Types of joins:

INNER JOIN
LEFT OUTER JOIN
RIGHT OUTER JOIN
FULL OUTER JOIN
CROSS JOIN

Diff in delete & truncate.

the deletion of each row gets logged in the transaction log, which makes it slow
deletes all the rows in a table, but it won’t log the deletion of each row, instead it logs the deallocation of the data pages of the table, which makes it faster


Clustered & non Clustered Indexes

In clustered index table are physically stored. Only one clustered index. The leaf nodes of a clustered index contain the data pages.
A non clustered index logical order of the index does not match the physical stored order of the rows on disk. The leaf node of a non clustered index does not consist of the data pages. Instead, the leaf nodes contain index rows

By default asp.net does not support statemanagement so we have to define it explicitly. maintaining the state(information) of the current user is called statemanagment.
diff statemanagment techniques are
1)sessions
2)query string
3)viewstate
4)caching
5)session

diff between subquery and corelated subquery?
in subquery first the the inner query will be executed then the outer query will be executed.
in corelated subquery the inner query refers to the outer query

Delegates contains reference to the methods
if a delegate contains reference to only one method then it is called as singlecast delegate
if a delegate contains reference of more than one method then it is called as multicast delegate.

we can perform statemangament in webservices using cookies.
