This walkthrough uses assemblies that might not be installed by default in your project. In the Location box, verify where you want to store your project files. In the Templates pane, click Console Application. In the Project types pane of the New Project dialog box, click Visual C#. On the Visual Studio File menu, point to New, and then click Project. In this first task, you create a Visual Studio solution that contains the necessary references to build and run a LINQ to SQL project. Specifying the connection to the Northwind database.Ĭreating a simple query to run against the database.Įxecuting the query and observing the results. This walkthrough consists of six main tasks:Ĭreating a LINQ to SQL solution in Visual Studio.ĭesignating properties on the class to represent database columns. After you have downloaded the database, copy the file to the c:linqtest5 folder. For instructions, see Downloading Sample Databases.
Northwind database sql queries download#
If you do not have this database on your development computer, you can download it from the Microsoft download site.
This walkthrough requires the Northwind sample database. Create this folder before you begin the walkthrough. This walkthrough uses a dedicated folder ('c:linqtest5') to hold files. This walkthrough was written by using Visual C# Development Settings. For more information, see Personalizing the IDE. The Visual Studio edition that you have and the settings that you use determine these elements. Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. Normally speaking, you would use the Object Relational Designer to create your object model. This walkthrough is code-oriented by design to help show LINQ to SQL concepts. You will then create a simple query to list customers who are located in London. You will create an entity class that models the Customers table in the sample Northwind database. This walkthrough provides a fundamental end-to-end LINQ to SQL scenario with minimal complexities.
However, in this case, I wanted to see if I could use SQL queries to not only download the data that I needed, but to calculate some basic summary stats that would be useful.-> On the Add New Item window, select LINQ to SQL Classes under the Templates section and name it Northwind.dbml as we will be using the Northwind database for the sample queries This will do a couple of things.
