Обсуждение: Re: [SQL] case-insensitive SORT BY?

Cheat.  Get the name back, *AND* a second "field" with the name in upper
case, and then sort by that upper-cased name.  EG:

"select name, upper(name) as key where name like '%clinton%' sort by key"

Perhaps this should go in the FAQ?  I asked it myself several months ago.

Also note that you probably want to sort by key followed by name ( ie ...
sort by key, name) so that you don't run the risk of getting something
like:

a
A
B
b

Here is a 6.4  tidbit.

    select name where name like '%clinton%' order by upper(name), name;

is allowed.  (i.e.   functions are allowed in the ORDER clause)   Like you
said, the the second attribute in the ORDER clause will be the tie breaker.
