Eric, Oracle won't use the index in this case. Instead have a function-based index.

Does nvl have any effect on indexes. In other words would it slow down a query if you used the nvl function in the where clause on an indexed field.
i.e.
select *
from foo
where indexField > nvl(xfoo,0);
Thanks,
Eric
