Sql 将查询结果分组为一行

我的查询返回4条记录（行），我想将所有这些记录相加为一条记录（行），但不完全确定如何实现这一点

这是我的密码

SELECT 
    Tax + StudentLoans AS 'Net Income Tax', 
    GrossNI,
    CASE 
        WHEN ed.EA_Indicator_CY = 0 
            THEN 0 
        ELSE 
        (
            CASE 
                WHEN    (
                            SELECT SUM(Funding) 
                            FROM PayrollRuns 
                            WHERE PAYEMonth = 12 AND PYear = 2018) > 3000
                        ) 
                    THEN 0 
                ELSE 3000 
            END
        ) 
    END AS 'Employment Allowance',
    SMP AS 'SMP Recovered',
    NICompOnSMP AS 'SMP Comp',
    SPPA + SPPB AS 'SPP Recovered',
    SPPACompensation + SPPBCompensation AS 'SPP COMP',
    SAP AS 'SAP Recovered',
    SAPCompensation,
    SHPP_A + SHPP_B AS 'Shpp Recovered',
    SHPP_A_Compensation + SHPP_B_Compensation AS 'ShPP Comp',
    Apprenticeship_Levy_Due AS 'App Levy'
FROM PayrollRuns pr
CROSS JOIN [Employer Details] ed
WHERE PAYEMonth = 12 AND pr.PYear = 2018 --RunID = '1058'
GROUP BY Tax, StudentLoans, GrossNI, SMP, NICompOnSMP, 
    ed.EA_Indicator_CY,
    SPPACompensation, SPPBCompensation, SAPCompensation, SHPP_A_Compensation,
    SHPP_B_Compensation, SPPA, SPPB, SAP, Apprenticeship_Levy_Due, SHPP_A, 
    SHPP_B, RunID

我附上了查询结果的图片。我要一排的总和。任何帮助都将不胜感激

您必须删除组中所有需要汇总的列。尝试此操作：将获取按RUNID分组并具有不同EA指示符的记录

SELECT SUM(Tax +StudentLoans) AS 'Net Income Tax'
    ,SUm(GrossNI)
    ,CASE 
        WHEN (ed.EA_Indicator_CY) = 0
            THEN 0
        ELSE (
                CASE 
                    WHEN (
                            SELECT SUM(Funding)
                            FROM PayrollRuns
                            WHERE PAYEMonth = 12
                                AND PYear = 2018
                            ) > 3000
                        THEN 0
                    ELSE 3000
                    END
                )
        END AS 'Employment Allowance'
    ,SUM(SMP) AS 'SMP Recovered'
    ,SUM(NICompOnSMP) AS 'SMP Comp'
    ,SUM(SPPA + SPPB) AS 'SPP Recovered'
    ,SUM(SPPACompensation + SPPBCompensation) AS 'SPP COMP'
    ,SUM(SAP) AS 'SAP Recovered'
    ,SUM(SAPCompensation)
    ,SUM(SHPP_A + SHPP_B) AS 'Shpp Recovered'
    ,SUM(SHPP_A_Compensation) + SUM(SHPP_B_Compensation) AS 'ShPP Comp'
    ,Apprenticeship_Levy_Due AS 'App Levy'
FROM PayrollRuns pr
CROSS JOIN [Employer Details] ed
WHERE PAYEMonth = 12
    AND pr.PYear = 2018 --RunID = '1058'
    group by ed.EA_Indicator_CY,RUNID

按如下方式使用Sum（）聚合函数

--如果缺少一列，可以添加它：put sum（column）[column\u alias]

select

sum(mytab.[GrossNI]) [sum_GrossNI],

sum(mytab.[ShPP Comp]) [sum_ShPP Comp],
sum(mytab.[SPP COMP]) [sum_SPP COMP],
sum(mytab.[App Levy]) [sum_App Levy],
sum(mytab.[SAPCompensation])[sum_SAPCompensation]

from(
SELECT 
    Tax + StudentLoans AS 'Net Income Tax', 
    GrossNI,
    CASE 
        WHEN ed.EA_Indicator_CY = 0 THEN 0 ELSE 
        (
            CASE 
                WHEN    (
                            SELECT SUM(Funding) 
                            FROM PayrollRuns 
                            WHERE PAYEMonth = 12 AND PYear = 2018) > 3000
                        ) 
                    THEN 0 
                ELSE 3000 
            END
        ) END AS 'Employment Allowance',
    SMP AS 'SMP Recovered',
    NICompOnSMP AS 'SMP Comp',

左对齐SQL非常难读（和写…）@jarlh我对SQL很陌生，什么是左对齐SQL？他指的是你不使用空格缩进代码。就像我会为你编辑一样。@GeorgeMenoutis哦，好吧，我现在明白你的意思了。这就是我编写所有查询的方式，从未意识到这是一种不好的做法。如果您只想有一行，请从

分组中删除这三行中具有不同值的所有字段。请为您的答案提供一些注释。感谢您的回答，如果我只想让就业津贴成为SELECT语句中的案例返回的值，该怎么办？0或3000？这将是“就业津贴”的总和
