Обсуждение: Group by - Case insensitivity

Hello all!

Is it possible to setup a group by to be case insensitive and if so how?

Thank you!

Off the top of my head, I can think of a couple of ways.

select lower(name), count(*) from customer group by lower(name);

or

select min(name), count(*) from customer group by lower(name);

The second one works if you still want some semblance of the original
casing of the field.

Well, you could presumably canonicalize the field to one case or the
other, thereby forcing the issue.  That's not _exactly_ the same thing
as "case insensitivity," but it may be close enough.

Are you pondering what I'm pondering?

group by lower(field)
