Why Stored Procedures are used?

By grouping SQL statements, a stored procedure allows them to be executed with a single call. This minimizes the use of slow networks, reduces network traffic, and improves round-trip response time. OLTP applications, in particular, benefit because result set processing eliminates network bottlenecks.

What is the best way to test a stored procedure?

You can just drag the stored procedures onto a DBML diagram and then call them as methods on your datacontext. Beats setting up ADO connections etc for a test harness. If you set up a test project in Visual Studio for example, you can simply test your procedures like methods on another object.

What is true about stored procedures?
