Sorry John, I don't believe you.
SELECT * FROM XXXXXXXX
WHERE OWNERNAME = 'RANKLEY'
ORDER BY OWNERNAME
cannot possibly take minutes to return a handful of records if
OWNERNAME is indexed. Well, maybe it is possible, but then there are
other problems that causes this (e.g. Windows XP doing a file copy of
.gdb files before allowing anyone to access them or there being
thousands of fields to transfer and you connecting through the
Internet), not the select itself.
Firebird is generally fast, and - if treated correctly - a lot better
than Paradox to handle large tables. I would expect the above query to
execute in less than a second, not two seconds.
So, what is it that you're not telling us? Is the above SQL the exact
query you're executing or are there other parts you've not told us
about. What's the reported plan (you can find this by e.g. typing it
into IB_SQL and prepare the statement) and your table/index definitions?
HTH,
