Hi

Dear Folks,

How to handle the below error, please suggest. I have migrated my database
from oracle to postgres through Ora2PG then I am getting this error for
function.

If I am writing the code for every column which are within set (column
name1, column name2, etc) then it's running successfully but if there are
so many columns with set then how can I handle this because in below code
there are 7 column with set statement and we have to write very big code
for this. Please suggest how to handle this situation.

ERROR: syntax error at or near "SELECT"
LINE 2: ...LEAD_TIME,ITEM_NUMBER,ORDER_UOM_CODE,ORDER_QTY) =(SELECT LIN...
^
********** Error **********

ERROR: syntax error at or near "SELECT"
SQL state: 42601
Character: 123

Code as below:

-------------------------------

update ppo_master_detail set (LINE_STATUS,LINE_TYPE,PROMISE_DATE,
LEAD_TIME,ITEM_NUMBER,ORDER_UOM_CODE,ORDER_QTY) =(SELECT LINE_STATUS,

LINE_TYPE,PROMISE_DATE,LEAD_TIME,ITEM_NUMBER,ORDER_UOM_CODE,ORDER_QTY
from ppo_master_detail where subscriber_id = 65 and
row_number=supplierdetail.row_number
and po_number=supplierdetail.po_number and
company_id=supplierdetail.company_id )
where po_number =PONum.po_number and company_id=PONum.company_id and
subscriber_id = 65 and row_number=supplierdetail.row_number;
--iRowCounter:=iRowCounter+1;

This Oracle's syntax is supported from 9.5.

Regards

Pavel

I don't know Ora2Pg - try to find some option to generate in old format -
or manually rewrite to supported syntax

UPDATE tab SET a = x.a, ... FROM x

I believe the following will do what you want.

WITH poupd AS
(SELECT LINE_STATUS,
LINE_TYPE,
PROMISE_DATE,
LEAD_TIME,
ITEM_NUMBER,
ORDER_UOM_CODE,
ORDER_QTY
FROM ppo_master_detail ponum,
supplierdetail sd
WHERE ponum.subscriber_id = 65
AND ponum.row_number=sd.row_number
AND ponum.po_number=sd.po_number
AND ponum.company_id=sd.company_id
)
UPDATE ppo_master_detail pmd
SET LINE_STATUS = poupd.LINE_STATUS
LINE_TYPE = poupd.LINE_TYPE
PROMISE_DATE = poupd.PROMISE_DATE
LEAD_TIME = poupd.LEAD_TIME
ITEM_NUMBER = poupd.ITEM_NUMBER
ORDER_UOM_CODE = poupd.ORDER_UOM_CODE
ORDER_QTY = poupd.ORDER_QTY
FROM pmd,
supplierdetail sdu
WHERE pmd.po_number =poupd.po_number
and pmd.company_id=poupd.company_id
and pmd.subscriber_id = 65
and pmd.row_number=sdu.row_number;

NOTE: Please avoid using uppercase and camelcase objects as PostgreSQL will
convert them to lowercase
unless you quote them.
