also, just to clarify - i didn't want a case insensitive compare but a
specific sql generated
just to give a quick illustration
With this table structure:
CREATE TABLE names (
id serial not null primary key ,
name varchar(255) not null
);
CREATE UNIQUE INDEX names_name_uidx ON names(lower(name));
Postgres and Oracle will optimize this search against the index:
"""SELECT * FROM names WHERE lower(name) = '%s'""" %
search.lower()
Doing an ilike or similar won't work -- while the effect is a "case
insensitive search", the search is actually case sensitive.
The nice things about function based indexes like this, is that you
can both preserve uniqueness on a string ( usernames, email addresses,
etc ) and also gain a little speed on your most often used lookups.
