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.

need help with the Merge statement
I'm on: Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production
I'm currently an UPDATE statement and then it works and is accurate, it takes 30 minutes. I heard that MERGE
can do the same thing and is just as accurate and much faster!
Here's the query I want to convert into a MERGE INTO statement. I tried to do it myself, but I get errors and don't know simply, since it's new for me.
Basically I want to update table your on a corresponding condition in the table tt for 2 columns (GTP and UPDATE_DT), for UPDATE_DT I want to insert the Date current system.
Thank you!UPDATE /*+ PARALLEL (16) */ OLDER_Table ta SET (ta.GTP, ta.UPDATE_DT) = (SELECT /*+ PARALLEL (16) */ tt.GTP, SYSDATE FROM NEWER_Table tt WHERE ta.cust_id = tt.cust_id AND ta.STAMP_DATE = tt.STAMP_DATE AND ROWNUM = 1) WHERE EXISTS (SELECT 1 FROM NEWER_Table tt WHERE ta.cust_id = tt.cust_id AND ta.STAMP_DATE = tt.STAMP_DATE AND (NVL(ta.GTP, 'X') != NVL(tt.GTP, 'X')));Hello
Whenever you have a problem, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) of all of the tables involved.
Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.
If you ask on a DML statement, such as UPDATE, CREATE TABLE and INSERT statements need to re - create the tables as they are before the DML, and results will be the content of the or the tables changed when it's all over.
See the FAQ forum {message identifier: = 9360002}MERGE peut be much faster than update; Sometimes, there is no significant difference in speed.
Tables in multiple situations like this, I've never seen a case where the MERGER has been slower than the UPDATE, even if the UPDATE is sometimes easier to code and just as fast.Maybe that's what you want:
MERGE INTO older_table dst USING ( SELECT n.cust_id , n.stamp_date , n.gtp , ROW_NUMBER () OVER ( PARTITION BY n.cust_id , n.stamp_date ORDER BY n.gtp ) AS r_num FROM newer_table n JOIN older_table o ON n.cust_id = o.cust_id AND n.stamp_date = o.stamp_date AND NVL ( n.gtp , 'X' ) != NVL ( o.gtp , 'X' ) ) src ON ( src.cust_id = dst.cust_id AND src.stamp_date = dst.stamp_date AND src.r_num = 1 ) WHEN MATCHED THEN UPDATE SET dst.gtp = src.gtp , dst.update_date = SYSDATE ;As I can't test it, I can't be sure.

error with the case statement use what void const query
Hi all.
I have found the error in the result set, and then use subqueries and cases of declaration.
Preparation for example.
2 examples of tables creation.
This statement returns NULL in subqueryCREATE TABLE T1 AS ( SELECT 1 ID , 1 F1 FROM DUAL UNION SELECT 2 ID , 1 F1 FROM DUAL UNION SELECT 3 ID , 1 F1 FROM DUAL ) ; CREATE TABLE T2 AS ( SELECT 2 ID FROM DUAL UNION SELECT 3 ID FROM DUAL ) ;
But this statement (with operator CASE) does NOT return null in subquerySELECT T1.ID, TT2.ID , TT2.ISBUG AS NO_BUG FROM T1 LEFT JOIN ( SELECT ID , -1 ISBUG FROM T2 )TT2 ON T1.ID = TT2.ID WHERE TT2.ID IS NULL
Why?SELECT CASE WHEN 1 = 1 THEN 1 END AS C1, T1.ID, TT2.ID , TT2.ISBUG FROM T1 LEFT JOIN ( SELECT ID , -1 ISBUG FROM T2 )TT2 ON T1.ID = TT2.ID WHERE TT2.ID IS NULL

So, if we want to MERGE this table and update the lines with below:
merge into xx_test1 DST USING (SELECT LINE_GROUP_NUMBER, LINE_TYPE_LOOKUP_CODE, ROW_NUMBER() over(order by LINE_TYPE_LOOKUP_CODE, LINE_GROUP_NUMBER) as LINE_NUM from xx_test1 where INVOICE_ID = 131549 ) SRC ON (DST.LINE_GROUP_NUMBER = SRC.LINE_GROUP_NUMBER AND dst.LINE_TYPE_LOOKUP_CODE = src.LINE_TYPE_LOOKUP_CODE AND dst.invoice_id = 131549 ) WHEN MATCHED THEN update set DST.LINE_NUMBER = SRC.LINE_NUM ;
I get an error message:SQL error: ORA-30926: failed to get a stable set of rows in the source tables
30926 00000 - "impossible to get a stable set of rows in the source tables.
* Cause: A stable set of rows could not be achieved due to the large dml
activity or one not deterministic where clause.
* Action: Remove any non deterministic of the clauses and reissue of the dml.
I don't know why I'm getting this. Any ideas?

LINE_GROUP_NUMBER, summer time. Combination of LINE_TYPE_LOOKUP_CODE this duplication.

Return in the MERGE statement clause

I have not found ANY error while working with the UPDATE statement. Here is the code with the UPDATE statement

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
RETURNINGINTOarticle belongs to aDELETE,INSERT, orUPDATEstatement. The dynamicRETURNINGINTOarticle belongs to aEXECUTEIMMEDIATEstatement.And here is the link.
It will be useful.

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

First statement correctly the merged data, but use FULL TABLE SCANS, so it's rather slow. Second statement using a UNIQUE INDEX on the columns from_city_id, to_city_id, and query_timestamp_hh on the MAP of EXPLAIN, but during the execution of I've got ORA-00001: unique constraint (PODOWNER. 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.

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

I tried to run the update with two options:TABLE_NAME LAST_ANALYZED NUM_ROWS SAMPLE_SIZE PS_RF_INST_PROD 1/20/2010 1:14:22 AM 7194402 7194402 BL_TMP_INTRNT 1/27/2010 9:08:54 AM 885445 885445 NAP_INTERNET 1/25/2010 11:47:02 AM 7053990 560777
1. with the plan than oracle choose.
2. with notes I added.
In both cases I he collapsed after more than an hour.
Can any one suggest how to speed it up?
Below are for the two option tkprof.
Plan 1Please note that beside the defualt statistics on those tables i also gathered statistics on two column level as followed: BEGIN SYS.DBMS_STATS.GATHER_TABLE_STATS ( OwnName => 'B' ,TabName => 'BL_TMP_INTRNT' ,Estimate_Percent => 100 ,Degree => 8 ,Cascade => TRUE ,No_Invalidate => FALSE); END; / exec dbms_stats.gather_table_stats('B' , 'BL_TMP_INTRNT', cascade=>TRUE, method_opt=>'for columns SERVICE_UID size 254'); exec dbms_stats.gather_table_stats('B' , 'BL_TMP_INTRNT', cascade=>TRUE, method_opt=>'for columns FIX_IP_USER size 254');

The trick is to join only once, be updated using join views - provided that it is preserved - key or by using the merge statement.Here is an example:

vCenter 4.1/ESXi 4.1 material status "Communication error with the server.
I am slot that a brand new installation of vCenter with two new installs of ESXi 4.1 connected on it. I use on Dell PowerEdge 2950 s ESXi servers. I tired the customized version of Dell and vmware ESXi vanilla version. My host vCenter is Windows 2008 R2.
In vCenter, the two server ESXi, any version of ESXi, I run, I get "Communication error with the server" error when I click the tab hardware state. No data appears in the hardware status tab.
Only suggestion of Dell has been updated with firmware/BIOS on the server level. I did and it did not help.
Anyone has any suggestions or ideas what would cause this?
I had exactly the same problem what is to have everyone on this thread. I finally called VMware support. It is certainly a problem with Tomcat. Apparently, during my initial installation of tomcat server vCenter (on a Win2k8R2 vanilla Server / unreleased) na not create a database file. The vCenter Server uninstalled eventuall tech and went through the Setup again. For some reason any Tomcat created db it's good the second time. After installation, it takes about 5 minutes for the db should be created.
On Windows 2k8R2 it is located here: C:\Program Files\VMware\Infrastructure\tomcat\lib\xhiveConfig\data
The name of the comic is VcCache-by default-0. XhiveDatabase.DB
My server didn't have one at all. The relocation has created, at the beginning it is 0KB in size. After 5 minutes, it grows up to 25, 600KB.
Everything in my vCenter works now correctly. I'm on 4.1.320137
I hope this helps.
