  ya i could get my solution as

  select

  ZZ.gid,

  ZZ.Record1 as 'OldRecord1',

  CASE WHEN XX.Record1 IS NULL THEN 'No New Record' ELSE XX.Record1 END as 'NewRecord1' ,

  ZZ.Record2 as 'OldRecord2',

  CASE WHEN XX.Record2 IS NULL THEN 'No New Record' ELSE XX.Record2 END as 'NewRecord2'

  --XX.Record1 as 'NewRecord1',

  --XX.Record2 as 'NewRecord2'

  from

  (

  SELECT

  ROW_NUMBER ( ) OVER ( order by id )as RN,gid,Record1,Record2 from tblName

  where Level=0

  )ZZ left outer join

  (

  SELECT

  ROW_NUMBER ( ) OVER ( order by id )as RNN,

  Record1,

  Record2

  from tblName

  where Level=1

  )XX on xx.rnn=zz.rn
