You can, but you need a subqeury to do it and it is inefficient (uses aggregates).

create table MyCount( MyKEy int, MyVal char( 3))

go

insert MyCount select 4, 'ABC'

insert MyCount select 5, 'DEF'

insert MyCount select 7, 'GHI'

insert MyCount select 12, 'JKL'

insert MyCount select 9, 'MNO'

insert MyCount select 6, 'PQR'

go

select

m.MyKey

, m.MyVal

, (select count(*) 'seq'

from MyCount b

where b.MyKey <= m.MyKey

) 'seq'

from MyCount m

order by m.MyKey

You are welcome. Credit actually goes to Mr Itzak Ben-Gan and Tom Moreau. I learned this trick from their "Advanced T-SQL" book.

Hi,

I need quite the same ability to count the rows, but unfortunately, since my SQL is dynamically generated, can't rely on the fact that I will have a nice MyKey (int) column so I can sort by and make the < condition in the inner query.

Is there any option to get general row counter, regardless the query I run ?

e.g.

result

-----

1

2

3

4

5

Not that I know of. You could insert everything into a temp table with a counter and go from there.

I don't know of a generic way for any query but on a case-by-case basis, you can create a table valued user-defined function with an identity column as one of its output columns. set it to start at 1 and increment by one.

It would really be a nice addition to SQL Server.
