I have a web application and all of its queries begin with
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
Is there any way to create all connections with this isolation level? Can I implement this to connection pool in web.config or somewehere else?
You can find this option in the properties of the database (if you are using SQL Server Management Studio) or alternatively using the ALTER DB statement.
EDIT: Thanks to @Martin Smith, the command doesn’t do what you want it to. See here for more details (differences between Read Committed with Snapshot off and Read Uncommitted).
