Writing a Simple SQL Assembly,s vital to understand how the whole process works before you move on to the specific assembly types, which makes up the core of the book..Although the exact details vary, there are four steps involved in creating any CLR database object in SQL Server 2005:.You also saw how to get VS to do a lot of t

The SQL Server .NET Programming Model,em.Data.SqlClient namespace), supplemented by several classes in the new Microsoft.SqlServer.Server namespace. In this chapter, we provided a very quick ADO.NET refresher and introduced the following new objects:.We also looked very briefly at the new transaction framework in .NET 2.0 provided by th

CLR Stored Procedures,onstrate how to extend functionality of stored procedures beyond that to currently client-based areas that can gain a great deal by being rewritten as stored procedures. The first example of producing XML or an RSS feed could be linked with the job scheduling to produce monthly files. The second exa

User-Defined Functions,s, CLR functions allow us to take data from outside SQL Server and integrate it completely with SQL data—for example, incorporating the function as a subquery into a larger query..UDFs come in two distinct flavors, scalar-valued and table-valued functions, and in this chapter we looked at examples o

User-Defined Types,f UDTs, we can now create types of limitless complexity. Furthermore, we can encapsulate data validation logic within these types, thereby helping to improve our systems’ overall data quality. By using CLR UDTs, we will be able to define databases that are simpler, yet more flexible and functional.

User-Defined Aggregates,alization could be completed without any manual intervention..The building of aggregations is normally a straightforward process, but if you need to serialize any of the accumulative data that has to be passed as each row is processed, then this adds complexity. The main point to keep in mind is tha

Error Handling and Debugging Strategies,ebugging environment that would merit a book in itself, so here we had to content ourselves with a very quick look at its basic features. Even if you don’t have the full version of VS 2005, however, it’s still possible to step through code in a visual debugger, as SQL Server 2005 ships with a pared-
