問題描述

我只是通過在其中指定 xml 數據的位置發出一個組，然后出現錯誤 在 GROUP BY 子句中不允許使用 XML 方法.

i just issue a group by where i specify xml data then i got error XML methods are not allowed in a GROUP BY clause.

這是我的 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

如果我不能按條款指定組中的 xml 數據，那么還有什么其他選項可用....請指導.謝謝

if i can not specify xml data in group by cluase then what other option is available....please guide. thanks

推薦答案

您可以使用派生表并在主查詢中進行分組.

You can use a derived table and do the group by in the main query.

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
