I would like to know if there is a way to SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED on a connection string to SQL Server. I want to do this for the data source connections within SSRS so the queries do not cause deadlocks on simple select statements. Or, is there a way this can be setup in SSRS? Obviously I could add NOLOCK hints to all of the SSRS queries but I don't want to do that.
I've added SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED to the beginning of all my SSRS queries. Admittedly it's annoying to have to remember and a pain if you have to go back and update tons of reports, but it works like a charm in my environment.

why do you want to read uncommited data? what are frequencies of DML operations in db?do you know the issues related to this?
