SQL Server Cursors Question:

A Cursor is a database object that represents a result set and is used to manipulate data row by row.
When a cursor is opened, it is positioned on a row and that row is available for processing.

Transact-SQL Server cursors use Transact-SQL statements and are declared using DECLARE CURSOR statement.
