我试图写一个更新日期的查询,只有当我更新组的LINE_CD为50.我会这样做吗？

UPDATE EMPLOYER_ADDL  
SET EMPLOYER_ADDL.GTL_UW_APPRV_DT = EMPLOYER_ADDL.DNTL_UW_APPRV_DT 
WHERE EXISTS
    ( 
      SELECT EMP_PLAN_LINE_INFO.LINE_CD
      FROM EMP_PLAN_LINE_INFO
      Where EMP_PLAN_LINE_INFO.GR_NBR = EMPLOYER_ADDL.GR_NBR and
       EMP_PLAN_LINE_INFO.LINE_CD = 50
     )

我试图找出像这样采用xml的最简单方法:

<Car>
 <Description Model="Ford      ">Blue     </Description>
</Car>

进入这个:

<Car>
  <Description Model="Ford">Blue</Description>
</Car>
