Answer / vikash kumar mishra

There are five type of cursors in SQL server.
1)Base table:- This is lowest level cursor.

2)Static :- This is scrollable query cursor in earlier
versions of SQL Server Compact Edition

3)Forward-only:- The forward-only cursor is the fastest
cursor that you can update, but it does not support
scrolling.

4)Forward-only/Read-only:- Forward-only/read-only cursors,
referred to as forward-only cursors in earlier versions of
SQL Server Compact Edition, are the fastest cursors, but
cannot be updated.

5)Keyset-driven:- The keyset-driven cursor in SQL Server
Compact Edition is a scrollable cursor that you can update.
A keyset-driven cursor is controlled by a set of physical
identifiers known as the keyset.

5] Forward_only keyset : Its not scrollable, but sensitive to updation and deletion in resultset but not insertion. We can only move forward and not backward.
