Hi Jamie,

is it ASP ???

you could do something like

select count(*) from tbl, sort of thing

randomize
count = {count varable from select (*)}
random_number=i nt(rnd*count)+1

select from tbl where id = random_number

something like this will do it

The question is what kind of database ? Some databases actually
have a way of doing it directly, if it's SQL server you need to fool
it a bit and the code is not that efficent:

"SELECT TOP 1 [fieldname] from [yourtable] order by newid()"

Forgive me if I am wrong, but does your suggestion not
require that all the IDs be sequential. If, for instance
you started with 200 records, and deleted every other one,
you would be left with 100 even numbered records. Using
your logic, the count would be 100 and the random_number
might be odd (i.e. 33). Since there is no record ID 33
(remember all odd records were deleted), the query would
return nothing.

Hi Jamie,>select count(*) from tbl, sort of thing

randomize
count = {count varable from select (*)}
random_number= int(rnd*count)+ 1

select from tbl where id = random_number
