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,
