A table can have 1 clustered index and 249 non-clustered indexes

indexes make sorting efficient

generally clustered index is ideal for the Primary Key

non-clustered indexes are ideal for columns which are used
in sorting (the columns in OrderBy)

Answer / monal

Indexes are mainly used for faster retrival of the data
from the table or view.
Primary key is best candidate for creation of clustered
key: reason all the values in Primary Key column would be
unique. Also you can create clustered index on foreign key
column of table which is used quite frequently in the join
condition and on the column which is used frequently in the
where clause of the table.

Table can have only one clusert index. When we create
primary key on a table , it will generate a Cluster index
based on this primary key and physically sort and store the
data in order of clusterd index.

Non Cluster index are used to make search more effiecient
on table for given columns on which we have speicfied non
clustered index. Non cluster index have their own separate
storage.

Answer / naren

Answer / nandkumar karlekar

Create the Clustred index when your data are divided into
some countable infinite limited sets which helps to retrive
the set of date from continus data pages from h/d.
because the clustred index stores data physically.

we can create only one clustred index for a table.

reaming searching field can be included in to the non
clust.. index
