we had setup merge replication on 2 db servers. For some reason, the subscription started failing a month back with the error " invalid object sysmergexxxx on the subscriber. I did a reinitialize and now all the changes on the subscriber which werent synced got deleted. I have tried all 3 log recovery tools with no luck. Is there any hope of recovering data. the last backup on the subscriber was a month ago.
I am using SQL 2000. How can I get my transactional replication reinitialized after it has failed with several attempts.
I know one way of doing it through enterprise manager and specifying the subscription to reinitialize. But this will apply the snapshot and will take long time.
Is there a fast way of doing it?

From the SSMS GUI it is possible to re-initialize one or all subscriptions to a merge publication. This is done at the publisher.
How can I achieve these operations programmatically?
In particular, how do I initialize a single merge subscription from the publisher?
I have looked at the documentation for sp_reinitmergepullsubscription but it says that this proc must be run at the subscriber - which isn't much use when subscribers are disconnected for the majority of the time
I have a large number of merge subscribers and want to reinitialize all except one

Hello
I have an odd problem that is driving me nutz. I have a very simple SSIS package that imports a 5 colum flatfile into a sql Server 2005 Table.
When I created this package with the wizzard, it will execute perfectly fine and processes all rows into the destination table.
But when I hit F5 to execute it manually it will fail before inserting a single row.
The error it generates is (Spalte 5 is a Datetime in the format DD.MM.YYYY) :
Error: 0xC02020A1 at Datenflusstask, Source - Daten_NC_1_txt [1]: Data conversion failed. The data conversion for column "Spalte 5" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
Error: 0xC0209029 at Datenflusstask, Source - Daten_NC_1_txt [1]: The "output column "Spalte 5" (25)" failed because error code 0xC0209084 occurred, and the error row disposition on "output column "Spalte 5" (25)" specifies failure on error.

Hi,
I am getting this error when my ssis package is running
Data Conversion failed due to Potential Loss of data
the input column is in string format and output is in sql server bigint
the error is occuring when there is an empty string in the input. what should i do to overcome this
It is an ID field and should i convert to bigint or should i leave it as char datatype is it i a good solution or is there a way to over come this.
hi,
Im using merge replication.I have created one publisher with dynamic filtering and i have creted two subscribers from it(pull subscription).It was working fine.but after sysnchronizing 2-3 times data from some tables went missing
can any one help me....
thanks and regards

I am using SQL Server 2005.
I am trying to import data from CSV files into an SQL Server table using the Import wizard. The text qualifier is double quotes ("), column delimeter is a comma (,), first row has column names. One of the field name is "id", which is a GUID, whose datatype in SQL Server is uniqueidentifier. It looks like this in the file:
..."data","data","dbf7edf8-0ca8-4e53-91e3-5901cdc1819a","data"...
As you can see, there are no enclosing curly braces for the guid value. The DTS chokes on this and throws this error:
The value could not be converted because of a potential loss of data
If I add curly braces like this {dbf7edf8-0ca8-4e53-91e3-5901cdc1819a}, it imports with no problem.
Is there way to import this type of data, because there is no way I can edit these files, and I would prefer not changing the datatype of the id field?
Or is this a limitation of SQL Server?
Thanks,Bullpit
Hi All,I'm trying to track down a mysterious problem we're experiencing inwhich updates and inserts to tables in our mssql2k server appear to be'disappearing.'To explain our situation:We have a web page (written in ASP, if that's relevant) on which weaccept enrollment information.When that page is submitted, the form data is passed to a storedprocedure on our mssql2k server, which performs several operations,all of which are wrapped in a transaction.In particular, the stored procedure performs an update operation on arecord in one table (i'll call it TableA) and an insert into anothertable (TableB).If the procedure encounters a problem (ie after each update / insertoperation in the procedure we test for IF @@Error<>0) it performs arollback, performs a select similar to the one immediately below, andthen RETURNs.SELECT '1' as error, 'Unable to update TableA' as errormsgIf the procedure doesn't fail any of the @@Error tests, thetransaction is committed, and a membership number is SELECTed to bereturned.SELECT '0' as error, @memnum as membershipnumberThe @memnum variable is populated within the transaction.Back in the ASP page we test both for the proc returning an emptyrecordset, or for it passing an explicit value in the error field, andpush the page to an error page if either of these conditions are met.If, on the other hand, none of these conditions are met, and themembershipnumber field in the recordset is populated with a validmembership number, we push to a confirmation page.This confirmation page receives the membership number in a sessionvariable, performs a SELECT against TableB (the table that receivedthe insert during the proc) using that membership number in the WHEREclause, and the resultant recordset is used to populate theconfirmation details on that page. That recordset is also then used topopulate the details of a confirmation email, which is automaticallysent by the confirmation page.And now here's our problem: we've become aware of a handfull of peoplewho have gone through the enrollment process, have received theconfirmation email containing the information they supplied asexpected, but the data appears to be entirely missing from our tables.By that I mean that the record in TableA does not appear to have beenupdated (under normal circumstances that record should have hadseveral flags set, and several other fields updated with informationsupplied by the person enrolling), and the record in TableB does notappear to have been inserted.In essence, looking at our tables, it *feels* like the transaction inthe stored procedure for that particular enrollment hit a problem andwas rolled back. However, the evidence that we have in the form of theconfirmation email argues strongly that the data must have existed inour tables (particularly in TableB), if only for an unknown period oftime.We're kind of at our wit's end to work out what is going wrong withthese enrollments. From my understanding of transactions (and I couldwell be wrong) any changes to data (ie updates, inserts etc) containedwithin are essentially 'invisible' to any other operation (ie theSELECT that happens in the confirmation page) until the transaction iscommitted, implying that the effect of the update and insert shouldhave been 'permanently' successful if no error code is received and ifa valid membership number was returned. I ask, because someone in ourteam has suggested that maybe the operations in the transaction'lasted long enough' in the tables to have been visible for the SELECTon the confirmation page to have worked, but were then subsequentlyrolled back, explaining why the confirmation email is appropriatelypopulated and why the data then appears to be missing. However, as Isaid, this doesn't match my understanding of how transactions behave.Sorry for the length of this post, but I felt it was best to explainthis as best as I could.Does anyone have any advice they can give us on this situation? ie,are there any known problems with operations in transactions 'bleedingover' into tables, but then being rolled back at some later point?Does anyone have any thoughts or suggestions on how we can furtherdiagnose this issue?Truly, any help will be immensely appreciated...Thanks in advance,M Wells
View 2 Replies View RelatedI have a FoxPro dbf that includes From Milepost (f_mp) and To Milepost (t_mp) fields. These fields contain values between -1 and 9999.9999.

I have a Data Flow task which reads from an OLE DB Source (SQL Server 2005), uses a Data Conversion transformation to convert some field values, and finally outputs the result to distinct tabs of an Excel workbook. The task is failing with the following error:
There was an error with input column "oBBCompanyName" (2162) on input "Excel Destination Input" (57). The column status returned was: "The value could not be converted because of a potential loss of data.".
Using the Advanced Editor for the Excel Destination component, I examined the datatype of oBBCompanyName (ID = 2162) in the Input Columns list of the "Excel Destination Input" (identified with ID = 57). The Data Type is defined as DT_WSTR with Length = 255. The ExternalMetaDataColumnID = 203.
Also in the Advanced Editor for the Excel Destination, I examined the datatype of BBCompanyName (ID = 203) in the Extranl Columns list of the Excel Destination Input. The Data Type is defined as "Unicode String [DT_WSTR] with Length = 255.
What could I be overlooking that might be the root cause of this issue? The same error is occurring for different Excel Destination tasks in the data flow.

We have setup transactional replication across several databases using SQL Server 2000 spread across multiple sites in a fully connected network. There is one main table from which data is replicated from the publisher to the destination. Horizontal filtering is being used on this table to enable sending/routing of the records to the correct DB(site). It has been observed that the documents/records are getting lost between some sites. Say 10 documents are being sent fron the publishing database but only 5 are being received at the destination database although the sent history for all the 10 documents is available at the publishing database.
Can anyone guide on how to analyse and resolve this problem? Can unreliable network be the issue, If the network is not reliable and the connection is lost during replication how does replication ensure that no data is lost?
Hi,
I am getting the error below in my Flat File Source.
I've seen this error many times before, and have successfully resolved this problem in the past.
However, this time it's a little different. It's complaining about row 7 of myFile.csv, column 20. I have column 20 defined as a Numeric(18,6). It also maps to the Price field in the table, which is also a Numeric(18,6).
The problem is, on row 7 of myFile, column 20 is blank. That is, there's no data for row 7, column 20.
So, why should it care about this?? If it's blank, then how can you lose any data?? I have several other blank columns in this file, but they aren't throwing any errors. Just this one.
Thanks

Hi
I am having a bit of a difficult trying to understand this one. I had imported two tables around 2-300 rows each ran this in 64 bit scheduled it and it ran okay. I now introduced a 3rd table which if I change the true64bit to false it will run however if left true it keeps mentioning the output column of descr with a loss of data.
I did move it to 32bit and then ran the package it comes up as below. If I rememeber I can run this in 32bit mode which I'm sure will work hmm maybe!! but what I can't understand is why it works for two tables? is it something to do with the translation of the table or do I need alter the select statement?
Currently it is a select *

We had merge replication setup between 2 tables, Table A and Table B using SQL 2000. This was working 100%. The users asked to disable updated/deletes to both these tables if data existed on 2 other tables. Table AA and Table BB. We implemented it as follows:
1) Created Insert/Update/Delete triggers for Table A & B. It basically check for Table A is there a record in Table AA, if it exists, raise an error and don€™t commit.
2) Removed all foreign constraints from Table AA and BB
3) Added Table AA and BB to the current replication.
Then all hell broke loose, we got conflicts all other the place saying that Table AA cannot be updated because records does not exist in Table X. To our surprise we found triggers generated by Erwin in 1998 €“ that check for €œforeign contsraints€? and removed them immediately.
We continued to get conflicts but could see from the error messages it was generated by the triggers in point 1. We added the NOT FOR REPLICATION clause and everything has been running smoothly or so we thought€¦..
After 2 months we got a call that data is missing. It€™s random data and the only explanation I have is that replication caused that. My biggest reason for saying this is tracking the application audit trail I€™ve found that all the data missing was added during the period we had all the conflicts.
I need a solid explanation for this and can anyone confirm that this is possible?
We wanted to rebuild our main SQL server machine. How can we backup everything about the SQL server (such as all databases/objects and settings on security and users) and then recover them without any data loss?

Thanks!
Hi All,Further to my previous long-winded question about a situation in whichwe appear to be mysteriously losing data from our mssql2k server.We discovered an update statement, in the stored procedure we believeis at fault, after which no error check was being performed.Under certain conditions, this update is fired against the same recordin the same table as the immediately preceding update statement withinthe transaction. We are now suspecting that under some circumstances,these two updates get into a locking conflict that is eventuallyforcing the transaction to be rolled back.However, I'm still left with three questions.1) Where an update in a transaction gets locked, and an error isn'ttested immediately afterwards (ie no 'IF @@Error<>0' test is made),would the transaction proceed as normal?2) Most critically, would statements in the stored procedure thatappear after the COMMIT TRAN statement also be executed, even if anunresolved lock existed within the transaction?3) Assuming that (2) does happen, would a SELECT made on anotherconnection with a 'WITH(NOLOCK)' locking hint be able to see thechanges made in the locked transaction even if the server is set toREAD COMMITTED, and the SELECT takes place some time after the COMMITTRAN is issued? More to the point, given (2), how long would thelocked transaction survive before being rolled back after the COMMITTRAN has been issued? Is it possible that the COMMIT TRAN takes place,the transaction is flagged for potential rollback while a lockresolution is attempted, the stored procedure exists as thougheverything was fine, a subsequent SELECT (ie performed as one of thenext operations in the same application) using WITH(NOLOCK) 'sees' thechanges made by the transaction, reinforcing the impression that thetransaction succeeded, and then at some point thereafter the lock isdetermined to be unresolvable and the transaction is rolled back,making it seem as though the data disappeared, even though it had beenSELECTable via a different connection to the server?Thanks, by the way, to Simon and Erland for your advice on my previousquestions about this problem.Much warmth,M Wells

I'm trying to build a DTSX package that FTP's an XML file to the local file system and then imports it into an existing table.
My "Data Flow" for the package starts with an XML Source component and then goes to Data Conversion component and then to an OLE DB Destination component.
It all executes with out error and seems to work fine, but when I look at the data in the table after I've run the package it seems to have inserted the appropriate number of rows from the XML file but all of the column values are NULL.
All of the data in the XML file is surrounded by <![CDATA[ ]]> and I discovered that if I remove the CDATA wrapper by hand then it inserts the data properly. The only problem is that I'm not in a position to have the data provider remove the CDATA tags and some of the data in the XML file needs the CDATA wrapper or else it will not validate.
Anyone know of anything I can do to get the CDATA to import properly?
With my SSIS package, I want to import data from a flat file (TXT- delimited with ?) to a table in my database in sql server 2005. The problem is that I have a column of type datetime in my table. But as you know, the data in txt is string. First I created my package through importing data and using import/export wizard in management studio to my database and selecting flat file connection. There, I selected my txt file and column delimiter as ?, then suggested types for the columns. There it selects 8 byte signed integer type for the datetime column in my table. After these steps I create my package and execute it. But it does not put data in my table in the database. It gives the error of "The value could not be converted because of a potential loss of data" or "cast conversion failed" . I tried other types of date, timestamp, string but none of them was successful. What should I do to put data in my table from txts. Please can you help me urgently!!!
Thanks a lot
Hi,
I have a flat file that has a date column where the date fields look like 20070626, for example. No quotes.
The problem is that several of the date values are missing, and instead of the date value the field looks like this , ,
That is, there are several blank spaces where the date should be. The number of blank spaces between the commas doesn't appear to be a set number (and it could even be 8 blank spaces, I don't know, in which case I don't know if checking for the Len will produce the correct results, but that's another issue...)
So, similar to the numeric field blanks problem, I wrote a script to convert the field to null. This is the logic I used:
If Not Len(Row.TradeDate) = 8 Then
Row.TradeDate_IsNull = True
End If
The next step in my data flow after the script is a derived column where I convert TradeDate from 20070625 to 06/25/2007. So the exact error message I am receiving is this:
[OLE DB Destination [547]] Error: There was an error with input column "TradeDate - derived" (645) on input "OLE DB Destination Input" (560). The column status returned was: "The value could not be converted because of a potential loss of data.".
Do I need to add a conditional split after the script and BEFORE the derived column to redirect bad rows so they don't go to the derived column?
What am I doing wrong here?
Thanks
I'm getting a very strange potential loss of data error on my flat file source in the data flow. The flat file is fixed width and the column in question is defined as numeric [DT_NUMERIC]. The transform runs great if this column IS NOT A ZERO. As soon as a zero value is found, I get the error. It errors on the flat file source, so I haven't been able to use a data viewer to see what's going on.
Please Help!?

Hello,
I have a flat file source with ragged right format. It has three columns.
My package fails when the last column has null values.
It says "The value could not be converted because of a potential loss of data".
So tried lot changing row delimiter and column delimiter but to no avail.
So any idea on this is well appreciated.
Thanks in advance.
I have automated process, which synchronizes a transactional publication using initialize from backup approach. It drops subscriptions and puts them back again once the restore on the subscriber is completed.
Dropping the subscriptions causes a lot of blocking and deadlocking. I've decided to remove those steps, but it causes loss of data on the subscriber.
Is it a must to drop and re-create the subscriptions during such process? If not, how can I avoid the loss of data?
Why would I get these errors:
" SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E21.

I read related posts but could not figure out the error?

This was when I manually built the package.
I get the same error when using the Import/Export wizard
I am even using the "suggest types" button and have tried sampling the default number of rows (?200) and also 2000.
The type it suggests is DT_DATE.
But reading the BOL, this would appear to be the wrong type:
http://msdn2.microsoft.com/en-us/library/ms141036.aspx (obviously the right hand doesn't know what the left hand is doing)
seems to indicate that
DT_DBTIMESTAMP
is the correct value
(I cannot believe that they have different datatypes in SSIS than in SQL. I can't believe for a minute this is for all the hundreds of thousands of Oracle users who obviously switched to SSIS when they saw what a high quality product it is.)
I tried other DT_... values but no dice.
Can anyone help?
I always thought that Classic ASP was the worst product I've ever worked with from the Microsoft stable, but I was wrong.

This is to do with SQL 2005 merge replication (HTTPS if it matters)
Is there any difference between marking a subscription for reinitalizing via Snapshot Monitor, and having the subscriber mark it for reinitialization ?
Thanks

Hi,
I'm doing merge sync between SQL Compact on mobile devices and SQL Server 2005. I recently made a schema change on the server and noticed that it caused an error on the subscribers when syncing. I fixed the schema problem, and did a reinitialize all subscriptions with a new snapshot. On the mobile devices I forced a reinitialisation (upload changes first). I'm still getting the same error message, which relates to a schema change which is no longer relevant to the server db and snapshot. For some reason the subscriber dbs are trying to reapply the original problem schema change even though they're supposed to be reinitializing to a new snapshot. I've even tried dropping the affected tables from the publication, and reinitializing all subscriptions with a new snapshot, but still the same error on the subscribers. Does anyone know why the subscriber dbs are still trying to apply a now defunct schema change (on tables which no longer exist in the publication)? Is there any way to flush this from the subscribers so they correctly pick up the new snapshot?
Regards,
Greg McNamara
We have a two SQL Server 2005 databases set up using Transactional Replication. My manager has asked me to set it up to replicate constraints (default, fk, et) on the tables in the main publication. I said sure, I can do it, but I will have to re-initialize the subscription. He said there was a way to do it without re-initializing the subscription. I cannot find anything in my research to indicate that there is a method to do so (via call sp_ functions, etc). Is it indeed possible to replicate constraints on replicated tables without re-initializing the who subscription? The reason he does not want me to perform a re-initialization is that we are a few weeks before moving into production, and a full re-initialization takes 1.5 days, which would impact system availability.
Thanks in advance for any advice.
Hi all,
I'm admitedly a bit new to the world of replication, so please bear with me. I've got two SQL Server 2000 servers running in different locations. Server A does transactional replication over a push subscription to server B. If I need to make a minor change to one of the replicated tables (for example, dropping a no longer used column or changing a varchar field's length) do I need to drop the subscription, make the changes and then re-initialize the schemas and data?
For minor changes, I really hate having to knock out the site runnign off server B while the subscription is re-initialized and data is bulk copied back over. If I want to just make the changes manually on both servers will that cause problems down the line?
Any help is greatly appreciated.

I have a stored procedure that receives an input parameter of ReporID and then sends back the appropriate dataset to the data-driven subscription. In the stored procedure, there is some concatenated sql in producting the final select statement to send to the subscription, but it is generating the following error:
The dataset cannot be generated. An error occurred while connecting to a data source, or the query is not valid for the data source. (rsCannotPrepareQuery) Get Online Help
Insert Error: Column name or number of supplied values does not match table definition.
Because there are some optional columns that need to conditionally appear based on the report, I can't avoid concatenation. My only other option is to have hundreds of individual tables to source all our reports, which I don't have time to manage.
Please let me know how I can allow the data-driven subscription setup process to discover the columns for my concatenated SQL so I can seutp my schedules based on the single stored procedure with all my logic nested in my table structure.
Thanks.
