Managing Cursors

The PL/SQL uses 2 types of cursors: implicit and explicit. The PL/SQL declares a cursor implicitly for all the SQL data manipulation statements, including the queries which return only one row. Though, for queries which return more than one row, you should declare an explicit cursor or use a cursor FOR loop.
