如何使用DAAB建立连接并保持连接？

Question

I have a task ahead of me that requires the use of local temporary tables. For performance reasons I can't use transactions.

Temporary tables much like transactions require that all queries must come from one connection which must not be closed or reset. How can I accomplish this using Enterprise library data access application block?

Answer 1

Enterprise Library will use a single database connection if a transaction is active. However, there is no way to force a single connection for all Database methods in the absence of a transaction.

You can definitely use the Database.CreateConnection method to get a database connection. You could then use that connection along with the DbCommand objects to perform the appropriate logic.

Other approaches would be to modify Enterprise Library source code to do exactly what you want or create a new Database implementation that does not perform connection management.

Answer 2

Can't see a way of doing that with DAAB. I think you are going to have to drop back to use ADO.Net connections and manage them yourself, but even then, playing with temporary tables on the server from a client-side app doesn't strike me as an optimal solution to a problem.
