diffrence between Cluster Index and non Cluster Index..

Answer / indraneelandhavarapu

The difference is that, Clustered index is unique for any
given table and we can have only one clustered index on a
table. The leaf level of a clustered index is the actual data
and the data is resorted in case of clustered index. Whereas
in case of non-clustered index the leaf level is actually a
pointer to the data in rows so we can have as many non-
clustered indexes as we can on the db.
