what ever happend to a unique primary key like userID ?
>>> "gord barq" <[EMAIL PROTECTED]> 08/11/03 11:15am >>>
I have a table I'm using for logging purposes with a schema like:
create table results (
user varchar(255)
....
);
Where user is not a unique field and I want to find out how many unique
users there are in the table.
I want to do something like:
select count(count(*)) from results group by user;
But that doesn't work..
Any ideas?
Thanks
