表EMPLOYEE_OVERTIMES和EMPLOYEE_HOLIDAYS从其他表连接.我想找到符合以下条件的所有记录：
EH.START_DATE< = EO.OVERTIME_DATE< = EH.END_DATE 3)结果表

EMPLOYEE_ID | START_DATE | END_DATE   | OVERTIME_DATE
-------------------------------------------------------
1           | 2012-03-28 | 2012-04-10 | 2012-04-01
3           | 2012-07-15 | 2012-07-25 | 2012-07-22
5           | 2012-06-01 | 2012-06-07 | 2012-06-07

SELECT EH.*, EO.OVERTIME_DATE 
FROM EMPLOYEE_HOLIDAYS EH
JOIN EMPLOYEE_OVERTIMES EO
ON (EO.EMPLOYEE_ID = EH.EMPLOYEE_ID) AND 
   (EO.OVERTIME_DATE BETWEEN EH.START_DATE AND EH.END_DATE)
