Question

我正在使用XML来插入/更新/删除表中的记录。但是当我插入行时，日期值插入的值比实际值少一个。以下是我的存储过程的代码

IF(@Mode='UPDATE_TABLE')
BEGIN
    ;WITH XmlData AS 
        (
            SELECT
                NDS.DT.value('(ClaimExpenseID)[1]', 'int') AS 'ClaimExpenseID',
                NDS.DT.value('(ClaimID)[1]', 'int') AS 'ClaimID',
                NDS.DT.value('(POrderID)[1]', 'int') AS 'POrderID',
                NDS.DT.value('(SiteID)[1]', 'int') AS 'SiteID',
                NDS.DT.value('(FromDate)[1]', 'datetime') AS 'FromDate',
                NDS.DT.value('(ToDate)[1]', 'datetime') AS 'ToDate',
                NDS.DT.value('(ParticularID)[1]', 'int') AS 'ParticularID',
                NDS.DT.value('(Description)[1]', 'varchar(200)') AS 'Description',
                NDS.DT.value('(SubmittedAmount)[1]', 'int') AS 'SubmittedAmount',
                NDS.DT.value('(CreatedDate)[1]', 'datetime') AS 'CreatedDate',
                NDS.DT.value('(ApprovedAmount)[1]', 'int') AS 'ApprovedAmount',
                NDS.DT.value('(ApprovedDate)[1]', 'datetime') AS 'ApprovedDate',
                NDS.DT.value('(Remark)[1]', 'varchar(300)') AS 'Remark',
                NDS.DT.value('(ApproveBy)[1]', 'int') AS 'ApproveBy',                   
                NDS.DT.value('(RowInfo)[1]', 'varchar(20)') AS 'RowInfo'

            FROM 
                @xmlString.nodes('/NewDataSet/DataTable') AS NDS(DT)

        )

        MERGE INTO dbo.ClaimExpenseTRS CET
        USING XmlData x ON CET.ClaimExpenseID = x.ClaimExpenseID
        WHEN MATCHED AND x.RowInfo = 'UPDATE'
           THEN 
             UPDATE SET 
                CET.ClaimID=x.ClaimID,  
                CET.CreatedDate=x.CreatedDate,
                CET.POrderID=x.POrderID,
                CET.SiteID=x.SiteID,
                CET.FromDate=x.FromDate,
                CET.ToDate=x.ToDate,
                CET.ParticularID=x.ParticularID,
                CET.Description=x.Description,
                CET.SubmittedAmount=x.SubmittedAmount,
                CET.ApprovedAmount=x.ApprovedAmount,
                CET.Remarks=x.Remark,
                CET.ApproveBy=x.ApproveBy,
                CET.ApprovedDate=x.ApprovedDate

      WHEN MATCHED AND x.RowInfo = 'DELETE'AND CET.ClaimExpenseID = x.ClaimExpenseID
           THEN DELETE 

        WHEN NOT MATCHED AND x.RowInfo = 'NEW'
           THEN 
              INSERT(ClaimID, CreatedDate, POrderID, SiteID,FromDate,ToDate,ParticularID,                 Description,SubmittedAmount,ApprovedAmount,Remarks,ApproveBy,ApprovedDate)
              VALUES(x.ClaimID,x.CreatedDate,x.POrderID,x.SiteID,x.FromDate,x.ToDate,x. 
              ParticularID,x.Description,x.SubmittedAmount,x.ApprovedAmount,x.Remark,x.                   ApproveBy,x.ApprovedDate);
END

这是XML字符串..

<NewDataSet>
  <DataTable>
     <ClaimExpenseID>5</ClaimExpenseID>
     <ClaimID>1</ClaimID>
     <CreatedDate>2011-08-01T00:00:00+05:30</CreatedDate>

在第二个数据表中，起始日期值为2011-09-22，日期值为2011-09-30但是当数据库表中插入的值分别变为2011-09-21和2011-09-29 ..

Answer 1

这可能是你的+5：30时区吗？这与您的数据库是一样的，还是您的数据库试图计算出不同时区的时间并提前一天？

编辑：我刚刚证实了这一点。如果我将您的日期时间2011-09-30T00:00:00+05:30读入我的机器（位于英国），我会收到2011-09-29 18:30:00.000

的回复

我用于转换的代码是：

select cast('' as xml).value('xs:dateTime("2011-09-30T00:00:00+05:30")', 'datetime')

存储过程在XML字符串中插入比实际日期少一个的日期值
