   Description
  </title>
  <para>
   <command>CLOSE</command> frees the resources associated with an open cursor.
   After the cursor is closed, no subsequent operations
   are allowed on it. A cursor should be closed when it is
   no longer needed.
  </para>
  <para>
   An implicit close is executed for every open cursor when a
   transaction is terminated by <command>COMMIT</command>
 or <command>ROLLBACK</command>.
  </para>

    an explicit <command>OPEN</command> cursor statement;
    a cursor is considered open when it is declared.
