Saving Some Data Despite A Rollback Transaction Command
Sep 12, 2007
I am working on reformating, cleaning, adding derived elements, etc... on data with no data validity checks on the front-end, source data. Its an incremental process where each month I add new data to the prior months' history. Sometimes the new monthly source data "surprises" me -- different values, different data definitons, etc. than expected.
I deal with these surprises by accumulating the fields/values that are unexpected after converting them to varchar with some explanatory language into a table [program_newdataprobs]
If there are any records in [program_newdataproblem] I rollback the transactions so the prior months' history remains unaltered. The problem is I then "lose" the contents of [program_newdataproblem] which I would like to hand to the source data people to troubleshoot.
I have tried the following:
Begin Transaction tran1
.... code that reformats data here
if (select count(*) from program_newdataproblem)>0
BEGIN
Begin Transaction tran2
select * into #t1 from program_newdataproblem
Commit Transaction tran2
Rollback Transaction tran1
insert into program_newdataproblem
Select * from #t1
END
This bombs because because #t1 no longer exits
Any way I can "keep" the data from program_newdataproblem when I Rollback the other transactions? (without having to store the history in separate tables that I can then access if new data errors occur)
I am having a application in which from the front end i am saving details of three different things
i.Enquiry Details
ii.Parts Details
iii.Machine details
i am saving the Enquiry detail in a data table,Parts Details in a data table and machine detail in a data table and finally i am adding the three data tables into a single data set and passing the data set to data access layer there i have three insert command one for each data table in my case the enquiry data table will be saved first and then the next two details will be saved and i am saving the details in three different tables in the database, my problem is some times the enquiry details will save to the database and while saving the Parts details there may be some exception and i will throw an exception in that case the enquiry details will be saved and the remaining two details are not saved(Which are also part of the same Transaction).I wanted to know about how to call the transaction function in case of Data Access Layer.
I'm receiving the below error when trying to implement Execute SQL Task.
"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'
I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.
does Sql server has command equalent to Rollback to in Oracle. That means when you do some update operation and i want to revertback the original record. If so what is that command.
I just made a transaction which writes and reads some data from a database as one unit. Now, I would like to know, what happens, if this transaction does not commit, but instead performs a rollback? Should I use a boolean loop which keeps on trying the transaction until it commits or is there an alternative? I would appreciate any suggestions or help!
If someone could help me with this I will be in debt to you!I am a .net developer who is working on a system that has a sql server2000 backend. On the weekends, I work from home and I have MSDE on mylaptop. This morning I went to update the main SQL server as I addedsome new views .. however I managed to import the data too!!Therefore I have overwritten my local data to the main sql serverdatabase, which has ressulted in loss of loads of work!Can I rollback to the version before I exported my data from MSDE to themain SQL server. I did the export by using enterprise manager and rightclicking on the table on my local msde and then sending it to the realsql server!Please please please help??*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Hi everyone, In the following T-SQL code snippet,when I attempt to insert more than one record I encounter an error because of the following trigger but I have some doubts about the performation of ROLLBACK TRANSACTION in here. So there is only one transaction occured in the specified table that contain both trigger and the specified table however I supposed that when we call ROLLBACK TRANSACTION, the transaction is aborted. But the code run the Raiserror statement which is located in after the ROLLBACK TRANSACTION statement. So why do this code( Raiserror) is run ? Should not it be terminated because of the ROLLBACK TRANSACTION statement ??

I am moving some code that was created in visual studio 2002 into Visual Web Developer 2005 express edition and am getting a warning on some of my code before compilation. The warning is "Variable lSqlTransaction is used before it has been assigned a value. A null reference exception could result at runtime". I experienced no problems in vs2002. The offending line is the rollback command within the exception. If I move it out of the exception it no longer flags the warning, if I move it after the throw statement it now longer flags the warning. Any help appreciated. Heres the code Public Shared Sub ExecuteNonQuery(ByVal lSQLCommand As SqlCommand)
Dim lSQLConnection As New SqlConnection(SQLConnString(enmSQLDB.enmSQLDB_TPSDB)) Dim lSQLTransaction As SqlTransaction
Try '----------------------------------------------------- 'Try and open the database '----------------------------------------------------- lSQLConnection.Open()

In VB 6, using ADO, SQL Server 2000In my VB program I use the connection object (abc)to begin a transaction.abc.BeginTransI then, in my VB App, using ADO, execute multiple stored proceduresinserting records into temp tables ##Meetings,reading them, and then finnaly executing (from my VB appusing ADO) as stored procedure that inserts recordsinto a non-temp table.I then have a abc.CommitTransWhat if my VB program crashes before thecommittrans is executed, I assume that the transactionis rolled back, even though no explicit rollbackis issued, because my VB program has crashed.Thank You for your help,Laurence NuttallProgrammer Analyst IIIUCLA - Division of Continuing Education
We are loading data from one extract file in to 4 different database tables. When we are loading if the first table gets loaded without any issues and the second table loading gives any issues, we need to rollback the data loaded in to the first table also.
In the package for achieving this, we are using Sequence container. In the sequency container we are having 4 different tasks for loading data to 4 different tables from the same extract file. We also tried setting the different transaction options given in the properties box of the packages, container and tasks.
Also we tried the properties by setting as mentioned in the Test# 7 and 8 in the following URL
I have a Dataflow where I insert data from SQL to Oracle and SQL Connection needs to have RetainSameConnection = TRUE. I have Oracle Services for Microsoft Transaction Server installed and I can rollback the transaction only if SQL Connection has RetainSameConnection = FALSE and TransactionOption = Required. Is there any possibility to rollback the Oracle transaction with having SQL RetainSameConnection = TRUE and TransactionOption = Supported?
I was running a stored procedure it was suspended for about 11 hours so I decided to kill it now its in Killed/Rollback stage for 12 hours and when check the status of roll back it says "Estimated rollback completion: 0%. Estimated time remaining: 0 seconds." its using up CPUTIME 380000 and DiskIO 970000. How to do I stop this co.mpletely
When I write code for a multiple statements transaction do I need to check 'if @@ERROR > 0 ' after each SELECT, INSERT, DELETE or UPDATE statement so that the 'rollback tran' statement can be given, or SQL server will automatically rollback the transaction and we don't need to check for @ERROR > 0 ?
Hi everyone, I am reading about the Rollback transaction but I'm not sure if it's the feature I need. My application is going to update a few tables, but my programmer said that it will be done using more than 1 transaction. For example, if I want to create a new employer with all the detailed informations, tables will be filled when the user complete the insertion of a part of data. If he decides to abort the operation, i'd like to delete all the values inserted before with the other queries. Is it possible to create a "savepoint" and roll back all transactions processed from this savepoint?
Hi,I have a problem. When my computer loses connection toserver during transaction it is rolled back automaticlyby server after 2-5 minutes. During the time a can resetmy computer, run my program again and I can seedata from not commited transaction becouse I have toset isolation level to read uncommited.How to force the server immediately rollback transaction?TIAclint
Hello, I have a stored procedure that updates my table with values entered in a datatable in my windows app.
An error occurs 1/2 way through the update process. I assumed that by implementing the rollback transaction command that the inserted lines would not be saved to my db. This is not the case.
I will elaborate a little more on what I need. From my windows app I have a datatable with 100 new rows that need to be written to my db. This I can do. However, a problem crops up should there be an error during the transfer. Let's say I have 100 rows in my datatable in my windows app, and row 57 causes an error, what is happening is that rows 1-56 are committed and 57-100 are not. What I need is for 1-100 to NOT be committed to my DB should there be a snag along the way. I need a code sample as I'm having way too much difficulty with this as is.
The basic code that copies to my db(sans rollback): BEGIN SET NOCOUNT ON INSERT INTO userprofile (uid, uname, ustatus) VALUES @userid, @username, @userstatus; END
First of all, this is my first time using SQL SERVER 2005 express, before that i'm using POSTGRESQL database.
I would like to know how what's the equivalent command for "BEGIN","ROLLBACK","COMMIT", these are the POSTGRESQL COMMAND use to start transaction, rollback transaction and commit transaction.
Example when i use this kind of command is . I need to insert data into 3 table. before insert into table1, i issue "begin", start to insert data into table1, if table1 no error, then i proceed to table 2 and table3. if table2 and table3 no error. then issue "commit" to commit the changes. but if any error happen between table1 and table 2 or table 2 and table3, i will issue "rollback" to roll any changes that i make to table1, table2 and table3.
Maybe some one can teach me how to achieve using SQL SERVER 2005 EXPRESS.
Hi all, I have a program that needs to delete records, then re-insert new records to a table. But I need to rollback the transaction IF the insert is not success (error occured). The delete and insert are in 2 difference stored procedure (which have rollback transaction) that calling from 1 stored procedure. My problem is that if Insert is not successful, but the records already deleted previously. How can we rollback the delete transaction when insert is not successful? Note: if possible, I don't want to delete the records AFTER the insert is successful, or create a temp table to stored the deleted records ======================================= create stored procedure combine_sp as begin call delete_sp -- have rollback transaction in the delete_sp -- what to do if following has error occured, but we already deleted the records above? call insert_sp -- have rollback transaction in the insert_sp end go ======================================= Thanks a lot.
I have a transaction that calls one other sproc and also executes another set of queries, but for some reason I'm getting error 266: "Msg 266, Level 16, State 2, Procedure AddUserHaveTag, Line 26.

We have an order posting stored procedure that's been executing for 14 hours now. This procedure has simple update statements but all the tables updated have triggers which update other tables with triggers and so on. This procedure hasn't commited yet. I have a full database backup from last night and transaction log backup from this morning while it was running. I want to kill this job and restore database from last backup. Only thing I am afraid of is that it will take too long to roll back which I have no estimate of time. Is there any faster way to get rid of all the uncommited transactions? Has anybody rolled back such a massive transaction? Any idea on how long it can take? Can it affect the overall server performance as this is the main production ERP server. I can see in profiler that this procedure is still running and not hung.
I have a wrapper stored procedure ProcMain_wrapper that executes in one main dataabase and it calls child stored procedure in multiple databases. Does the rollback occur in all the databases if the stored procedure fails in any one of the multiple databases?

I'm trying to save several records to an SQL Server 2000 database. The records are in a 1:Many relationship; i.e., there is one record that goes into a parent table, and several that go into a child table. I have to do this with stored procedure(s) that constitute one transaction. Can anyone tell me how this might be done?Thanks!

i haven't had an opportunity to do this before. I have nested stored proc and both inserts values into different tables. To maintain atomicity i want to be able to rollback everything if an error occurs in the inner or outer stored procedure.
