In clustered and non clustered indexes which one is faster
while executing a query ?
Answer / arunyadav007
Clustered Index.
Because the leaf level of a clustered index is the actual
data and the data is resorted in case of clustered index.
In case of non-clustered index the leaf level is actually a
pointer to the data in rows. The data is stored in one
place, the index in another, with pointers to the storage
location of the data. The items in the index are stored in
the order of the index key values, but the information in
the table is stored in a different order.
Thanks,
Arun
