Answer / pervej munjal

Cursor plays there row quite nicely but although there are
some disadvantage of Cursor .
Because we know cursor doing roundtrip it will make network
line busy and also make time consuming methods. First of
all select query gernate output and after that cursor goes
one by one so roundtrip happen.Another disadvange of cursor
are ther are too costly because they require lot of
resources and temporary storage so network is quite busy.

Answer / vijay

The set of rows is returned by SELECT statementb by using
WHERE clause or not. In our application can not work
EFFICIENTLY to this result set. If we want to
access/process the entire block or row or fields or it
different kind of property, we need the mechanism. This
mechanism is called CURSOR.

SQL SERVER 2000,

Cursor is a database object used by applications to
manipulate data in a set on a row-by-row basis.

Cursor helps to update, add, select, remove on a row by row
basis on a table.

A cursor is a mechanism by which you can assign a name to
a "select statement" and manipulate the information within
that SQL statement.

We've categorized cursors into the following topics:

1.Declare a Cursor
2.OPEN Statement
3.FETCH Statement
4.CLOSE Statement
5.Cursor Attributes (%FOUND, %NOTFOUND, etc)
6.SELECT FOR UPDATE Statement
7.WHERE CURRENT OF Statement

Answer / nisha

Cursor is a programming device that allows the SELECT to
find a set of rows but return them one at a time. Cursor
should be used because the host language can deal with only
one row at a time.

Answer / sandeep

Cursor is a database object even it is treated like a data
type. It is generally used for fast and resource efficient
programming. Cursor wont fetch all datas resulted from a
select statement. Only one row at a time. this speeds up
the population of the data. In select statement all datas
shud be fetched to the client machine. Few drawbacks are
there with cursor but in some cases it works well.
