Merge two datasets in a DO loop

Brcmeric — Fri, 27 Aug 2010 15:44:53 +0000

I have two datasets like this:

data1 :

store sales1 sales2….sales52

1

2

3

.

.

10

data2:

Store sales1 sales2…..sales52

1

2

3

.

.

.

100

okay, now what I want is to take the first row of data1 merge it with data2, take the difference of sales between the observation from data1 and all the rows of data2;

specifically I want sales1 (of the store from data1)-sales1(all other stores in data2) then sales2- sales2…., then I want to to print this out on a different dataset,

And the MOst important part is I want to do this step for every store in data1, seperately. Like after doing it for the first row of data1 I want to do the same for the second row of data1 and so on…

So that at last if I have 10 stores in data1, I will have 10 different new datasets, showing the differences betwwen sales of each store from data1 and all the stores in data2. I would be glad if anyone can help me on this. Thanks!

Use of multiple SET/WHERE clauses in the MERGE of 2 Oracle tables

Ejpeth — Tue, 16 Dec 2008 15:49:22 +0000

Currently am able to update 1 Oracle table from another using MERGE along with WHEN MATCHED THEN UPDATE logic. Under the UPDATE command I am using a SET/WHERE to update a specific column based on certain criteria. I want to add another SET/WHERE condition to this same update which will result in an UPDATE of a diff column if a diff condition (WHERE) is met.
Below I have pasted an example of the code which is working, as well as the modified code which I am unable to run successfully. It appears 2 SET/WHERE conditions under the same UPDATE won’t work … or I have not syntactically coded this correctly. Thanks for any help you can provide:

== code below is working just fine ==
MERGE INTO mbs_daterange md
USING ( SELECT * FROM cmo_keyvals ) ck
ON (md.seqno = ck.seqno AND md.item = ck.item)
WHEN MATCHED THEN
UPDATE
SET md.end_range = ck.end_range
WHERE ck.end_range > md.end_range
WHEN NOT MATCHED THEN INSERT
(md.seqno, md.item, md.begin_range, md.end_range, md.location)
VALUES (ck.seqno, ck.item, ck.end_range, ck.end_range, NULL);
commit;

== modified code below does not work ==

MERGE INTO mbs_daterange md
USING ( SELECT * FROM cmo_keyvals ) ck
ON (md.seqno = ck.seqno AND md.item = ck.item)
WHEN MATCHED THEN
UPDATE
SET md.end_range = ck.end_range
WHERE ck.end_range > md.end_range
SET md.begin_range = ck.end_range
WHERE ck.end_range < md.begin_range
WHEN NOT MATCHED THEN INSERT
(md.seqno, md.item, md.begin_range, md.end_range, md.location)
VALUES (ck.seqno, ck.item, ck.end_range, ck.end_range, NULL);
commit;

Hello,

Can anyone, provide sample programs for SORT/MERGE statements in COBOL/400?
