    Hi all,

    create table #temp

    (

    id int

    )

    insert into #temp

    select 0

    insert into #temp

    select 2

    insert into #temp

    select 01234

    select * from #temp

    in the above example why it wont accept 0 as starting number ?

    Because numbers don't have leading zeros. If I'm discussing a rugby match score, I'm not going to say it as 009 to 011. Talking about the number of people in the room, there weren't 0015, there were 15.

    If a leading zero is meaningful, that's not a number, that's a string.
