Replication :: Metadata Deletion Error

Apr 12, 2011

I setup merge replication about 3 weeks ago between a few databases all running SQL 2008 SP1:

DB1 - This database is the publisher and distributor. DB2 - This database is a write-only subscriber (-EXCHANGETYPE 1) to DB1.
DB3 - This database is a write-only subscriber (-EXCHANGETYPE 1) to DB1.
DB4 - This database is a write-only subscriber (-EXCHANGETYPE 1) to DB1.
DB5 - This database is a read-only subscriber (-EXCHANGETYPE 2) to DB1.
DB6 - This database is a read-only subscriber (-EXCHANGETYPE 2) to DB1.

Everything was running fine, then suddenly one at a time the replication jobs for DB2, DB3, and DB4 all started reporting the error:

The Merge Agent failed after detecting that retention-based metadata cleanup has deleted metadata at the Publisher for changes not yet sent to the Subscriber. You must reinitialize the subscription (without upload). (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199402)

I was able to manually upload data from DB2, DB3, and DB4 to DB1 then reinitialize the subscriptions.  However, I don't understand why only those three subscriptions failed.  I have other merge replication jobs between the same SQL instances that are still running fine.  The only unique thing I can determine about the failed subscriptions is that they are write-only.  I really don't want to make them read/write, as it would cause a lot of unnecessary network traffic to flow between them.

Based on what I've been able to gather, the subscriptions were marked as expired which caused this problem.  If I change subscriptions to never expire to get around this problem, is that going to cause my distribution DB to grow unchecked?  Are there other ways to solve this problem?

I have a dts which creates a table which is utilized on my localintranet. The DTS runs without error and the table iscreated/populated/transfered to the appropriate db. Then it appearsthat there is an action on this table which truncates it. I have beenunable to determine the culprit. Can I create a trigger that willcapture truncation? I have tried to create a trigger to capture thisinformation but none that I attempt seem to work on capturing atruncation or a drop table and re-create.Any help would be greatly appreciated.MT.

Data Deletion On MS Access Table Hangs

Jan 18, 2008

Hello,
I have not been able to locate information on the following problem. The first step I have in a packge (Execute SQL Command) is to delete the data from an MS Access database table. The package hangs at this step after all validation is complete. In the package, once the table data is deleted, it is repopulated in a later step. The deletion step and the repopulation step use the same connection manager.

There is no information in the log about an error. At the time the package ran, there was a lock file on the database with about six users connected. I'm not sure what version of Access the database was created in, but I have 2003 on my machine, and I cannot open the database.

Any ideas?

Thank you for your help!

Replication Without Deletion

Mar 19, 2007

Hello there,

We are currently setting up out production server to the following requirements:

1. Every month, delete records that haven't been changed in the last 90 days.
2. Replicate insert statements to a backup database which will keep track of all data, and act as an archive/data warehouse.

The first step is easy, as it is just a script that checks the date of the last change on each row. However, the second step is a bit more tricky. We tried setting up replication between two test databases, but we ran into the following problem: Whenever old data has been deleted in the production database, the replication agent deletes it in the data warehouse database too.

Is it possible to override or disable this, so data is only inserted/updated, and not deleted? No applications using the database deletes records, so database integrity should not be a problem.


Thanks for your time,

Ulrik Rasmussen

Database Deletion

Apr 15, 2008

While performing import actions I had a system freeze, when the system returned the sessions had been closed and the database had vanished, with the help of support we recovered the database only to find that the original project ID had a suffix attached ( Original 40/0110, New 40/0110-1 ), when I try to return it to it's original numbering convention it says it has to be a unique number which suggests to me it is not deleted but hiding in the background, can the original be recovered or is it possible to renumber the recovered database, I have searched the whole of the databases and the original is nowhere to be seen.

Deletion In Trigger

Oct 12, 2013

table1 has a PK_tbl1 which matches FK_tbl1 in table2 and the relationship is one to one. Like this:

table1 has columns of UnitId, Code ...
table2 has columns of ItemID, UnitId ...

So if I need remove an item from table1 I must remove the matched one in table2 first.

delete from table2 where UnitId = xxx
delete from table1 where UnitId = xxx

Now I need create a trigger on table1 for deletion:

CREATE Trigger [dbo].[Table1_Delete]
ON [dbo].[Table1]
FOR DELETE

Deletion Query

May 29, 2008

Ok, so I have an issue, was wondering if anybody else has any suggestions.

I have a table that is pretty large, in all regards. It is a "message" table that holds text messages that users send to each other.

1. Has some data fields, integers, dates, some bit columns, a message subject field (varchar(250)), and a message body field (field type = text)
2. Table contains about 70 million records
3. Table has 6 indexes associated to it
4. Table has 2 views associated to it.
5. Table has 8 foreign keys associated to it.

I need to delete, oh, about 90,000 records out of this 70 million record table. I am able to disable the foreign keys to this table for deletion, but that does not seem to mitigate the problem. I think the issue lies with having to update the indexes as well as the views.

When I execute the select statement to retrieve the records I need to delete, it executes pretty quickly, no problems there that I can see.

The issue comes when I try to delete the records, it takes way too long, and we know it. We let it run for an hour and it didn't really get anywhere. This is in a server environment, some pretty decent hardware, 8gig memory, fast SCSI drives, 8 core processors, i don't know the exact specifics, but they're not bad.

Here's a DBCC SHOWCONTIG on our table

DBCC SHOWCONTIG scanning 'message' table...
Table: 'message' (1448040590); index ID: 1, database ID: 13
TABLE level scan performed.
- Pages Scanned................................: 51602
- Extents Scanned..............................: 6486
- Extent Switches..............................: 6948
- Avg. Pages per Extent........................: 8.0
- Scan Density [Best Count:Actual Count].......: 92.83% [6451:6949]
- Logical Scan Fragmentation ..................: 0.54%
- Extent Scan Fragmentation ...................: 0.93%
- Avg. Bytes Free per Page.....................: 93.5
- Avg. Page Density (full).....................: 98.85%
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

This is from our dev environment which is but a portion of our production db- but I presume our production environment will have similar percentages (not necessarily the pages scanned)

Any suggestions on how to delete records efficiently?

The Push Method Returned One Or More Error Rows. See The Specified Error Table. [ Error Table Name = ]

Jan 10, 2008

Hi,
I have application in which i am performing synchronization between SQL Server 2000 and SQL Server 2005 CE.
I have one table "ItemMaster" in my database.There is no relationship with this table,it is standalone.I am updating its values from Windows Mobile Device.

I am performing below operations for that.
Step : 1 Pull To Mobile



Code BlockmoSqlCeRemoteDataAccess.Pull("ItemMaster", "SELECT * FROM ItemMaster", lsConnectString,RdaTrackOption.TrackingOn);





Step : 2 Using one device form i am updating table "ItemMaster" table's values.

Step : 3 Push From Mobile



Code BlockmoSqlCeRemoteDataAccess.Push("ItemMaster", msConnectString);




So i am getting an error on 3rd step.
While i am trying to push it says,
"The Push method returned one or more error rows. See the specified error table. [ Error table name = ]".
I have tried it in different ways but still i am getting this error.

Note : Synchronization is working fine.There is not issue with my IIS,SQL CE & SQL Server 2k.

Can any one help me?I am trying for that since last 3 days.

Deletion And Identity Reset

Oct 13, 2005

Obviously to delete all records from DB table is simple, however, I would like to make my whole Live DB pretty much empty.  I've copied all my data from my test DB over to my live DB (didn't mean to but I did).  I would like to remove all the data and the identity values, resetting them back at their original values.  Is there a simple way or do I have to do it the hard way.  That being going in and removing Identity, saving and then placing identity back on the DB Table.

Daily Deletion Of Records

May 12, 2004

Ladys, Gentlement, I have table that grows anywhere from 200,000 to 1,000,000 records perday. Besides that I need to keep at least 6 months historical data from this same table. The transaction log was purged after each batch when testing data monthly. I'm looking for some way of deleting just one day's data if it meets a criteria. It must remain within the 6 months period of historical data. This is what I've come up with so far"

select * FROM dbo.Temp_table WHERE datediff(day, DATE_TIME, getdate()) >= 180

If it meets this criteria I can change the select to a delete? Please Let me know what you think

Alert On Data Deletion

Jul 23, 2005

We have an employee table that contains bank details and are experiencingproblems with account numbers being erased and lost. In order to track downwhy this is happening (either due to our application code or SQLreplication) we'd like to be able to prevent certain columns from beingdeleted if they already contain some data.Is it possible to setup a check constraint to prevent our ee_acct_no columnsfrom being set to NULL or blank strings if it contains an account number(i.e a 9 digit number)? We have setup the column to allow NULL's as we don'talways know employees bank details until later, so we do need to put them onour database without bank details initially.Also, if possible, can someone suggest a stored procedure or trigger i couldcreate that would fire a user-defined error message that would email anoperator if a bank account number changed?Many thanksDan Williams.

Recovering From Transaction Log Deletion In 6.5

Jul 20, 2005

I was trying to relocate my transaction log to a bigger drive usingsp_movedevice but I made a mistake in the syntax of the second parameterand put only the path, not the path and the file name.Now my database is marked as "suspect" and I get an error message in my logupon database start up saying that the log file cannot be open.Is there a way to have MS SQL 6.5 "forget" all the logs of this database,create new ones and restart the database? The logs contained nothingimportant, I had truncated them an hour or so before I made my mistake. Ijust want to make sure the data are still usable.When I look at the devices with sp_helpdevice, I can see a log that existand is hopefully in pristine condition and the one that doesn't existanymore.I looked in the archives of various newsgroups but couldn't find somethingthat correspond closely to my situation. I saw something similar but withMS SQL 7.0(http://groups.google.com/groups?hl=...om %26rnum%3D4)using sp_attach_db/sp_detach_db. What would be the equivalent with version6.5?Thanks!Charles--Charles-E. Nadeau Ph.Dhttp://radio.weblogs.com/0111823/

Auto Deletion Of Records Sqlserver

Aug 18, 2007

 Hi I am not sure if I am at right place, anyhow I hope I am :) Now the question: I am using an ASP.net Application with SQL-Server. I want to make a page so that it set the expiration time (date)  for certain record and once that time reaches, it deletes those records, or make any updates to the record (what ever applicable). I also want to control this auto deletion from my application, means that turn this On/Off whenever needed. I am not sure how to start this. I was told by a friend that I need to use triggers from SQL-server but I need some help. Can anyone help me out on this? RegardsMykhan
