RE: Function based indexes

Function based indexes work fine on 8.1.6 (you must use an optimizer hint,though) as long as you have
EE version and query_rewrite_enabled is set to true for your session.

I'm sorry Helmut I do not have an answer for you.

I wanted to ask the list, has anyone successfully created a function-based index before? I tried to create one on a medium-sized table and it ran for hours and hours. (8.1.5, hp/ux), it was only UPPER(field_name). After watching that run I did not pursue it any further.

Man, Intermedia, fxn-idx's, OAS, all these mediocre-working things in Oracle are leaving a bad taste in my mouth.
