В® SQL Serverв„ў 2. Microsoft . NET Framework Common Language Runtime (CLR) environment. With new capabilities come new roles and responsibilities for the database administrator (DBA). This white paper helps the DBA determine the appropriate use of this new feature and also provides guidance about when other alternatives may provide better performance, flexibility, or capabilities. This white paper also offers guidance about suitable uses for the Database Engine . NET Framework Programming API.
It also suggests code, change, and release management processes that should be tailored to each DBA’s circumstances in order to ensure a professional and safe deployment. On This Page.

Microsoft. В® SQL Serverв„ў 2. Along with this breadth of programming options comes the need to consider which set of tools is appropriate for each task. Although many tasks can be accomplished in multiple ways, each has pros and cons.
Thus, finding the best tool for the job is critical for an application to perform and scale with load and growing business usage. Some of the questions the DBA needs to ask include the following: Should the system handle this data as XML or should it be shredded and stored relationally? Should this process, and all its complex pieces, be handled synchronously or asynchronously? Should this business logic, this calculation, or this added security option be handled in the client application, the middle- tier, or the back- end database? Should data analysis be handled in the relational database or through the Business Intelligence engine? Should the data transformation occur with the Integration Services ETL engine or in the database using transforms built with Transact- SQL?
Should complex business logic, traditionally running on middle- tier servers, remain in the middle- tier or migrate to the SQL Server platform? What mix of clients and servers are running in the infrastructure. Is there a need to support Windows clients, Unix clients, or both?
In most database development projects, the role of technology selection and the structural design of components that interact with the database falls on the database administrator (DBA). This is the person with final responsibility for managing and recovering that business data.
Most DBAs adopt conservative attitudes to new technology. This is a natural instinct because, along with the benefits offered by new functionality, new technology can introduce new risks to stability and integrity. The professional DBA usually manages the risk/benefit by ensuring that there is full testing and that they understand the new technology.
And, further, by taking the time to identify where it adds the most value and, perhaps more importantly, where it should not be used. As a result of this natural conservatism, the DBA may ask, “How do I turn that feature off until I understand it? The good news is that unlike previous releases of SQL Server, in this release many new features are off by default. Instead of leaving all features off permanently, a prudent DBA will tend to learn enough about the technology to determine where its use is appropriate and where its application makes the most sense.
There is no need to understand every line of code in every language that the developer might use, but there needs to be enough confidence to be able to provide great operational support, maintenance, and troubleshooting. Across many of these new features, the key to proper usage is understanding, impact isolation, and strong control. Introduction to . NET Framework Programming in the Database Engine. The SQL Server 2. SQL Server database tables and views: Use Transact- SQL to write code that runs within the database. Code can be written as stored procedures, user- defined functions, and/or triggers that can be regarded as stored procedures that are invoked on data change.
Use Microsoft. В® Visual C++В® to write code, an extended stored procedure, which runs within the database. Code that is written as an extended stored procedure appears to users as a stored procedure and is executed in the same way. Parameters can be passed to extended stored procedures and they can participate in transactions and return both results and return status. Use the sp_OA* (Object Access) system stored procedures to load and interact with COM objects.
Use other languages and middleware, such as ADO and ADO. NET, to write code that executes outside of the database and that passes in queries or invokes stored procedures and functions to access data. Each of these options has issues when the solution demands that data be integrated with functionality supplied by external libraries. For example, such as those provided with the . NET Framework, or that nontrivial mathematical operations be applied to the data, or if the requirement is for something more complex, such as a custom aggregation of data or a true user- defined data type. Each of the four options has limitations: Transact- SQL is excellent for set- based operations such as comparisons between tables but, due to the interpreted nature of the language, it can struggle to deliver good performance for computationally heavy tasks.
Another limitation is that unlike modern programming languages, Transact- SQL does not have support for private/public data encapsulation, so it is harder to implement clean interfaces between modules. Finally, SQL Server 2.
Transact- SQL. However, it is still susceptible to “untrappable” errors caused by missing objects or bad syntax that is easily handled by . NET Framework languages. Extended stored procedures are by their nature written in unmanaged code and execute within the context of the SQL Server process.
A greater level of programming competency is required to create code that does not inadvertently leak memory or generate unhandled exceptions that can crash the entire SQL Server process. Extended stored procedures cannot provide in- process access to the Microsoft .
NET Framework libraries without placing the server in an unsupported state. For more information, see the knowledge base article titled Using extended stored procedures or SP_OA stored procedures to load the CLR in SQL Server is not supported. The sp_OA* system stored procedures place limitations on the COM object. This requires that its interface be implemented in a compatible way and have further restrictions on the amount of data that can be passed to the COM object in a single call.
They can encourage inappropriate use of components that are not designed to be used in high- throughput scenarios, or that do not support multiple invocations by a single process. In the worst case, the component can attempt to display an error message window or other dialog on the SQL Server. External code can cause performance problems because data must leave the SQL Server process space and flow to the calling application. This data marshalling can be expensive for large volumes of data. None of the current options can be used to create first- class, custom aggregate functions or custom data types where first- class means running within the database as if it were a SQL Server primitive function or data type. With these limitations in mind, SQL Server 2.
NET Framework Common Language Runtime (the execution environment for managed code). Thus, it enables database developers to place managed application code inside the SQL Server that is safe, secure, scalable, and feature rich. Code can be written as follows: User- defined functions (scalar or table valued)Stored procedures. Triggers. User- defined aggregates. User- defined types. The mapping of user- defined functions, stored procedures, and triggers to objects written in managed code is fairly intuitive.
The CLR programs are accessed and execute in the same way as their Transact- SQL equivalents. However, user- defined aggregates and types are less intuitive and extend the options of the database programmer in new ways: User- defined aggregates allow the programmer to build custom aggregate functions (used in conjunction with the GROUP BY clause). This enables complex statistical and data analysis in the database engine.
User- defined types provide the programmer with the ability to define new types with custom behaviors. Combined with the power of the .
