after a quick hop on google.. it looks like it's actually the query that needs 
to change..

"Yes. It's YOUR code that makes Oracle case insensitive. Example 1: in your 
triggers, stored procedures, and any generic SLQ statements use the UPPER and
LOWER functions whenever comparing strings. Example 2: using Oracle 8i you can 
create function based indexes like create an index on the city_name column
using the function UPPER(city_name). Then when your code queries for all cities 
where UPPER(city_name) = 'somevalue' Oracle can use the index to find the
answer."

oracle has functions to conver stuff to all caps, or all lower - upper() and 
lower() respectively..

select * from some_table where lower(some_table_field) = 
lower($some_php_variable)

this also explains why i had to cover the table and field names to uppercase in 
horde_prefs (as mentioned in one my posts this weekend on the IMP list)
