      SET @cursor_variable =  CURSOR [ FORWARD_ONLY | SCROLL ] 
         [STATIC | KEYSET | DYNAMIC | FAST_FORWARD ] 
            [READ_ONLY | SCROLL_LOCKS | OPTIMISTIC ]  [TYPE_WARNING ] 
               FOR select_statement

   FAST_FORWARD A FORWARD_ONLY, READ_ONLY cursor with optimizations enabled.
   FORWARD_ONLY Only allow FETCH NEXT.

   KEYSET       Fix the membership and order of rows in the cursor.
   DYNAMIC      Reflect all data changes made to the rows.
