CQRS (Command Query Responsibility Segregation, http://martinfowler.com/bliki/CQRS.html) is a technique that separates data creation and modification from data querying. In a pure CQRS model a stored procedure would not both insert/update data and then retrieve data. Those are two distinct operations, and therefore separated.

Ok, I’ll do want to acknowledge that CQRS can complicate your application infrastructure, and that it does not make sense to use this pattern in any and every application you ever build. This is a pattern you would use when you have requirements for Resilience or massive scale.
