Is MERGE supported in Greenplum Database 4.3.5.1 build 1 - greenplum

I am trying to create a merge statement for Greenplum DB and I am getting an syntax error. So I am wondering if the MERGE is even supported the way I am writing it.
I have two approaches
Approach 1-
MERGE into public.table20 pritab
USING
(
select stgout.key1, stgout.key2, stgout.col1
from public.table20_stage stgout
where stgout.sequence_id < 1000
) as stgtab
ON (pritab.key1 = stgtab.key1
and pritab.key2 = stgtab.key2)
WHEN MATCHED THEN
UPDATE SET pritab.key1 = stgtab.key1
,pritab.key2 = stgtab.key2
,pritab.col1 = stgtab.col1
WHEN NOT MATCHED THEN
INSERT (key1, key2, col1)
values (stgtab.key1, stgtab.key2, stgtab.col1);
Approach 2:
public.table20 pritab
SET pritab.key1 = stgtab.key1
,pritab.key2 = stgtab.key2
,pritab.col1 = stgtab.col1
from
(
select stgout.key1, stgout.key2, stgout.col1
from public.table20_stage stgout
where stgout.sequence_id < 1000
) as stgtab
ON (pritab.key1 = stgtab.key1
and pritab.key2 = stgtab.key2)
returning (stgtab.key1, stgtab.key2, stgtab.col1);
Is there any other way or something is wrong with my syntax itself?


Merge is not supported in Greenplum but I wrote a blog post on how to achieve the results of a merge statement in Greenplum.

not in condition not working with Case statement PLSQL

NOT IN condition, it is not working. I have these records in the table
proj_comp_id
proj_no
1050-WE-0005
8661
TOGG0000001
1581
5207-00GAC01AA502
8662
so it should add an error for the 2nd value..but not working pls help. below code is adding errors for 1 and 3rd lines also.
SELECT p.proj_comp_no AS primarykey,
p.proj_comp_id AS proj_comp_id,
pr.proj_id AS proj_id,
p.proj_no,
CASE
WHEN p.proj_comp_id NOT IN ('5207-%',
'1051-%',
'1050-%',
'1048-%',
'1049-%',
'2006-%',
'5203-%',
'1055-%',
'1056-%',
'1054-%') and p.proj_no NOT like (1581)
THEN
'1TAG_ID does not start with project prefix, pls add project prefix(5207-, 1049-,1048)'
ELSE
'NO ERROR'
END AS tag_ID_ERROR,
p.descr AS descr
FROM proj_comp p
LEFT JOIN std_mat_cls l
ON l.std_mat_cls_no = p.std_mat_cls_no
LEFT JOIN std_mat b
ON p.proj_comp_id = b.std_mat_id
LEFT JOIN proj pr
ON p.proj_no = pr.proj_no
WHERE (SELECT m.mat_stat_ext_id
FROM mat_stat_ext m
WHERE p.mat_stat_ext_no = m.mat_stat_ext_no) IN ('N', 'P')
AND b.std_mat_id IS NULL
***

That must be because IN isn't appropriate in this context. You should switch to something else, e.g. separate LIKE conditions:
No:
WHEN p.proj_comp_id NOT IN ( '5207-%', '1051-%', '1050-%', etc.
Yes:
WHEN p.proj_comp_id NOT LIKE '5207-%'
AND p.proj_comp_id NOT LIKE '1051-%'
AND p.proj_comp_id NOT LIKE '1050-%'
etc.

The other way to test this could be solved using the InStr() function...
WHEN
InStr('5207-, 1051-. 1050-, 1048-, 1049-, 2006-, 5203-, 1055-, 1056-, 1054-', SubStr(p.proj_comp_id, 1, 5)) = 0

SQLRPGLE & JSON_OBJECT CTE Statements -101 Error

This program compiles correctly, we are on V7R3 - but when running it receives an SQLCOD of -101 and an SQLSTATE code is 54011 which states: Too many columns were specified for a table, view, or table function. This is a very small JSON that is being created so I do not think that is the issue.
The RPGLE code:
dcl-s OutFile sqltype(dbclob_file);
xfil_tofile = '/ServiceID-REFCODJ.json';
Clear OutFile;
OutFile_Name = %TrimR(XFil_ToFile);
OutFile_NL = %Len(%TrimR(OutFile_Name));
OutFile_FO = IFSFileCreate;
OutFile_FO = IFSFileOverWrite;
exec sql
With elm (erpRef) as (select json_object
('ServiceID' VALUE trim(s.ServiceID),
'ERPReferenceID' VALUE trim(i.RefCod) )
FROM PADIMH I
INNER JOIN PADGUIDS G ON G.REFCOD = I.REFCOD
INNER JOIN PADSERV S ON S.GUID = G.GUID
WHERE G.XMLTYPE = 'Service')
, arr (arrDta) as (values json_array (
select erpRef from elm format json))
, erpReferences (refs) as ( select json_object ('erpReferences' :
arrDta Format json) from arr)
, headerData (hdrData) as (select json_object(
'InstanceName' : trim(Cntry) )
from padxmlhdr
where cntry = 'US')
VALUES (
select json_object('header' : hdrData format json,
'erpReferenceData' value refs format json)
from headerData, erpReferences )
INTO :OutFile;
Any help with this would be very much appreciated, this is our first attempt at creating JSON for sending and have not experienced this issue before.
Thanks,
John

I am sorry for the delay in getting back to this issue. It has been corrected, the issue was with the "values" statement.
This is the correct code needed to make it work correctly:
Select json_object('header' : hdrData format json,
'erpReferenceData' value refs format json)
INTO :OutFile
From headerData, erpReferences )

MERGE using Rowid Oracle Conversion in Postgres

Can some help me the best way convert the below Oracle code to Postgres
MERGE INTO INCLUSION_EXCLUSION_ALL A
USING (SELECT DISTINCT IEALL.rowid rid, IE.BLACKOUT_DURATION, ie.BLACKOUT_CATEGORY
FROM INCLUSION_EXCLUSION_ALL IEALL, INCLUSION_EXCLUSION_RULES IE
WHERE IE.PRI_PROMOTION_ID = IEALL.PRI_PROMOTION_ID
AND IE.PRI_OFFER_ID = IEALL.PRI_OFFER_ID
AND IE.SEC_PROMOTION_ID = IEALL.SEC_PROMOTION_ID
AND IE.SEC_OFFER_ID = IEALL.SEC_OFFER_ID
AND IE.BLACKOUT_DURATION > 0
AND (IEALL.BLACKOUT_DURATION <> IE.BLACKOUT_DURATION OR IEALL.BLACKOUT_CATEGORY <> IE.BLACKOUT_CATEGORY)
--AND IE.INCL_EXCL_IND <> 'I'
AND IE.SECONDARY_TYPE = 'B') B
ON (A.rowid = B.rid)
WHEN MATCHED THEN UPDATE SET A.BLACKOUT_DURATION = B.BLACKOUT_DURATION, A.BLACKOUT_CATEGORY = B.BLACKOUT_CATEGORY;
Thank You,
I want to know different ways on how we can do it as the rowid's are involved in here and are not compatible with Postgres esp in Joining using Alias even by using CTID,
Please advise

1 result set from 3 queries?

I'm at my wits end attempting to make this happen. Currently I have 3 separate queries. For automation purposes I need to get the results of these three queries in one output, I cannot seem to join them properly to get the expected results.
QUERY 1:
SELECT OH.EXTN_HOST_ORDER_REF,
OL.EXTN_HOST_ORDER_LINE_REF,
OL.ORIGINAL_ORDERED_QTY,
OL.EXTN_TENDER_QUANTITY,
OL.EXTN_CUM_PICK_QTY,
OL.SHIPPED_QUANTITY,
OL.EXTN_REFUND_QTY
FROM YFS_ORDER_HEADER OH,
YFS_ORDER_LINE OL
WHERE OH.ORDER_HEADER_KEY = OL.ORDER_HEADER_KEY
AND OH.DOCUMENT_TYPE = '0001'
AND OH.EXTN_HOST_ORDER_REF = 'xxxxxxxxxxx'
ORDER BY PL.EXTN_HOST_ORDER_LINE_REF ASC;
QUERY 2:
SELECT RS.STATUS_QUANTITY AS RETURNED_QTY
FROM YFS_ORDER_HEADER OH,
YFS_ORDER_LINE OL,
YFS_ORDER_RELEASE_STATUS RS
WHERE OH.ORDER_HEADER_KEY = OL.ORDER_HEADER_KEY
AND OL.ORDER_LINE_KEY = RS.ORDER_LINE_KEY
AND RS.STATUS = '3700.02'
AND OH.EXTN_HOST_ORDER_REF = 'xxxxxxxxxxx';
QUERY 3
SELECT RS.STATUS_QUANTITY AS CANCELLED_QTY
FROM YFS_ORDER_HEADER OH,
YFS_ORDER_LINE OL,
YFS_ORDER_RELEASE_STATUS RS
WHERE OH.ORDER_HEADER_KEY = OL.ORDER_HEADER_KEY
AND OL.ORDER_LINE_KEY = RS.ORDER_LINE_KEY
AND RS.STATUS = '9000'
AND OH.EXTN_HOST_ORDER_REF = 'xxxxxxxxxxx';
The query should show NULL values where no data exists from query 2 & 3.
Thanks in advance for your help and advice!

If you are allowed to show both returned and cancelled quantities, the following simple edit should work. Hope this helps.
SELECT oh.extn_host_order_ref,
ol.extn_host_order_line_ref,
ol.original_ordered_qty,
ol.extn_tender_quantity,
ol.extn_cum_pick_qty,
ol.shipped_quantity,
ol.extn_refund_qty,
DECODE (rs.status, '3700.02', rs.status_quantity) AS returned_qty,
DECODE (rs.status, '9000', rs.status_quantity) AS cancelled_qty
FROM yfs_order_header oh
INNER JOIN yfs_order_line ol
ON oh.order_header_key = ol.order_header_key
LEFT OUTER JOIN yfs_order_release_status rs
ON ol.order_line_key = rs.order_line_key
WHERE oh.document_type = '0001' AND oh.extn_host_order_ref = 'xxxxxxxxxxx'
ORDER BY pl.extn_host_order_line_ref ASC;
