Bill,

When you run the query, how fast is the response?


Just to add a bit to Tom's response:

Why not do a 10046 trace on the query?

Run it both with and without the index hint and
compare the results.

An excellent method for comparing the 2 would
be to use runstats -  http://asktom.oracle.com/tkyte/runstats.html
