SQL Server Development Today SQL Server RelationalEngineStorageEngineScheduler User Code (Procedures, Functions, Triggers) T-SQL … Purpose? Libraries? Tools? Skills? ? Extended sp? COM objects?

What can we do with CLR code? Common T-SQL objects can be implemented in CLR code User defined functions (and table valued functions) Stored procedures Triggers Additional objects can be implemented in CLR code User Defined Types User Defined Aggregates (MAX, MIN, SUM … )

When do we use CLR code? T-SQL code is great for CRUD operations CLR code is great for; General purpose Library support (.NET Framework) Tool support (Visual Studio 2005) Safety and (by scenario) performance “For the dirty jobs T-SQL doesn’t want to do”

Where do we use CLR code? Round trip “Distance” between the code and the data Scale up/out possibilities of different tiers Abstraction of the database technology Security requirements Set-based versus procedural code Possibilities for using shared code libraries in multiple tiers
