我正在使用mysql数据库。我有员工请假表,里面有员工请假的信息。
请查找表格详细信息:
CREATE TABLE IF NOT EXISTS `APPLY_LEAVE` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`EMP_ID` varchar(100) NOT NULL,
`TYPE_OF_LEAVE` varchar(100) NOT NULL,
`DAYS` varchar(100) NOT NULL,
`REASON` varchar(200) NOT NULL,
`START_DATE` date NOT NULL,
`END_DATE` date NOT NULL,
`STATUS` tinyint(2) NOT NULL,
`CREATED_ON` date NOT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;
--
-- Dumping data for table `APPLY_LEAVE`
--
INSERT INTO `APPLY_LEAVE` (`ID`, `EMP_ID`, `TYPE_OF_LEAVE`, `DAYS`, `REASON`, `START_DATE`, `END_DATE`, `STATUS`, `CREATED_ON`) VALUES
(1, 'EMP001', 'SL', '2', 'Sick Leave', '2018-11-30', '2018-12-01', 1,'2018-11-06'),
(2, 'EMP002', 'EL', '1', 'Personal', '2018-12-13', '2018-12-13', 1,'2018-11-09'),
(3, 'EMP003', 'CL', '2', 'Casual Leave due to Birthday', '2018-08-31', '2018-09-01', 1,'2018-08-20'),
(4, 'EMP001', 'CL', '3', 'Casual Leave', '2018-12-04', '2018-12-06', 1,'2018-11-27'),
(5, 'EMP002', 'SL', '4', 'Sick Leave', '2018-09-10', '2018-09-13', 1,'2018-10-04'),
(6, 'EMP003', 'SL', '3', 'Sick Leave', '2018-10-30', '2018-11-01', 1,'2018-11-25');
需要输出:我想生成报表/excel,以根据休假类型接收按月员工休假数据的信息,即(按月,休假类型数据)格式应如下:
要求:我想mysql查询获取附加的结果按月,休假类型的数据(sl/cl/el)的雇员采取。
查询尝试:
SELECT EMP_ID,
SUM(CASE WHEN TYPE_OF_LEAVE = 'EL' AND MONTH( START_DATE ) =11 THEN DAYS ELSE 0 END ) AS EL_NOV,
SUM(CASE WHEN TYPE_OF_LEAVE = 'CL' AND MONTH( START_DATE ) =11 THEN DAYS ELSE 0 END ) AS CL_NOV,
SUM(CASE WHEN TYPE_OF_LEAVE = 'SL' AND MONTH( START_DATE ) =11 THEN DAYS ELSE 0 END ) AS SL_NOV,
SUM(CASE WHEN TYPE_OF_LEAVE = 'LOP' AND MONTH( START_DATE ) =11 THEN DAYS ELSE 0 END ) AS LOP_NOV,
SUM(CASE WHEN TYPE_OF_LEAVE = 'EL' AND MONTH( START_DATE ) =12 THEN DAYS ELSE 0 END ) AS EL_DEC,
SUM(CASE WHEN TYPE_OF_LEAVE = 'CL' AND MONTH( START_DATE ) =12 THEN DAYS ELSE 0 END ) AS CL_DEC,
SUM(CASE WHEN TYPE_OF_LEAVE = 'SL' AND MONTH( START_DATE ) =12 THEN DAYS ELSE 0 END ) AS SL_DEC,
SUM(CASE WHEN TYPE_OF_LEAVE = 'LOP' AND MONTH( START_DATE ) =12 THEN DAYS ELSE 0 END ) AS LOP_DEC
FROM APPLY_LEAVE
GROUP BY EMP_ID
面临的问题:即一名员工在星期五和星期六休假(即emp001在2018-11-30到2018-12-01期间休sl)(星期五是最后一个日期,星期六是每月的第一个日期,我在表中插入一条记录。当员工申请休假时。结果应该是
emp001-sl公司
11月1日休假
12月1日休假
如何编写这个mysql查询?
