Hi Tim,

Did you try
... where myTextColumnUsingDefaultBinaryCollation glob 'foo*'
GLOB is hardcoded as case-sensitive and more likely a candidate to
using index. Just check it.

Does Adobe actually filter out statements similar to:
select sqlite3_load_extension('mylibrary', 'entrypoint');
If they do, then they really have something against _you_ ;-)
If they don't (which is what I would wild guess) then I've offered you
something that should perform per your requirements. BTW I've a
revise, expanded version available with (portable) a NUMERIC Unicode
sort (lexicagraphic sort of variable-size text numbers sucks).

That's GLOB, already in the box and free.

If you need I can make a limited verion of my extension for you with
only the functions you need.
