Blog de John Cardozo: Usar una DLL desde SQL Server 2005. Execute .NET Code under SQL Server 2005. Download source - 7.95 KB Introduction First of all, I would like to congratulate the Microsoft Development Team for their superb and innovative technology using which we can use managed code written in any of the .NET supported languages in Microsoft SQL Server 2005 Stored Procedures.

Execute .NET Code under SQL Server 2005

If I make it simple, then "Now you can call any function written in .NET class library in your SQL Server stored procedure". This technology will allow us to use the features of .NET language with the extendibility of SQL Server. Programando a medianoche SQL CLR sobre SQL Server 2008 y Visual Studio 2010.

Usando librerías .dll de .NET en SQL-Server2008. Aunque normalmente no se recomiende tener la lógica de negocio en el lado del servidor de la base de datos, en algunos casos puede resultar interesante el hacerlo.

Usando librerías .dll de .NET en SQL-Server2008

Microsoft, en su empeño (por otra parte loable) de lograr una integración total entre sus servicios, nos permite utilizar nuestras .dll creadas en .NET (sea en VB.NET o en C#.NET o en C++) dentro de nuestra base de datos SQL-Server como “código gestionado”. Iré construyendo poco a poco un ejemplo para que veáis, paso a paso como se realiza esto. Lo primero es activar clr para que nos permita la integración con .NET tal que así: Seleccionamos la base de datos a utilizar, configuramos clr como ‘enabled’ (armado, activado) con el parámetro 1 y ejecutamos reconfigure para que el cambio tenga efecto. Acuérdate de poner el parámetro (en este caso 1) y de ejecutar reconfigure. El primer paso está realizado. Compiling and Deploying a CLR Assembly. This topic provides an overview of the namespaces and libraries required to compile database objects using the Microsoft SQL Server integration with the Microsoft .NET Framework common language runtime (CLR).

Compiling and Deploying a CLR Assembly

The topic also shows you how to write, compile, and run a simple CLR stored procedure written in Microsoft Visual C#. The components required to develop basic CLR database objects are installed with SQL Server 2005. CLR integration functionality is exposed in an assembly called system.data.dll, which is part of the .NET Framework. This assembly can be found in the Global Assembly Cache (GAC) as well as in the .NET Framework directory. A reference to this assembly is typically added automatically by both command line tools and Microsoft Visual Studio, so there is no need to add it manually. The system.data.dll assembly contains the following namespaces, which are required for compiling CLR database objects: Cómo usar regular expression en SQL Server. Desde Microsoft SQL Server 2005 en adelante, existe la manera de acceder a funciones, escritas usando las librerías de .Net, desde stored procedure, funciones, triggers, etc..

Cómo usar regular expression en SQL Server

¡Esto nos dá un poder increíble ya que las posibilidades son infinitas! Crear un ensamblado. Adding an Extended Stored Procedure to SQL Server. A DLL that contains extended stored procedure functions acts as an extension to SQL Server.

Adding an Extended Stored Procedure to SQL Server

To install the DLL, copy the file to a directory, such as the one that contains the standard SQL Server DLL files (C:\Program Files\Microsoft SQL Server\MSSQL12.0.x\MSSQL\Binn by default). After the extended stored procedure DLL has been copied to the server, a SQL Server system administrator must register to SQL Server each extended stored procedure function in the DLL. This is done using the sp_addextendedproc system stored procedure. The first parameter of sp_addextendedproc specifies the name of the function, and the second parameter specifies the name of the DLL in which that function resides.

It is recommended that you specify the complete path of the DLL. The name of the function specified in sp_addextendedproc must be exactly the same, including the case, as the function's name in the DLL. Using CLR to access .NET functions in SQL Server (example to execute aspx pages from asp) - Marker Studio. Summary: An example of how we can create a function in .NET and then use them in SQL Server.

Using CLR to access .NET functions in SQL Server (example to execute aspx pages from asp) - Marker Studio

This example runs an aspx page (useful for people wanting to call aspx pages from asp) How do we implement this functionality? In order to use CLR we have to: 1) Write a .NET class with a public function 2) Compile the class to a DLL 3) Register the DLL with SQL Server 4) Create a SQL Server function to access the .NET function Creating an example function and DLL To provide a simple example that you can use, we need to first create a new project.
