In SQL Server, a cursor is a database object that enables us to retrieve and modify data from individual rows one at a time. Nothing more than a row pointer is what a cursor actually is. It always goes together with a SELECT statement. Typically, it consists of a set of SQL statements that iterate through each row one at a time in a set number of rows.

All Cursor functions are nondeterministic. To put it another way, even with the identical set of input values, these functions do not provide the same outcomes when called.
