Hi All,
I need to set up a kind of identity insert that gives an output in the format: 00001, 00002, 00003 etc. Is there a formatting option for this sort of output using normal identity insert features or do I need to write a function to insert these values (perhaps as text) each time a new record is created?
Sorry if this is really simple but it's only my 4th day in this job!
Marcha

It will be better if you use IDENTITY column...do all formatting (like padding zeros in the begining) at the front-end level if possible.

Thanks Harsh, I thought of this first of all but the problem I have is that other people wil access the table from their own applications and I really need everyone to see a single unified view of the data without the need for formatting instructions.
Any other ideas?

use a computed column to format the zero padding

create table #table
(
	id	int identity(1,1),
	key_id	as right('00000' + convert(varchar(5), id), 5),
	col	int
)

insert into #table (col)
select	10

select * from #table

/*
id          key_id     col         
----------- ---------- ----------- 
1           00001      10
*/

Use only identity column. If you use front end application, use format function to format the number
