Hi Nando,
want to be able to sort table columns alphabetically as opposed to
asciibetically. And they don't want to find all the Turkish names
starting with O-umlaut below the Z when they expect them among the
regular O's.
For case-insensitive comparisons I use UPPER(). I must admit however
that my databases don't contain millions of records; if they would,
the performance hit might be painful...
Greetings,

want to be able to sort table columns alphabetically as opposed to
asciibetically. And they don't want to find all the Turkish names
