The FETCH statement in DB2 cursor operations is used to retrieve the next row from the result set of the cursor. Each time FETCH is executed, it advances the cursor to the next row in the result set, allowing the application to process the rows sequentially. FETCH returns the data from the current row and moves the cursor to the subsequent row for subsequent fetch operations.
