Home -> Community -> Mailing Lists -> Oracle-L -> RE: function index concepts - urgh
In no way would I ever disagree with Jared ;-), but wouldn't it be better to create two indices rather than the one?
create index HOLDER_LASTNAME_IDX on HOLDER (UPPER(LAST_NAME)); create index HOLDER_FIRSTNAME_IDX on HOLDER (UPPER(FIRST_NAME));
The select statement Jared wrote would definitely work, and you'd also have the ability to select only on first names, which having the concatenated last||first wouldn't give you.
My $0.02,

Dennis,
This should do it.
select * from holder
where last_name = upper('Taylor')
and first_name = upper('Dennis');
And no it's not Friday, it is now Saturday. ;)
