Hi Binyamin,

They match because most of the leaf rows (106536) are deleted leaf rows (106533) meaning you only have *3* non deleted leaf rows.

Basically your table has undergone a somewhat dramatic shrinkage in size.

If you want to learn a thing or two about indexes, take a took at a recent presentation of mine at
www.actoug.org.au/Downloads/oracle_index_internals.pdf

Regards

Richard
