Kepada Teman-teman semuanya,
Dalam melakukan tuning SQL ada yang saya ingin tanyakan mana yang lebih
cepat antara SQL1 dan SQL2? dan alasannya kenapa ya?
SQL1 = select a.no,b.kdbarang
from faktur a,faktur_d b
where a.no=b.no
and a.tglfaktur between '01-JAN-2006' and '31-JAN-2006'
and a.kdpel between '001' and '010'
SQL2 = select a.no,b.kdbarang
from faktur a,faktur_d b
where tglfaktur between '01-JAN-2006' and '31-JAN-2006'
and a.kdpel between '001' and '010'
and a.no=b.no
NB : Untuk semua field yang difilter telah diberi index.
Mungkin teman-teman ada yang mengetahuinya.
Thanks,
Agus.
