Re: select count of distinct rows

Well, I find the problem on my end. I was working with a new database
that I forgot to filler yet. Yes, it works. Jaime, I think what he is
trying to do is get the record count. I would agree that using that
statement is a bit much. But using SELECT COUNT(*) FROM mytable; would
give the same thing and should run faster.

No, it shouldn't work... actually is a non-sense, count will return
just one value so there is nothing to be distinct with...
