What is cursors?

Hi,

Cursor is a database object used by applications to manipulate data in a set on a row-by-row basis, instead of the typical SQL commands that operate on all the rows in the set at one time.

In order to work with a cursor we need to perform some steps in the following order:

1- Declare cursor

2- Open cursor

3- Fetch row from the cursor

4- Process fetched row

5- Close cursor

6- Deallocate cursor

Thanks,
