  There's lots of ways, this should work

  declare @s-2 varchar(20)

  set @s-2='008EE'

  --set @s-2='05TT'

  --set @s-2='000RTG'

  --set @s-2='0GG'

  select substring(@s,patindex('%[^0]%',@s),len(@s))

  Thanks a lot..

  it works fine for all the string ..but doesn't work for 0000 string

  it only removes one 0

  I want to make it single 0 if it is more than one 0

  declare @s-2 varchar(20)

  set @s-2='00000'

  select substring(@s,patindex('%[^0]%',@s),len(@s)) as strg

  Is this what you need?

  IF Len(REPLACE(@s,'0','' )) > 0

  select substring(@s,patindex('%[^0]%',@s),len(@s))

  ELSE

  SELECT LEN(REPLACE(@s,'0','' ))

  If everything seems to be going well, you have obviously overlooked something.
