Dear Richard,<br>
<br>
Sorry for that :) and thanks for your tips, but it didn't solve my
problem. Maybe because my postgresql knowledge limitation. I have tried
your suggestion, my view like this :<br>
<br>
-- View: "vwlapjual"<br>
<br>
-- DROP VIEW vwlapjual;<br>
<br>
CREATE OR REPLACE VIEW vwlapjual AS <br>
SELECT tblpenjualan.tanggal, tblpenjualan."operator",
tblpenjualan.noinvoice, tblpenjualan.bayar, tblpenjualan.bayarvocher,
tblpenjualan.jam, tblpenjualan.id, tblpenjualan.jeniscard,
tbltransaksi.kodeproduk, tbltransaksi.keluar, tbltransaksi.harga,
tbltransaksi.disc1, tblproduk.namabarang, tblproduk.subkat,
tblsubkategori.subkategori, tblkategoriproduk.kode,
tblkategoriproduk.kategori, tbltransaksi.hargapokok *
tbltransaksi.keluar::numeric(2,0) AS modal, <font color="#ff0000"><b>tbltransaksi.keluar
* tbltransaksi.harga - (tbltransaksi.disc1 / 100::numeric(3,0) *
(tbltransaksi.keluar * tbltransaksi.harga))::numeric(10,0) AS jumlah</b></font>,
<font color="#ff0000"><b>tbltransaksi.keluar * tbltransaksi.harga -
tbltransaksi.disc1 / 100::numeric(3,0) * (tbltransaksi.keluar *
tbltransaksi.harga) - (tbltransaksi.hargapokok *
tbltransaksi.keluar)::numeric(10,0) AS profit</b></font><br>
FROM tblpenjualan<br>
JOIN tbltransaksi ON tblpenjualan.id = tbltransaksi.jualid<br>
LEFT JOIN tblproduk ON tbltransaksi.kodeproduk::text =
tblproduk.kode::text<br>
LEFT JOIN tblsubkategori ON tblproduk.subkat::text =
tblsubkategori.id::text<br>
LEFT JOIN tblkategoriproduk ON tblsubkategori.kategoriid::text =
tblkategoriproduk.kode::text;<br>
<br>
ALTER TABLE vwlapjual OWNER TO hpl;<br>
<br>
and the view result like this :<br>
<br>
"2008-07-20";"ULY";"01-200708";"Tunai";0.00;"1899-12-30
21:14:47+06:55:25";1;"";"8993417200021";1.00;4200.00;0.00;"ELIPS HAIR
VITAMIN ";"121";"VITAMIN RAMBUT";"NF";"Non Food";3960.00;<font
color="#ff0000"><b>4200.0000</b></font>;<font color="#ff0000"><b>240.000000000000000000000000</b></font><br>
<br>
Thanks for any suggestion.<br>
<br>
Regards,<br>

Because you've cast 100 to numeric, rather than numeric(10,2) or
whatever. This means you get the full accuracy on the calculation - it
won't ever trim a numeric (that's the whole reason to have the type).
