How Clustered Index and Non clustered index stored on SQL
server?

Answer Posted / answerme

Clustered Index are always stored on disk in a certain
order i.e, the data on disk may well be stored in order of
the Primary Key. So the data retreival is faster, when
queried based on Primary key.

non Clustered indexes are all the other indexes on a table,
that do not dictate the order that records are stored on
disk.A non Clustered index stores all the fields that
comprise the index, plus a link to the actual full record
on disk. This link is the primary key (clustered index), so
in fact a non clustered index contains all the columns that
you specify for them plus the clustered index columns too.
