What's the different between Distributed database transaction and cross database transaction in SQL Server.
I know that Distribute database transaction is a transaction between multiple database and can use by following query :
BEGIN DISTRIBUTED TRANSACTION
...
COMMIT TRANSACTION
回答1:
A Cross database transaction occurs between 2 or more databases on the same server. It does not require the involvement of a DTC (Distributed Transaction Coordinator)
A Distributed database transaction occurs between 2 or more databases hosted on multiple servers. DTC (Distributed Transaction Coordinator) services are required on each participating server.
