Difference between Cluster and Non-cluster index?

Answer Posted / veerreddy

clustered index is that the order of data in table is always
equal or matches to order of data stored in index.there is
only one(1) clustered index for table.it is usually applied
on primary key column in table.

other hand the non-clustered index is that the order of data
in table is not equal or matches to order of data stored in
index.so they can be applied on non-primary key columns like
unique,foreign key etc.A table can have (249) non-clustered
indexes
