Question

我有一个XML文件数据，如下所示。

'<NewDataSet>
  <tblVCWS_Schedule>
    <PKWSSchedule>1</PKWSSchedule>    
    <ScheduleTime>PT7H</ScheduleTime>    
  </tblVCWS_Schedule>
  <tblVCWS_Schedule>
    <PKWSSchedule>2</PKWSSchedule>   
    <ScheduleTime>PT13H30M</ScheduleTime>    
  </tblVCWS_Schedule>
  <tblVCWS_Schedule>
    <PKWSSchedule>3</PKWSSchedule>    
    <ScheduleTime>PT13H30M</ScheduleTime>    
  </tblVCWS_Schedule> 
</NewDataSet>'

ScheduleTime字段是SQL中的time（7）数据类型字段。

但是当我尝试将数据保存到临时表中时，我得到了

“从字符串转换日期和/或时间时转换失败”

 DECLARE @PreAdviceSubmissions  varchar(max) 

    set @PreAdviceSubmissions=
    '<NewDataSet>
      <tblVCWS_Schedule>
        <PKWSSchedule>1</PKWSSchedule>    
        <ScheduleTime>PT7H</ScheduleTime>    
      </tblVCWS_Schedule>
      <tblVCWS_Schedule>
        <PKWSSchedule>2</PKWSSchedule>   
        <ScheduleTime>PT13H30M</ScheduleTime>    
      </tblVCWS_Schedule>
      <tblVCWS_Schedule>
        <PKWSSchedule>3</PKWSSchedule>    
        <ScheduleTime>PT13H30M</ScheduleTime>    
      </tblVCWS_Schedule> 
    </NewDataSet>'

    DECLARE @hDoc int

        CREATE TABLE #PreAdviceSubmissions
        (   
           PKWSSchedule bigint,
           ScheduleTime Time(7)
        )

        EXECUTE sp_xml_preparedocument @hDoc OUTPUT, @PreAdviceSubmissions

        INSERT INTO #PreAdviceSubmissions 
        (
           PKWSSchedule,
           ScheduleTime
        )
        SELECT 
           PKWSSchedule ,
           CAST(ScheduleTime AS TIME(7)) 
        FROM OPENXML(@hDoc,'/NewDataSet/tblVCWS_Schedule', 2)
        WITH 
        (
            PKWSSchedule  bigint 'PKWSSchedule' ,   
            ScheduleTime  Time(7) 'ScheduleTime'          
        )

        EXECUTE sp_xml_removedocument @hDoc

        select * from #PreAdviceSubmissions

任何人都可以帮忙解决这个问题吗？请注意，我无法将数据类型Time（7）更改为任何其他数据类型。

Answer 1

试试这个

    INSERT INTO #PreAdviceSubmissions 
    (
       PKWSSchedule,
       ScheduleTime
    )
    SELECT 
       PKWSSchedule ,
       CASE WHEN (SELECT CHARINDEX('%M%',ScheduleTime)) > 0 THEN 
       CONVERT(time(7),REPLACE(REPLACE(REPLACE(ScheduleTime,'PT',''),'H',':'),'M',''))
       ELSE
       CONVERT(time(7),REPLACE(REPLACE(ScheduleTime,'PT',''),'H',':00')) END
    FROM OPENXML(@hDoc,'/NewDataSet/tblVCWS_Schedule', 2)
    WITH 
    (
        PKWSSchedule  bigint 'PKWSSchedule' ,   
        ScheduleTime  Time(7) 'ScheduleTime'          
    )

Answer 2

DECLARE @TIME VARCHAR(50) = 'PT13H30M'

IF (SELECT PATINDEX('%M%','@TIME') > 0)
BEGIN
    SELECT CONVERT(TIME,REPLACE(REPLACE(REPLACE(@TIME,'PT',''),'H',':'),'M',''))
END
ELSE
BEGIN
    SELECT CONVERT(TIME,REPLACE(REPLACE(@TIME,'PT',''),'H',':00'))
END

从字符串转换日期和/或时间时转换失败（当尝试保存XML数据时）
