ORA-00971: Missing SET keyword - sql

Question

I'm getting a confusing "ORA97100 missing SET keyword" error when trying to run this simple UPDATE statement.
UPDATE
(SELECT
RKAP_PROYEKSI.ID AS ID,
RKAP_PROYEKSI.TAHUN AS TAHUN,
RKAP_PROYEKSI.KODE_ANGGARAN AS KODE_ANGGARAN,
RKAP_PROYEKSI.JENIS_BIAYA AS JENIS_BIAYA,
RKAP_PROYEKSI.SUBTOTAL AS SUBTOTAL,
RKAP_PROYEKSI.TOTAL AS TOTAL,
RKAP_PROYEKSI.BELONGS_TO AS BELONGS_TO,
RKAP_PROYEKSI.NOMOR AS NOMOR,
RKAP_PROYEKSI.STATUS AS STATUS
FROM WOS.RKAP_PROYEKSI
LEFT JOIN WOS.RKAP_MASTER_KODE ON RKAP_MASTER_KODE.ID_KODE = RKAP_PROYEKSI.KODE_ANGGARAN
LEFT JOIN WOS.RKAP_USER ON RKAP_USER.BIRO = RKAP_MASTER_KODE.BIRO
WHERE TAHUN = '2018' AND RKAP_MASTER_KODE.BIRO = 'BSI') AS helper
SET helper.STATUS = 0
I've also tried to erase the "AS", but still get in error.
Any well thought to advise will be appreciated.
Thanks

Answer 1

You can use WITH..AS clause :
UPDATE RKAP_PROYEKSI R
SET STATUS = (
WITH RP AS
(
SELECT
RKAP_PROYEKSI.ID AS ID,
RKAP_PROYEKSI.TAHUN AS TAHUN,
RKAP_PROYEKSI.KODE_ANGGARAN AS KODE_ANGGARAN,
RKAP_PROYEKSI.JENIS_BIAYA AS JENIS_BIAYA,
RKAP_PROYEKSI.SUBTOTAL AS SUBTOTAL,
RKAP_PROYEKSI.TOTAL AS TOTAL,
RKAP_PROYEKSI.BELONGS_TO AS BELONGS_TO,
RKAP_PROYEKSI.NOMOR AS NOMOR,
RKAP_PROYEKSI.STATUS AS STATUS,
0 AS ZERO_STATUS
FROM WOS.RKAP_PROYEKSI
LEFT JOIN WOS.RKAP_MASTER_KODE ON RKAP_MASTER_KODE.ID_KODE = RKAP_PROYEKSI.KODE_ANGGARAN
LEFT JOIN WOS.RKAP_USER ON RKAP_USER.BIRO = RKAP_MASTER_KODE.BIRO
WHERE TAHUN = '2018' AND RKAP_MASTER_KODE.BIRO = 'BSI')
SELECT RP.ZERO_STATUS
FROM RP
WHERE RP.ID = R.ID
)

Answer 2

I think you can phrase this as:
UPDATE WOS.RKAP_PROYEKSI p
SET STATUS = 0
WHERE p.TAHUN = '2018' AND
EXISTS (SELECT 1
FROM WOS.RKAP_MASTER_KODE mk JOIN
WOS.RKAP_USER u
ON u.BIRO = mk.BIRO
WHERE mk.ID_KODE = p.KODE_ANGGARAN AND
mk.BIRO = 'BSI'
);
I don't see what RKAP_USER is being used for, but I left it in the query, just in case.
