Abstract
The present invention describes an efficient and fast framework for implementing table-valued functions (TVF's) in a relational database server. The framework provides desirable extensibility properties and has the ability to minimize performance degradations by integrating tightly with the optimization infrastructure in a query processor. The present invention also enables a managed execution environment (MEE) such as the Common-Language-Runtime (CLR), to efficiently and dynamically extend the logic of the database engine with user-supplied code.
