Sql 使用XML字符串更新记录时出错

我在使用XML更新列时出错，但不知道问题出在哪里。请引导我摆脱它。。 这是存储过程代码的一部分

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('(PearticularID)[1]', 'int') AS 'ParticularID',
                NDS.DT.value('(Description)[1]', 'varchar(200)') AS 'Description',
                NDS.DT.value('(SubmitAmount)[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('(ApprovedBy)[1]', 'int') AS 'ApprovedBy',                 
                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.ApprovedBy,
                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.                   ApprovedBy,x.ApprovedDate);
END 

这是我的XML脚本

<NewDataSet>
  <DataTable>
    <ClaimExpenseID>14</ClaimExpenseID>
    <ClaimID>10</ClaimID>

   <RowInfo>UNCHANGED</RowInfo>
   <TableRowIndex>1</TableRowIndex>
 </DataTable>

当我运行这个脚本时，它为SpecialId和SubmittedAmount存储NULL。

将PearticulaId更改为SpecialId，SubmittedAmount更改为SubmittedAmount
