Misalkan di User SCOTT, mempunyai tabel TFORM01, TFORM02, TFORM03, TFORM04 yang isi field2-nya ada 1 yang sama yaitu field NEG tentunya dengan tipe data yang sama.

Anda menginginkan update NEG yang kosong menjadi ‘INDONESIA’ ke semua tabel di user SCOTT

Cara-nya adalah seperti ini

DECLARE

CURSOR c1 IS

— ambil table apa saja yang ada di user scott

select TABLE_NAME from all_tables

where owner=‘SCOTT’;

c1rec c1%ROWTYPE;

kalimat varchar2(500);

BEGIN

OPEN c1;

LOOP

FETCH c1 INTO c1rec;

EXIT WHEN c1%NOTFOUND;

— script update dan jalankan

kalimat:= ‘begin UPDATE ‘||c1rec.TABLE_NAME||‘ SET NEG=”INDONESIA” WHERE NEG is null; end;’;

begin

execute immediate(kalimat);

commit;

exception when others then

— kondisi jika pada tabel, field tsb tidak diketemukan

dbms_output.put_line(‘Table ‘||c1rec.TABLE_NAME||‘ tidak ada field NEG, ‘||sqlerrm);

end;

END LOOP;

CLOSE c1;

END;
