Re: problem with distinct not distincting...

I see you have the length included.

Perhaps, UTF8 characters in one and ascii in the other?

Are you sure that one of those entries doesn't have a trailing space?

Subject: [GENERAL] problem with distinct not distincting...

I have a pretty basic query;

select distinct on (name) name, length(name) from drugs where customer_id IS NOT NULL order by name;

which I'd expect to only return me a single drug name if there are duplicates, yet I get

name | length
==========
Roaccutane | 10
Roaccutane | 10

table encoding is UTF8...

I'm scratching my head!

Thanks,

John.
