Hi,
Could you please help me in this issue.
I have a foreign key on a child table referencing the primary key of the parent table. I have created the index on the foreign key on the child table. Now, how do I know that the foreign key constraint is using the index or not. I tried to see the index name from user_constarints table, but it always shows empty. When index_name is empty, what does it mean, even though I have it. Thanks
nagu
