Well, I had the problem with a similar situation where I had created an
index on the single column to improve the performance.

PM Index question
Please respond to
oracle-l@freelist
s.org
I have a query that references Table t column c in the where clause. Table
t already has an index on (column c, column d). Is there any reason to add
an index to table t that contains just column c? I know that Oracle will
use the other index because of the leading column, but is there a
performance hit due to it being a composite index?
I am running Oracle EE 9.2.0.5.
Thanks,
Rick Stephenson
