Can you use the error handling with rollback transactions? The scenario is not to use MSDTC but instead build logic to roll back package if there is an error during the ETL process.
Yeah we can think of writing the custom code in the OnError event handler. So what will happen after each successful execution of a task in control flow, it will insert a entry to a sql table that this task has been completed. Now if a package fails then the control will move to OnError event handlder and there we can write code to read the details from the sql staging tables like what kind of tasks are already done so far, for example we inserted some data to a table thus we can use an execute sql task to delete or truncate those records, if we exported some files then may be we can write code to delete those files, so code in the OnError task will be very specific for that package only, same code can't be used in another package but the logic and idea will be same for each package that undo everything that has been done in the package so far and get that so far details from a sql staging table.
Great videos aqil... recently had interview questions regarding checkpoint file. Can we use same check point file in different environments.if yes how? Say package got failed in dev and we have checkpoint file created for that. Can we use the same file in prod to restart from failpoint. Please make a video
I think there will be different checkpoint files for dev and prod environment, because a checkpoint file is created if a package fails and it got deleted if the package runs successfully th-cam.com/video/6D3n0C1c1h4/w-d-xo.html
Test connection failed because of an error in initializing provider. The 'SQLNCLI11' provider is not registered on the local machine. this one for slowly changing dimension unable to establish connection sir
Right click on the connection manager in the lower pane, select edit. Now from the provider select the "Microsoft OLE DB Provider for SQL Server". Save the changes. And you should be good.
I just put an error by making Gender longer than it should, it didnt export the data nor put an error in the table I got this: Error: 0xC020902A at Data Flow Task, Flat File Source [2]: The "Flat File Source.Outputs[Flat File Source Output].Columns[Gender]" failed because truncation occurred, and the truncation row disposition on "Flat File Source.Outputs[Flat File Source Output].Columns[Gender]" specifies failure on truncation. A truncation error occurred on the specified object of the specified component.
Thanks for this great video. Just wondering why you put SourceName into the TaskName column when there is a System::TaskName available? In other words, what is the difference?

Fantastic!! Very clear teaching with great examples!
Thank you.
Perfect I like your teaching🤩
Thank you Parvane.
It worked like a charm! Thanks mate
You are most welcome Philipe de Souza Santos.

Try this method

Just answered my own question. TaskName would be the SQL task in the event handler.
@@javaguitarist Yes you are correct.
muy claro y preciso muchas gracias!
Muchas gracias.
Great video, brother
Thank you Tariq Adib brother.
We have multiple execute package task. Package should continue even there is a failure.How to achieve this? Do we have any video for this.
Yeah I think there is a video for this one
