Fetching data through Native SQL

[Former Member]

Hi,

What is the use of FETCH NEXT while fetching the data from the tables using Native SQL?

What is the error 923 in Native SQL?

Thanks & Regards,

hi,

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.

Hope this help, Do reward.
