废话不多说，直接上sql:

UPDATE db_huanjing_GM_YanQing_TEST.dbo.GM_AY_yiqi_copy
SET jiandingriqi = concat (
 Datepart(
  yyyy,
  CAST (
   jiandingriqi AS datetime
  )
 ),
 IIF (
  Datepart(
   mm,
   CAST (
    jiandingriqi AS datetime
   )
  ) > 9,
  concat (
   '年',
   Datepart(
    mm,
    CAST (
     jiandingriqi AS datetime
    )
   )
  ),
  concat (
   '年0',
   Datepart(
    mm,
    CAST (
     jiandingriqi AS datetime
    )
   )
  )
 ),
 IIF (
  Datepart(
   dd,
   CAST (
    jiandingriqi AS datetime
   )
  ) > 9,
  concat (
   '月',
   Datepart(
    dd,
    CAST (
     jiandingriqi AS datetime
    )
   )
  ),
  concat (
   '月0',
   Datepart(
    dd,
    CAST (
     jiandingriqi AS datetime
    )
   )
  )
 ),
 '日'
) where jiandingriqi != '';
