What is clustered and non-clustered indexes?
Answer Posted / shubhi
There are clustered and nonclustered indexes. A clustered
index is a special type of index that reorders the way
records in the table are physically stored. Therefore table
can have only one clustered index. The leaf nodes of a
clustered index contain the data pages.
A nonclustered index is a special type of index in which
the logical order of the index does not match the physical
stored order of the rows on disk. The leaf node of a
nonclustered index does not consist of the data pages.
Instead, the leaf nodes contain index rows.
