How To Tell If A Database Table Exists?

You'd think this would be the most basic sql query in the world but noooooo!
I've tried this:

on error resume next
strsql = "SELECT * FROM " & session("TablePrefix") & CurrentTable
SET rs = conn.execute(strsql)

tableExists = 0

if (Err.number = 0) then
tableExists = 1
end if

But it doesn't return an error if the table doesn't exist. I'm searching on
the internet and hitting these long complicatred solutions involving the
database "shema". Surely there is a simple way of telling with one line of
sql if a table exists or not?
