sql-server - GROUP BY 子句中不允许使用 SQL Server XML 方法

Question

我只是在指定 xml 数据的地方发出一个组，然后我得到错误 GROUP BY 子句中不允许使用 XML 方法。

这是我的sql

SELECT HourSheetID,(MAX(RowID)+1) as "RowID",
XMLData.value('(Log/EntryDate)[1]','datetime') as EntryDate,
XMLData.value('(Log/SpecialistID)[1]','int') as SpecialistID,
XMLData.value('(Log/HoursData)[1]','decimal(18,2)') as HoursData,
XMLData.value('(Log/UpdatedBy)[1]','varchar(max)') as UpdatedBy,
XMLData.value('(Log/Options)[1]','varchar(max)') as Options,
logdate
FROM  dbo.EditedHourSheetLog
GROUP BY HourSheetID,
XMLData.value('(Log/EntryDate)[1]','datetime'),
XMLData.value('(Log/SpecialistID)[1]','int'),
XMLData.value('(Log/HoursData)[1]','decimal(18,2)'),
XMLData.value('(Log/UpdatedBy)[1]','varchar(max)'),
XMLData.value('(Log/Options)[1]','varchar(max)'),
logdate

如果我不能按条款在组中指定 xml 数据，那么还有什么其他选项可用....请指导。谢谢

这样我就完成了我的任务

ALTER PROC sp_HourSheetLog
(
    @StartDate VARCHAR(8),
    @EndDate VARCHAR(8)
)
AS

SELECT B.ID
    ,A.RowID
    ,B.EntryDate
    ,B.Name
    ,B.HoursData
    ,B.UpdatedBy
    ,Options=(CASE B.Options
    WHEN 'rdLeave' THEN 'Leave'
    WHEN 'rdsick' THEN 'Sick'
    WHEN 'rdSalvage' THEN 'Salvage'
    WHEN 'rdCSRDuty' THEN 'CSR Duty'
    WHEN 'rdShippingSales' THEN 'Shipping and Sales'
    WHEN 'rdEOL' THEN 'EOL'
    WHEN 'rdTraining' THEN 'Training'
    WHEN 'rdOther' THEN 'Other'
    END)
    ,B.ModDate
        FROM (
        (
            SELECT HourSheetID,(MAX(RowID)+1) as "RowID"
            FROM EditedHourSheetLog l,EditedHourSheet h
            GROUP BY HourSheetID
        ) A
        JOIN
        (
            SELECT h.ID
                ,s.Name
                ,h.EntryDate
                ,h.HoursData

                LEFT JOIN Specialists s
                ON h.SpecialistID=s.SpecialistID
        ) B
    ON A.HourSheetID=B.ID
    )
    WHERE Convert(Varchar,ModDate,112)>=@StartDate AND
    Convert(Varchar,ModDate,112)<=@EndDate


UNION

    Select HourSheetID as ID,RowID,

    END),
    LogDate as ModDate
    FROM EditedHourSheetLog h
    LEFT JOIN Specialists s
    ON h.XMLData.value('(Log/SpecialistID)[1]','int')=s.SpecialistID
    WHERE Convert(Varchar,LogDate,112)>=@StartDate AND
    Convert(Varchar,LogDate,112)<=@EndDate

)
ORDER BY ID,RowID DESC

--sp_HourSheetLog '20140101','20140326'

您可以使用派生表并在主查询中进行分组。

SELECT T.HourSheetID,
       MAX(T.RowID)+1 as RowID,
       T.EntryDate,
       T.SpecialistID,
       T.HoursData,
       T.UpdatedBy,
       T.Options,
       T.logdate
FROM (
     SELECT HourSheetID,
            RowID,
            XMLData.value('(Log/EntryDate)[1]','datetime') as EntryDate,
            XMLData.value('(Log/SpecialistID)[1]','int') as SpecialistID,
            XMLData.value('(Log/HoursData)[1]','decimal(18,2)') as HoursData,
            XMLData.value('(Log/UpdatedBy)[1]','varchar(max)') as UpdatedBy,
            XMLData.value('(Log/Options)[1]','varchar(max)') as Options,
            logdate
     FROM  dbo.EditedHourSheetLog
     ) AS T
GROUP BY T.HourSheetID,
         T.EntryDate,
         T.SpecialistID,
         T.HoursData,
         T.UpdatedBy,
         T.Options,
         T.logdate
