Hi all,

I have a general question about the snapshot isolation level in SQL Server 2005 and the MS DTC.

Let's say I set a database's transaction isolation level to snapshot:

USE Master

Now, say I have simple query along the lines of:


But this query is, for arguments sake, being passed in by the MSDTC.

Now, according to the BOL article for "Choosing Row Versioning-based Isolation Levels", snapshot isolation does not support distributed queries.

Does this mean that even our simple query, passed through MSDTC will be considered a distributed query and so be rejected?

Ya know, just a quick question.

Hi there,

did you ever get an answer to that question?? we too are using MSDTC, but on a single DB (so it's not really distributed), but the MSDTC can wrap all of our .net calls into one transaction. anyways, we wanna upgrade to the Snapshot isolation but appears that the MSDTC (at least with EnterpriseServices) does not support it...

If you got passed your problem, I would love to hear how. thanks!!
