如何为一个字段设置“0.5”值 - SSMS t-sql

Question

我有以下代码：

DECLARE @MonthBOP date = '07-01-2017'
DECLARE @MonthEOP date = '09-30-2018'
DECLARE @GLRegionsWHID int = 705
DECLARE @GLProgramsWHID int = -1

SELECT 
    glrn.[WHID] as [RegionWHID],
    glrn.Region,
    dol.WHID [DOL Status],
    dol.DOLStatusCode,
    COUNT(DISTINCT tm.PaycomEmployeeFK) AS [CountClients]
FROM 
    [WH].[Fact].[PaycomTimeSheet] tm
INNER JOIN 
    [Dimension].PaycomEmployee empl ON tm.PaycomEmployeeFK = empl.WHID
INNER JOIN 
    [Dimension].PaycomDOLStatus dol ON empl.PaycomDOLStatusFK = dol.WHID
INNER JOIN 
    [Dimension].GLProgram glpgm ON tm.GLProgramFK = glpgm.WHID
INNER JOIN 
    [Dimension].GLRegion glrn ON glpgm.GLRegionFK = glrn.WHID
WHERE 
    (tm.WorkDate >= @MonthBOP) AND (tm.WorkDate <= @MonthEOP)
    AND ((dol.WHID IN (1, 2)))
    AND ((glrn.WHID IN (@GLRegionsWHID)) OR (-1 IN (@GLRegionsWHID)))
    AND ((glpgm.WHID IN (@GLProgramsWHID)) OR (-1 IN (@GLProgramsWHID)))
GROUP BY
    glrn.[WHID], glrn.Region, dol.DOLStatusCode, dol.WHID
ORDER BY
    glrn.Region

结果如下：

它计算全职/兼职员工的独特数量

我的目标是将每个 "Full Time employee" 计为 1（其中 dol.WHID = 1），这是正确的。

但是每个 "Part Time employee" 我需要算作“0.5”（其中 dol.WHID = 2），这是不正确的，因为它仍然算作 "DOLStatus 2" - 1

有什么想法可以实现吗？

谢谢你，一如既往！

Answer 1

好吧，我会使用 case 语句将计数乘以 0.5：

CASE WHEN dol.WHID = 2 THEN 0.5 ELSE 1.0 END * COUNT(DISTINCT tm.PaycomEmployeeFK) AS [CountClients]

Answer 2

您可以将 SUM 与 CASE

一起使用

DECLARE @MonthBOP date = '07-01-2017'
DECLARE @MonthEOP date = '09-30-2018'
DECLARE @GLRegionsWHID int = 705
DECLARE @GLProgramsWHID int = -1

SELECT 
    glrn.[WHID] as [RegionWHID],
    glrn.Region,
    dol.WHID [DOL Status],
    dol.DOLStatusCode,
    SUM(CASE WHEN dol.WHID = 1 THEN 1.00 WHEN dol.WHID = 2 THEN 0.5 END ) AS [CountClients]
FROM 
    [WH].[Fact].[PaycomTimeSheet] tm
INNER JOIN 
    [Dimension].PaycomEmployee empl ON tm.PaycomEmployeeFK = empl.WHID
INNER JOIN 
    [Dimension].PaycomDOLStatus dol ON empl.PaycomDOLStatusFK = dol.WHID
INNER JOIN 
    [Dimension].GLProgram glpgm ON tm.GLProgramFK = glpgm.WHID
INNER JOIN 
    [Dimension].GLRegion glrn ON glpgm.GLRegionFK = glrn.WHID
WHERE 
    (tm.WorkDate >= @MonthBOP) AND (tm.WorkDate <= @MonthEOP)
    AND ((dol.WHID IN (1, 2)))
    AND ((glrn.WHID IN (@GLRegionsWHID)) OR (-1 IN (@GLRegionsWHID)))
    AND ((glpgm.WHID IN (@GLProgramsWHID)) OR (-1 IN (@GLProgramsWHID)))
GROUP BY
    glrn.[WHID], glrn.Region, dol.DOLStatusCode, dol.WHID
ORDER BY
    glrn.Region
