OPEN CURSOR approach- Performance

Question

Hi All,
We have a requirement wherein we are using OPEN CURSOR and FETCH CURSOR in a ABAP Program (Function Module).
Any sample code related to CURSORs will be help full.
Is OPEN CURSOR method better in terms of performance compared to simple SELECT statements?
Any help regarding this will be highly appriciated.
Thanks in advance.

Hi Shilpa,
   Yes from performance perspective if you are reading a large chunk of data then the Open Cursor gives you better performance. You mak keep you mouse cursor on the word cursor and read help.
Sample Below:
DATA: BEGIN OF count_line,
        carrid TYPE spfli-carrid,
        count  TYPE i,
      END OF count_line,
      spfli_tab TYPE TABLE OF spfli.
DATA: dbcur1 TYPE cursor,
      dbcur2 TYPE cursor.
OPEN CURSOR dbcur1 FOR
  SELECT carrid count(*) AS count
         FROM spfli
         GROUP BY carrid
         ORDER BY carrid.
OPEN CURSOR dbcur2 FOR
  SELECT *
         FROM spfli
         ORDER BY carrid.
DO.
  FETCH NEXT CURSOR dbcur1 INTO count_line.
  IF sy-subrc <> 0.
    EXIT.
  ENDIF.
  FETCH NEXT CURSOR dbcur2
    INTO TABLE spfli_tab PACKAGE SIZE count_line-count.
ENDDO.
CLOSE CURSOR: dbcur1,
              dbcur2.
