GROUP BY子句中不允许使用SQL Server XML方法

Question

我只是发布一个组,我指定xml数据然后我得到错误GROUP BY子句中不允许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

如果我不能通过cluase指定组中的xml数据,那么还有其他选项....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
                ,h.Options 
                ,h.UpdatedBy
                ,h.ModDate from EditedHourSheet h
                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,
    XMLData.value('(Log/EntryDate)[1]','datetime') as EntryDate,
    --XMLData.value('(Log/SpecialistID)[1]','int') as SpecialistID,
    s.Name,

    WHEN 'rdShippingSales' THEN 'Shipping and Sales'
    WHEN 'rdEOL' THEN 'EOL'

    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执行group by.

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
