Well, the obvious is;
SELECT * FROM x WHERE User_Email = 'fubar' OR User_Email = 'Fubar';
But I assume you are looking for something more useful. Are you trying
to catch all entries not in all lower case? Try this:
SELECT * FROM x WHERE User_Email != lower(User_Email);
Or you can convert to lower with this:
UPDATE x SET User_Email = LOWER(User_Email);
If you have a unique index on User_Email then the ones that already
exist will fail and then you can use the first one to find the ones
that didn't get converted. Those will be the dups.
