A cursor in DB2 is primarily used to retrieve rows one at a time from the result set of an SQL query. This allows for sequential processing of the result set, enabling manipulation or analysis of each row individually. Cursors are commonly used in situations where processing each row separately is necessary, such as data validation or complex calculations.
