What is the txn parameter supposed to do or be used for?
I'm just passing an empty variable of type Object to this parameter and the method call is working fine...but I'm interested in knowing what its there for.
Thanks
JamieIt is the transaction context you want to use for any work done in that connection. Think of DTC, you need a context that can be supplied to all connections that make up that transacction so all work is marshalled together, well this is that handle.
Passing null will pretty much always work. If you have a transaction context then pass it otherwise don't worry.|||

Cool, that makes sense. I figured it was something I didn't have to worry about.
cheers Darren.

A follow-up on this: Ive been writitng a custom dataflow source that analyzes flatfiles by various properties (filesize, width etc.). The component works well when i have a stable flatfile connection. But when i do a for-each file in folder enumeration i cant get the updated connection information (ie filepath) from my component, it will always run against the first path passed by the connection manager. Any ideas on this?|||I've had issues with class level variables and loops since the class is only created once, that was a task though. Simple answer is I don't know, and don't have a suitable component to test with easily, but if you debug the component it should be very simple to work out what is going on. Put a break point on AcquireConnections for a start and see how many times it is called.
Another obvious test would be to add a script component, and make that consume the same connection, and just MsgBox out the connection string.
What do you get?|||
I have an SSIS package with its TransactionOption set to 'Required'. A data flow in the package has a script component that performs updates to a database table. The TransactionOption on the data flow is set to 'Supported'. However the script component does no get enlisted to the transaction because the updates made in the script component do not get rolled back when the package fails.
I'm thinking that I need to pass this 'transaction handle' to the AquireConnection method of the connection used by the script in order for the script to become part of the overall transaction.
In regard to your reply about transaction context. How do I determine it? I have no idea what value I should be passing. I am new to Sql Server beginning with Sql Server 2005. I have no background with DTC.
Thanks.
