我有一個存儲過程中此查詢）：SQL服務器：ORDER BY子句在視圖，內聯函數，派生表無效，子查詢
SELECT *
FROM
dbo.JointHistory c
OUTER APPLY
(SELECT
MAX(CASE NdtType WHEN 'RT' THEN RequestNumber END) AS MasterRTRequestNumber,
MAX(CASE NdtType WHEN 'RT' THEN NdtReportNumber END) AS ContractorRTRequestNumber,
MAX(CASE NdtType WHEN 'RT' THEN ResponseReportNumber END) AS ContractorRTReportNumber,
MAX(CASE NdtType WHEN 'RT' THEN ResponseReportDatetime END) AS RTDate,
MAX(CASE NdtType WHEN 'RT' THEN Defect END) AS RTDefect,
MAX(CASE NdtType WHEN 'RT' THEN Remark END) AS RTSegment,
MAX(CASE NdtType WHEN 'PT' THEN RequestNumber END) AS MasterPTRequestNumber,
MAX(CASE NdtType WHEN 'PT' THEN NdtReportNumber END) AS ContractorPTRequestNumber,
MAX(CASE NdtType WHEN 'PT' THEN ResponseReportNumber END) AS ContractorPTReportNumber,
MAX(CASE NdtType WHEN 'PT' THEN ResponseReportDatetime END) AS PTDate,
MAX(CASE NdtType WHEN 'PT' THEN Defect END) AS PTDefect,
MAX(CASE NdtType WHEN 'PT' THEN Remark END) AS PTSegment,
MAX(CASE NdtType WHEN 'PWHT' THEN RequestNumber END) AS MasterPWHTRequestNumber,
MAX(CASE NdtType WHEN 'PWHT' THEN NdtReportNumber END) AS ContractorPWHTRequestNumber,

MAX(CASE NdtType WHEN 'PWHT' THEN Defect END) AS PWHTDefect,
MAX(CASE NdtType WHEN 'PWHT' THEN Remark END) AS PWHTSegment,
MAX(CASE NdtType WHEN 'MT' THEN RequestNumber END) AS MasterMTRequestNumber,
MAX(CASE NdtType WHEN 'MT' THEN NdtReportNumber END) AS ContractorMTRequestNumber,
MAX(CASE NdtType WHEN 'MT' THEN ResponseReportNumber END) AS ContractorMTReportNumber,
MAX(CASE NdtType WHEN 'MT' THEN ResponseReportDatetime END) AS MTDate,
MAX(CASE NdtType WHEN 'MT' THEN Defect END) AS MTDefect,
MAX(CASE NdtType WHEN 'MT' THEN Remark END) AS MTSegment,
MAX(CASE NdtType WHEN 'UT' THEN RequestNumber END) AS MasterUTRequestNumber,

MAX(CASE NdtType WHEN 'UT' THEN Defect END) AS UTDefect,
MAX(CASE NdtType WHEN 'UT' THEN Remark END) AS UTSegment
FROM
(SELECT TOP 1 WITH TIES
NRD.NdtType, NRD.RequestNumber, NR.NdtReportNumber,
NRD.ResponseReportDatetime, NRD.Defect,
NRD.ResponseReportNumber, NRD.Remark
FROM
dbo.NdtReportDetails NRD
LEFT OUTER JOIN
NdtReports NR ON NRD.ReportId = NR.Id
WHERE
NRD.JointId = c.Id
AND NRD.NdtType IN ('RT', 'PT', 'PWHT', 'MT', 'UT')
ORDER BY
NRD.Id DESC) i) b
但在此基礎上查詢的結尾出現了問題問題:https://stackoverflow.com/questions/41518618/select-top-ties-in-sql-cant-return-expected-data/41518699
所以我的查詢更改爲此：
SELECT *
FROM dbo.JointHistory c
OUTER Apply (SELECT Max(CASE NdtType WHEN 'RT' THEN RequestNumber END) AS MasterRTRequestNumber,
Max(CASE NdtType WHEN 'RT' THEN NdtReportNumber END) AS ContractorRTRequestNumber,
Max(CASE NdtType WHEN 'RT' THEN ResponseReportNumber END) AS ContractorRTReportNumber,
Max(CASE NdtType WHEN 'RT' THEN ResponseReportDatetime END) AS RTDate,
Max(CASE NdtType WHEN 'RT' THEN Defect END) AS RTDefect,
Max(CASE NdtType WHEN 'RT' THEN Remark END) AS RTSegment,
Max(CASE NdtType WHEN 'PT' THEN RequestNumber END) AS MasterPTRequestNumber,
Max(CASE NdtType WHEN 'PT' THEN NdtReportNumber END) AS ContractorPTRequestNumber,
Max(CASE NdtType WHEN 'PT' THEN ResponseReportNumber END) AS ContractorPTReportNumber,
Max(CASE NdtType WHEN 'PT' THEN ResponseReportDatetime END) AS PTDate,
Max(CASE NdtType WHEN 'PT' THEN Defect END) AS PTDefect,
Max(CASE NdtType WHEN 'PT' THEN Remark END) AS PTSegment,
Max(CASE NdtType WHEN 'PWHT' THEN RequestNumber END) AS MasterPWHTRequestNumber,
Max(CASE NdtType WHEN 'PWHT' THEN NdtReportNumber END) AS ContractorPWHTRequestNumber,
Max(CASE NdtType WHEN 'PWHT' THEN ResponseReportNumber END) AS ContractorPWHTReportNumber,
Max(CASE NdtType WHEN 'PWHT' THEN ResponseReportDatetime END) AS PWHTDate,
Max(CASE NdtType WHEN 'PWHT' THEN Defect END) AS PWHTDefect,
Max(CASE NdtType WHEN 'PWHT' THEN Remark END) AS PWHTSegment,
Max(CASE NdtType WHEN 'MT' THEN RequestNumber END) AS MasterMTRequestNumber,
Max(CASE NdtType WHEN 'MT' THEN NdtReportNumber END) AS ContractorMTRequestNumber,
Max(CASE NdtType WHEN 'MT' THEN ResponseReportNumber END) AS ContractorMTReportNumber,
Max(CASE NdtType WHEN 'MT' THEN ResponseReportDatetime END) AS MTDate,
Max(CASE NdtType WHEN 'MT' THEN Defect END) AS MTDefect,
Max(CASE NdtType WHEN 'MT' THEN Remark END) AS MTSegment,
Max(CASE NdtType WHEN 'UT' THEN RequestNumber END) AS MasterUTRequestNumber,
Max(CASE NdtType WHEN 'UT' THEN NdtReportNumber END) AS ContractorUTRequestNumber,
Max(CASE NdtType WHEN 'UT' THEN ResponseReportNumber END) AS ContractorUTReportNumber,
Max(CASE NdtType WHEN 'UT' THEN ResponseReportDatetime END) AS UTDate,
Max(CASE NdtType WHEN 'UT' THEN Defect END) AS UTDefect,
Max(CASE NdtType WHEN 'UT' THEN Remark END) AS UTSegment
FROM (
SELECT t.NdtType,
t.RequestNumber,
t.NdtReportNumber,
t.ResponseReportDatetime,
t.Defect,
t.ResponseReportNumber,
t.Remark
FROM
(
SELECT NRD.NdtType,
NRD.Id,
NRD.RequestNumber,
NR.NdtReportNumber,
NRD.ResponseReportDatetime,
NRD.Defect,
NRD.ResponseReportNumber,
NRD.Remark,
ROW_NUMBER() OVER(PARTITION BY NRD.NdtType ORDER BY NRD.Id DESC) AS rn
FROM dbo.NdtReportDetails NRD
LEFT OUTER JOIN NdtReports NR
ON NRD.ReportId = NR.Id
WHERE NRD.JointId = c.Id AND
NRD.NdtType IN ('RT', 'PT', 'PWHT', 'MT', 'UT')
) t
WHERE t.rn = 1
ORDER BY t.Id DESC
) i)b
正如你可以看到查詢的末尾改變基於上面的問題後，我執行這個查詢，我得到這個錯誤：
Msg 1033, Level 15, State 1, Procedure SPJointHistory, Line 72
The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.
嘗試移動'ORDER BY'到外選擇。如果你仔細想想，在內部select中有一個'order by'是沒有意義的，因爲這個包裝不一定遵守接收到的結果集的順序。 – FDavidov
錯誤信息非常清晰。你有什麼難以理解的部分？ –
@KenWhite我不知道我該怎麼做 –
