Walkthrough: Creating a SQL Server Compact Database

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

This walkthrough demonstrates how to create a new SQL Server Compact database file that is based on the Customers and Orders tables in the Northwind sample database.

This walkthrough illustrates the following tasks:

  • Creating a new Windows-based application.

  • Creating a new local database file and adding it to a project.

  • Creating database tables and relationships by using the data design tools in Visual Studio.

In order to complete this walkthrough, you will need:

Because you will create a database that is based on the empty database template, you need a project in which to create the database.

NoteNote

Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Customizing Development Settings.

To create a new Windows-based application

  1. In Visual Studio, on the File menu, point to New and then click Project.

  2. Name the project SampleDatabaseWalkthrough.

  3. Click Windows Forms Application and then click OK. For more information, see Developing Client Applications with the .NET Framework.

    The SampleDatabaseWalkthrough project is created and added to Solution Explorer/Database Explorer.

To add a new database to the project

  1. On the Project menu, click Add New Item.

  2. Select Local Database in the list of available templates.

  3. Type SampleDatabase in the Name box.

  4. Click Add.

    The Data Source Configuration Wizard opens with the new SampleDatabase.sdf file chosen as the data connection.

  5. Click Next.

  6. Click Next again to save the connection string to the application configuration file.

  7. Click Finish on the Choose Your Database Objects page. (No database objects are available because this is a new database.)

    SampleDatabase.sdf and SampleDatabaseDataSet.xsd are added to the project.

To add tables to the database

  1. Open Server Explorer/Database Explorer by clicking Server Explorer/Database Explorer on the View menu.

  2. Expand the SampleDatabase.sdf node under the Data Connections node.

  5. Paste the Northwind Orders table data from the Clipboard.

Now that you have created a sample database containing data, you should make a copy of the database in its original state so that you can restore the data if you need to.

To save the sample database

  1. On the File menu, click Save All.

  2. On the File menu, click Close Solution.

  3. Browse to the SampleDatabase.sdf file in your Projects folder, and copy it.
