Question

我有以下工作查询，以小时为单位计算员工的应计时间，但是我需要将11和14更改为（14＆18）IF manager = 1

这是我当前的代码：

CASE 
WHEN TIMESTAMPDIFF(DAY,hiredate,NOW()) < 1
THEN '0'
WHEN TIMESTAMPDIFF(DAY,hiredate,NOW()) >= 1 AND TIMESTAMPDIFF(MONTH, 
hiredate, NOW()) <= 60
THEN '11'
WHEN TIMESTAMPDIFF(MONTH, hiredate, NOW()) >= 61 AND TIMESTAMPDIFF(MONTH, 
hiredate, NOW()) <= 120
THEN '14'
ELSE '18'    
END AS monthly_Accrual_Level

如何添加额外的变量“ manager = 1”以覆盖以下情况：

当结果= 11，但员工是经理时，将时间设为14
当结果= 14，但员工是经理时，将他的时间设为18

Answer 1

您可以使用“小写”：

CASE
...
WHEN TIMESTAMPDIFF(DAY,hiredate,NOW()) >= 1 AND TIMESTAMPDIFF(MONTH, 
hiredate, NOW()) <= 60
THEN CASE WHEN manager = 1 THEN '14' ELSE '11' END
... —- similar for other manager value
END AS monthly_Accrual_Level

或将条件的每一边添加到WHEN：

CASE
...
WHEN TIMESTAMPDIFF(DAY,hiredate,NOW()) >= 1 AND TIMESTAMPDIFF(MONTH, 
hiredate, NOW()) <= 60
AND manager = 1 THEN '14'
WHEN TIMESTAMPDIFF(DAY,hiredate,NOW()) >= 1 AND TIMESTAMPDIFF(MONTH, 
hiredate, NOW()) <= 60
AND manager != 1 THEN '11'
... —- similar for other manager value
END AS monthly_Accrual_Level

我更喜欢“小写”，因为它可以更准确地抓住您用英语表达的意图，但是请选择您更容易阅读的那个。

感谢波西米亚人的出色帮助！

这是我最终得到的解决方案：

CASE
    WHEN TIMESTAMPDIFF( DAY, hiredate, NOW( ) ) < 1 THEN '0' WHEN TIMESTAMPDIFF( DAY, hiredate, NOW( ) ) >= 1 

        AND TIMESTAMPDIFF( MONTH, hiredate, NOW( ) ) <= 60 AND manager != 1 THEN '11' WHEN TIMESTAMPDIFF( DAY, hiredate, NOW( ) ) >= 1 
        AND TIMESTAMPDIFF( MONTH, hiredate, NOW( ) ) <= 60 AND manager = 1 THEN '14' WHEN TIMESTAMPDIFF( DAY, hiredate, NOW( ) ) >= 1 

        AND TIMESTAMPDIFF( MONTH, hiredate, NOW( ) ) <= 120 AND manager != 1 THEN '14' WHEN TIMESTAMPDIFF( DAY, hiredate, NOW( ) ) >= 1 
        AND TIMESTAMPDIFF( MONTH, hiredate, NOW( ) ) <= 120 AND manager = 1 THEN '18' 
    ELSE '18' 
END AS monthly_Accrual_Level
