I'd like to rollback a change I made recently in TFS. In Subversion, this was pretty straightforward. However, it seems to be an incredible headache in TFS: Option 1: Get Prior Version Manually get prior version of each file Check out for edit Fail - the checkout (in VS2008) forces me to get the latest version Option 2: Get TFS Pow...
The in-house application framework we use at my company makes it necessary to put every SQL query into transactions, even though if I know that none of the commands will make changes in the database. At the end of the session, before closing the connection, I commit the transaction to close it properly. I wonder if there were any particu...
For some reason I am having troubles with a DBI handle. Basically what happened was that I made a special connect function in a perl module and switched from doing: do 'foo.pl' to use Foo; and then I do $dbh = Foo->connect; And now for some reason I keep getting the error: Can't locate object method "rollback" via package "...

Well basically I have this script that takes a long time to execute and occasionally times out and leaves semi-complete data floating around my database. (Yes I know in a perfect world I would fix THAT instead of implementing commits and rollbacks but I am forced to not do that) Here is my basic code (dumbed down for simplicity): $data...
I'm asking myself if it is possible to check if in ADO.NET the current transaction can be rolled back.

I am using .NET 2.0 and SQL Server 2005. For historical reasons, the app code is using SQLTransaction but some of the stored procedures are also using T-SQL begin/commit/rollback tran statements. The idea is that the DBTransaction can span many stored procedures, which each individual sproc controls what's happening in its scope - in eff...
I am working on some schema changes to an existing database. I backed up the database to get a dev copy, and have made my changes. I will be creating a single roll script to migrate the changes on the production machine in a single transaction. Is there a best practice for creating a rollback script encase a deployment issue arises? B...
Given an example of calling two web services methods from a session bean, what if an exception is thrown between the calls to two methods? In the case of not calling the web services the transaction will rollback and no harm done. However, the web service will not rollback. Of course, even with a single web service there is a problem. Wh...

One of his concerns is how to enforce the 30-day trial period and make it immune to "system rollback" software like Time Machine. Question: What is the industry best practice for preventing the use of "system rollback" sof...
I have a process which involves sending a JMS message. The process is part of a transaction. If a later part of the transaction fails, a part that is after a previous part that sent the message, I need to cancel the message. One thought I had was to somehow set on the message that it is not to be picked up for a certain amount of time, a...

I've got an IDbTransaction in a using statement but I'm unsure if it will be rolled back if an exception is thrown in a using statement. I know that a using statement will enforce the calling of Dispose()...but does anyone know if the same is true for Rollback()? Update: Also, do I need to call Commit() explicitly as I have below or wil...

Couldnt find the answer to this in the Hibernate Session/Transaction API, or in the Hibernate reference documentation. Or do you recommend me to close that Session object, open a new S...

If a sql call fails, say to timeout due to deadlock, the transaction can turn into a zombie transaction-- I guess either my code or framework code does the rollback. The SqlTransaction isn't null, but it is a zombie can throws an error if you try to do a Rollback(). I can't find the .IsZombie property. // Make sure the transaction is ...
