Well, assuming xfoo is a variable, this is not correct...the function is not being
used on the indexed field in this case, so the index WILL be used. If xfoo is a
column in the table, then I would expect a full table scan to be used.

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
