FETCH

Basic form

FETCH NEXT CURSOR c target.

Effect

Uses the cursor c to read the next line or lines from the dataset of a database table determined by OPEN CURSOR . The cursor must be a variable of the type CURSOR and must be explicitly opened with OPEN CURSOR . To specify the target area into which you read the selected data, use INTO clause target .

FETCH belongs to the Open SQL command set.

After each execution of the FETCH statement, the system field SY-DBCNT contains the number of lines read so far.

The return code value is set as follows:


SY-SUBRC = 0 At least one line was read.
SY_SUBRC = 4 No line was read.

Example

Output the passenger list for the Lufthansa flight 0400 on 28-02.1995:

TABLES SBOOK.
DATA   C TYPE CURSOR,
        WA LIKE SBOOK.
OPEN CURSOR C FOR SELECT * FROM SBOOK
  WHERE
    CARRID   = 'LH '      AND
    CONNID   = '0400'     AND
    FLDATE   = '19950228'
  ORDER BY PRIMARY KEY.

DO.
  FETCH NEXT CURSOR C INTO WA.
  IF SY-SUBRC <> 0.
    CLOSE CURSOR C. EXIT.
  ENDIF.
  WRITE: / WA-BOOKID, WA-CUSTOMID,   WA-CUSTTYPE,
           WA-SMOKER, WA-LUGGWEIGHT, WA-WUNIT,
           WA-INVOICE.
ENDDO.
