Question

我有一个SQL查询，可以获取员工姓名，家庭商店，工资单ID和工作总时数。以下是查询：

 SELECT Employee_Tb.First_Name + ' ' + Employee_Tb.Last_Name AS Name,
        Employee_Tb.Home_Store_Id, Employee_Tb.Payroll_Id, 
        SUM(Payroll_Hours_Tb.Hours_Worked) AS TotalHours
   FROM Employee_Tb
        INNER JOIN Payroll_Hours_Tb
              ON Employee_Tb.Employee_Id = Payroll_Hours_Tb.Employee_Id
  WHERE (Payroll_Hours_Tb.Work_Date BETWEEN @startdate AND @enddate)
  GROUP BY Employee_Tb.Payroll_Id, Employee_Tb.First_Name, Employee_Tb.Last_Name,
        Employee_Tb.Home_Store_Id
  ORDER BY Employee_Tb.Home_Store_Id

我希望将总小时数分为"Regular Hours"和"OT Hours"正常小时定义为小于＆＃34; 40＆＃34;小时。 OT小时定义为大于＆＃34; 40＆＃34;

Answer 1

您应该可以使用CASE表达式，每个值一个。

而不是SUM(Payroll_Hours_Tb.Hours_Worked)，您可以这样做：

CASE WHEN SUM(Payroll_Hours_Tb.Hours_Worked) > 40.0
    THEN 40.0
    ELSE SUM(Payroll_Hours_Tb.Hours_Worked)
    END AS RegularHours,
CASE WHEN SUM(Payroll_Hours_Tb.Hours_Worked) > 40.0
    THEN SUM(Payroll_Hours_Tb.Hours_Worked) - 40.0
    ELSE 0.0
    END AS Overtime

第一个CASE表达式检查小于40的小时数，如果找到，则在正常时间锁定为40，否则使用小时数（因为它小于40）

第二个CASE表达式检查小于40的小时数，如果找到，则从小时数中减去40，以确定加班时间。

with cte as
(
     SELECT Employee_Tb.First_Name + ' ' + Employee_Tb.Last_Name AS Name,
            Employee_Tb.Home_Store_Id, Employee_Tb.Payroll_Id, 
            SUM(Payroll_Hours_Tb.Hours_Worked) AS TotalHours
       FROM Employee_Tb
            INNER JOIN Payroll_Hours_Tb
                    ON Employee_Tb.Employee_Id = Payroll_Hours_Tb.Employee_Id
      WHERE (Payroll_Hours_Tb.Work_Date BETWEEN @startdate AND @enddate)
      GROUP BY Employee_Tb.Payroll_Id, Employee_Tb.First_Name, Employee_Tb.Last_Name,
            Employee_Tb.Home_Store_Id
      ORDER BY Employee_Tb.Home_Store_Id
)
 SELECT Name, Home_Store_Id, Payroll_Id, TotalHours,
        CASE
             WHEN TotalHours <= 40 THEN TotalHours 
             ELSE 40
         END AS 'Regular',
        CASE
             WHEN TotalHours > 40 THEN TotalHours - 40
             ELSE 0
         END AS 'OT'
    FROM cte
