Using the merge statement on support-compatible version table time invalid
Hellojust a simple question: is it possible to use a merge statement on a table of valid time support-compatible version?
For the next test, I get an ORA-01733.
(t1 is the version table compatible with time valid support t1 and t2 have the same structure: two fields: NAME and CODE (pk))
merge into < table1 > t1
with the help of < table2 > t2
on (t1. CODE = t2. CODE)
when matched, THEN update set t1.NAME = t1.NAME
where <>t1.NAME, t2.NAME;
Thank you
Hello
The sql merge operation does not currently work with versioned tables, with or without validtime. The optimizer of the merger results in insert/update statements on the underlying table for the _LT. As a result, instead of triggers that are created during the enableversioning are never triggered.
Kind regards

Different result by using the MERGE statement
I have 2 SQL statements:

First statement correctly the merged data, but use FULL TABLE SCANS, so it's rather slow.

IDX_CQS_AGGR_3COL) violated. What is the problem with the second statement - especially with this line:
WE (pca.from_city_id = pcah.from_city_id AND pca.to_city_id = pcah.to_city_id AND pca.query_timestamp_hh = pcah.query_timestamp_hh) Can I use a more complex condition in the MERGE statement? Because it seems that not all the conditions have been taken...
???
Select pcah.from_city_id, pcah.to_city_id, PT_CQS_AGGR_TEMP Lady pcah.query_timestamp_hh
less
Select pca.from_city_id, pca.to_city_id, pca.query_timestamp_hh PT_CQS_AGGR pca
somewhere the conditions limiting the time.
(or whatever the columns make up the stress of failing)
In addition, select for each column in the constraint of failure where the column is null. If one of these columns is null, equality fails, even if both are null, because null <> null. So you will get a "no match" if all values are the same and it is set to null.
Edit: Oh, slap forehead, that is why one works and the complete analysis. As SomeoneElse said, it normalizes the type of data and concatenates, comparison null to no effect and refusing all usual index.

Error in the Merge statement using dblink
Hello
I am facing the following error when you use the merge statement using the dblink.
ORA-02069: global_names must be set to true for this operation parameter.
I can use the same dblink in my select insert and update statements but when I try to use merge then he invites the error said, is also not any syntax error as same statement can be used on the same tables of database instead of dblink.
Please suggest any help will be much appreciated.
Thanks in advance
Hi Aqeel
If insert and update statements work well through links db, then it should not be a problem with the merge statement. But if you are faced with the question, so please check the entire sql statement with tnsnames on both sides. Please share the tnsnames for the two dbs with dblink ddl.

When using the merge and when to use updated
Hi friends,
Given the best performance... purpose of this discussion is when we should use statement UPDATE and when we should use MERGE statement in oracle update of thousands of records.
Kindly Guide.
Kind regards
Himanshu
Hello
Looking for a couple to a few rules that you can use to decide whether to use the MERGE or UPDATE, without actually testing two meanings?
If so, use MERGE when
(1) (sometimes) need to add new lines
(2) it is simpler. This includes special cases
(2A) an UPDATE statement uses a subquery in the SET clause and then (mostly) repeats the same subquery in the WHERE clause
(2B) you want to use the analytical functions or CONNECT BY in a subquery
These rules are NOT guaranteed to work in all situations.
Kimmy says:
Hello
... My requirement is only UPDATED records about 200 to 500K (NOT followed by update of insertion).
So the rule (1) above does not apply in this case.
What I observed in the update using a MERGE statement and UPDATE is:
Update with the MERGER was faster however explain the bytes consumed to the query plan MERGE has been compared more update.
Use the tool that works best for your needs. If users are complaining that something shows more bytes used in a plan to explain, so maybe it's a reason for the UPDATE.
Where I work, where is the fastest is usually more important.
In addition, I want to get clearity
1. "if I should use MERGE if I need to update recrods using the unique table" as shown below: OR update will be good to use in this case:
MERGE INTO MKT_DATA inmkt
C using (SELECT Customer_Code, region, State OF CUSTOMER_DATA)
ON (inmkt. Distributor_Code = c.Customer_Code AND inmkt. DISTRIBUTOR_CODE IS NOT NULL)
WHEN MATCHED THEN
Updated the inmkt VALUE. Distributor_Region = c.Region,
inmkt. C.State = Distributor_Province;
UPDATE MKT_DATA inmkt
SET (inmkt. Distributor_Region, inmkt. Distributor_Province) =
(SELECT c.Region, c.State OF CUSTOMER_DATA c
WHERE c.Customer_Code = inmkt. Distributor_Code)
WHERE inmkt. DISTRIBUTOR_CODE IS NOT NULL;
2 statements above are not equivalent.
The UPDATE statement changes all the lines in the table mkt_data that have a distributor_code, this distributor_code be in the table customer_data or not.
You want something that is equivalent to the MERGE statement, you can use:
UPDATE MKT_DATA inmkt
SET (inmkt. Distributor_Region, inmkt. Distributor_Province) =
(SELECT c.Region, c.State
OF CUSTOMER_DATA c
WHERE c.Customer_Code = inmkt. Distributor_Code
)
WHERE THERE ARE
(SELECT 1
CUSTOMER_DATA C2
WHERE the c2. Customer_Code = inmkt. Distributor_Code
)
;
It basically uses the same auxiliary request 2 times (article 2 (a), so I would use MERGE if these are the results I wanted.
If you have a foreign key constraint, which ensures that each distributor_code in mkt_data will match a line in customer_data, then the 2 statements above will produce the same results. In this case, I find the UPDATE statement simpler and probably use it rather than MERGE.
2. to Updating huge amount of records MERGER must be used instead of update?
I don't know of all short reign as the "use X whenever you have more than 100,000 lines".
3. If in the update, I need to use several tables then I have to use MERGE?
MERGE IN MKT_DATA2 t
WITH THE HELP OF)
SELECT DISTINCT srt. Sales_Id, tmkt. Cust_Code, srt. PRODUCT_CENTER
OF srt, CUSTOMER_DATA c, MKT_DATA2 tmkt SALESTERR_PL
WHERE tmkt.state_Id = 10423
AND tmkt. Business = 'MARKETING'
AND c.CUST_CODE = tmkt. Cust_Code
AND c.Rollup_Code = srt. CUST_CODE
AND srt. PRODUCT_CENTER = tmkt.PL
) d
WE (t.state_Id = 10423
AND t.BA = 'MARKETING'
AND t.Cust_Code = d.Cust_Code
AND t.PL = d.PRODUCT_CENTER
AND t.Cust_Code IS NOT NULL
)
WHEN MATCHED THEN
UPDATE SET t.Sales_Id = d.Sales_Id;
UPDATE MKT_DATA2 tmkt
SET Sales_Id = (SELECT SALES_ID OF SALESTERR_PL srt
WHERE the srt. CUST_CODE = (SELECT ROLLUP_CODE FROM CUSTOMER_DATA c
WHERE c.CUSTOMER_CODE = tmkt. Cust_Code)
AND srt. PRODUCT_CENTER = tmkt.PL)
WHERE business = 'MARKETING'
AND state_Id = 10423;
Once again, those who are not equivalent. The UPDATE statement can change more lines than the MERGE statement.
In addition, you can use the MERGE statement:
MERGE IN MKT_DATA2 t
WITH THE HELP OF)
SELECT DISTINCT srt. Sales_Id, tmkt. Cust_Code, srt. PRODUCT_CENTER
OF srt, CUSTOMER_DATA c, MKT_DATA2 tmkt SALESTERR_PL
WHERE tmkt.state_Id = 10423
AND tmkt. Business = 'MARKETING'
AND c.CUST_CODE = tmkt. Cust_Code
AND c.Rollup_Code = srt. CUST_CODE
AND srt. PRODUCT_CENTER = tmkt.PL
) d
WE (t.Cust_Code = d.Cust_Code
AND t.PL = d.PRODUCT_CENTER
)
WHEN MATCHED THEN
UPDATE SET t.Sales_Id = d.Sales_Id
WHERE t.state_Id = 10423
AND t.BA = 'MARKETING'
- AND t.Cust_Code IS NOT NULL - does not need, said subquery 'c.CUST_CODE = tmkt. Cust_Code ".
;
If you would care to publish the sample data, I was able to test this.
4. when the UPDATE is preferred over the MERGER?
In simple cases, including situations where all you need to know are on the line itself, such as:
UPDATE emp
SET sal = sal * 1.05
Job WHERE NOT IN ('MANAGER', 'PRÉSIDENT')

Return in the MERGE statement clause

I use Oracle 10 g Version
I tried the code using UPDATE with return Clause & MERGER with return below Clause.
I have not found ANY error while working with the UPDATE statement. Here is the code with the UPDATE statement
DECLARE TYPE empno_list IS TABLE OF emp.empno%TYPE; vempno_list empno_list; BEGIN UPDATE emp SET comm = 11 WHERE deptno IN (SELECT deptno FROM dept) RETURNING empno BULK COLLECT INTO vempno_list; FOR i IN vempno_list.FIRST .. vempno_list.LAST LOOP DBMS_OUTPUT.put_line ('Values of EMP ' || vempno_list (i)); END LOOP; END;

Probably because BACK IN clause does not belong to the MERGE statement. It is available only for INSERT, UPDATE, and DELETE. Here's the quote from Oracle Documentation:
The static method
RETURNING
INTO
article belongs to aDELETE
,INSERT
, orUPDATE
statement. The dynamicRETURNING
INTO
article belongs to aEXECUTE
IMMEDIATE
statement.And here is the link.
It will be useful.

Problem in the Merge statement
Hi all
I use the merge updated statement 30000 records of tables having 55 records of Lakes.
But it takes a lot of time as I kill the session after 12 hours, as it was still ongoing.
So, the same day I m using cursors, it will end in less than 3 hours.
I used merge is: -.
MERGE IN Table1 a
USING (SELECT MAX (TO_DATE (TO_CHAR (contact_date, "dd/mm/yyyy")
|| contact_time,
"jj/mm/aaaa HH24:Mi:SS".
)
) m_condate,.
appl_id
FROM Table2 b,.
(SELECT DISTINCT acc_no acc_no
IN table 3, Table1
WHERE acc_no = appl_id AND delinquent_flag = 'Y '.
AND financier_id = 'NEWACLOS') d
WHERE d.acc_no = b.appl_id
AND (contacted_by IS NOT NULL
OR followup_branch_code IS NOT NULL
)
GROUP BY appl_id) c
WE (a.appl_id = c.appl_id AND a.delinquent_flag = 'Y')
WHEN MATCHED THEN
UPDATE
SET last_contact_date = c.m_condate;
In this query, table 1 has 30000 documents and table 2 and table 3 have records 3670955 and 555674 respectively.
Please suggest, what I'm doing wrong with merger, because according to my understanding merge statement is much better than the updates or updates using cursors.

Question about the MERGE statement
Hi all
I have a small question... I can post code, table creation, etc... but I think this question can be able to be simply answered, if I explain it. If you want me to zip codes, etc... then just ask and I'll do it.
Here it goes:
I have a set up merge statement, and I have two columns. One is named ADD_DT, and the other is called LST_UPD_DT.
Update in the merge statement, the LST_UPD_DT column is updated with the SYSDATE.
When it is inserted in the merge statement, the ADD_DT column is updated with the SYSDATE.
So, here is my question:
Regardless of whether or not the information is updated, the LST_UPD_DT updates the SYSDATE every time. Any advice on how to update the LST_UPD_DT column only if information is changed/updated, so that the information is not changed would be not updated by the SYSDATE? I hope that this question was not too complicated.
Thank you all and if you want to see the code or examples of table... Please ask and I'll post one. I just thought that this may be able to meet without it.Hello

Here's one way:
MERGE INTO tbl_suppliers sm USING ( SELECT d.* FROM d_suppliers d LEFT OUTER JOIN tbl_suppliers t ON t.supp_cd = d.supp_cd WHERE t.supp_cd IS NULL OR DECODE (t.supp_nm, d.supp_nm, 0, 1) = 1 ) ds ON (sm.supp_cd = ds.supp_cd) WHEN MATCHED THEN UPDATE SET sm.supp_nm = ds.supp_nm, sm.lst_upd_dt = SYSDATE WHEN NOT MATCHED THEN INSERT (sm.supp_cd, sm.supp_nm, sm.add_dt) VALUES (ds.supp_cd, ds.supp_nm, SYSDATE); SELECT * FROM tbl_suppliers ORDER BY SUPP_CD;
This can be more efficient, because it does not generate redo, or triggers, when two tables have exactly the same line.

I use the current trial of Acrobat DC version. I opened a PDF I created in Corel Draw by publication in PDF format. I tried to copy and paste text from it to a Word 2007 document. The copy option was available, but when I went to the document and chose paste, it was nothing. I then tried the same thing but sticking in a document of Corel. The same problem. It seems that the text has been copied, but I'm unable to paste it into another program. Is this real?
Is it permanently available text? (Can highlight you)?
This seems a strange way of working well - why not copied from the draw to Word?

Hairlines between Forms after using the merge tool (Pathfinder)
Hi all
I've got this camouflage complicated as the design of all kinds of forms, but only using 5 colors.
None of my items have traits.
I have selected and used the merge tool in the pathfinder (because I have to provide the document without forms overlapping).
When you look close to the result, you notice that there are some white hairlines around all forms.
This is really a deficiency, because if I slide a red rectangle behind the work, she appears in the hairlines.
I have read the other subjects 'loose' Illustrator here, but could not find a solution to my problem.
Thank you all in advance!
qrisqris,
It may be an artifact of the (reverse) screen.
What happens if you uncheck Edit > preferences > General > work of Anti-Aliasing?
And what happens if you save it as a PDF or print or save to the Web, or export to a raster format?
You would camouflage true if you could do the background shine through everything.

I had a problem. I can't pass as parameter to the function by using the select statement. But it can pass as a parameter using the "code". How can I solve this problem?
For example,.
Select * from table (SplitFunction ('HS750020, HS750021')) < < < this work.
but
Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36')) < < < do not work.
Thank you for trying to help him. Thank you.Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36'))< do="" not="">
Try like this
select * from table(select splitfunction(lot_no) from tracer_search_schedule where job_id='36')
Just make sure that your subquery returns only 1 row.

insert/update County in the merge statement
