Question

应该很简单，但不能使它工作。还看了其他类似的答案。此代码生成报告。有三个主要类别：一般调整，财务费用和坏账。我想要完成的任务......

如果这三列全部都是零，则删除该行。就是这样。

DECLARE @startdate DATETIME
DECLARE @lastdate DATETIME

SET @startdate = '20170701'
SET @lastdate = '20170731'

CREATE TABLE #a 
(
    ClientName VARCHAR(50), 
    JobName VARCHAR(50), 
    JobPartner VARCHAR(40), 
    [Date] DATETIME, 
    GenAdj MONEY, 
    FC MONEY, 
    BadDebt MONEY, 
    nomid INT
)

SELECT 
    C.searchname AS 'CLIENT NAME',
    n.date AS 'DATE',
    SUM(CASE WHEN NOMTYPEID=3 AND NOMSUBTYPEID=2 THEN TOTAL else 0 END) AS 'GENERAL ADJUSTMENTS',
    SUM(CASE WHEN NOMTYPEID=3 AND NOMSUBTYPEID=1 THEN TOTAL else 0 END) AS 'FINANCE CHARGES',
    SUM(CASE WHEN NOMTYPEID=3 AND NOMSUBTYPEID=0 THEN TOTAL else 0 END) AS 'BAD DEBTS',
    sl.serviceline AS 'DEPARTMENT',
    p.name AS 'PARTNER NAME'
FROM 
    tblNominal N
JOIN 
    tblNominalAccs A ON N.ContNominalID = A.NominalID
JOIN
    tblclient C on N.clientid = C.clientid
LEFT JOIN 
    tbljob j ON n.jobid = j.JobID
LEFT JOIN 
    tblpartner p ON j.PartnerID = p.PartnerID
LEFT JOIN 
    tbljobtype jt ON j.jobtypeid = jt.jobtypeid 
LEFT JOIN 
    tblserviceline sl ON j.servicelineid = sl.servicelineid
WHERE 
    Date >= @startdate AND DATE <= @LASTDATE
GROUP BY 
    C.searchname, n.date, sl.serviceline, p.name
ORDER BY 
    'CLIENT NAME' asc, 'FINANCE CHARGES' asc

DROP TABLE #a

我想我可能会过度思考这个问题。如何删除全零的行？

感谢您的阅读。

您需要在HAVING后GROUP BY之前使用ORDER BY条款：

HAVING SUM(CASE WHEN NOMTYPEID=3 AND NOMSUBTYPEID=2 THEN TOTAL else 0 END) > 0
    OR SUM(CASE WHEN NOMTYPEID=3 AND NOMSUBTYPEID=1 THEN TOTAL else 0 END) > 0
    OR SUM(CASE WHEN NOMTYPEID=3 AND NOMSUBTYPEID=0 THEN TOTAL else 0 END) > 0

HAVING有点像小组结果的WHERE。
