Question

请帮我计算一下我的查询返回的行数，显示一些工作在特定月份的员工。

我的总时数，模式和时间员工姓名，但我如何返回当月工作的确切员工数量？

Count(DISTINCT LD.Employee)显示每位员工出现一次，但如何添加1来获得52作为我的最终答案？

SELECT LD.Period, LD.EmOrg, LD.EmType, LD.Employee, 
    Sum(LD.RegHrs) AS 'Total Hours', Count(LD.RegHrs) AS 'Mode', 
    Count(DISTINCT LD.Employee) AS 'Counted Employees'
FROM SSI.dbo.LD LD
GROUP BY LD.Employee, LD.Period, LD.EmOrg, LD.EmType
HAVING (LD.EmOrg Like '%T00') AND (LD.EmType='S')

数据：

Answer 1

如果您需要员工总数，则需要删除GROUP BY LD.Employee子句。

这就是为什么你的COUNT( LD.Employee )永远是一个。请尝试删除GROUP

算DISTINCT员工
