Prerequisites

To complete this walkthrough, you must have Visual Studio 2012 installed. You must also be able to connect to a database server or a LocalDB database on which you have permissions to create and deploy a database.

Create a script that contains a database schema

To create a script from which you can import a schema

  1. In Visual Studio, on the menu bar, choose File, New, File.

    The New File dialog box appears.

  2. In the Categories list, choose General.

  3. In the Templates list, choose Sql File, and then choose the Open button.

    The Transact-SQL Editor opens.

  4. Copy the following Transact-SQL code, and then paste it into the Transact-SQL Editor.

    PRINT N'Creating Sales...';
    GO
    CREATE SCHEMA [Sales]
        AUTHORIZATION [dbo];

  5. On the menu bar, choose File, Save SqlQuery_1.sql As.

    The Save File As dialog box appears.

  6. In the File Name box, enter SampleImportScript.sql, and then choose the Save button.

    Save the file to any location on your computer, but make note of the location because you must use it in the script in the next procedure.

  7. On the menu bar, choose File, Close Solution.

    Next, create a database project, and then import the schema from the script that you've created.

Create a database project and import a schema

To create a database project

  1. On the menu bar, choose File, New, Project.

    The New Project dialog box appears.

  2. Under Installed, expand the Templates node, expand the Other Languages node, choose the SQL Server category, and then choose the SQL Server Database Project template.

    Note

    The Other Languages node doesn’t appear in all installations of Visual Studio.

  3. In the Name box, enter Small Database.

  4. Select the Create directory for solution check box if it isn't already selected.

  5. Clear the Add to source control check box if it isn't already cleared, and then choose the OK button.

    The database project is created and appears in Solution Explorer.

    Next, import the database schema from the script.

To import a database schema from a script

  1. On the menu bar, choose Project, Import, Script.

  2. On the Welcome page, review the text, and then choose the Next button.

  3. Choose the Single File option button, and then choose the Browse button.

    The Import SQL Script dialog box appears.

  4. Open the folder where you saved the SampleImportScript.sql file, choose it, and then choose the Open button.

  5. Choose the Finish button to close the Import SQL Script dialog box.

    The script is imported, and the objects that the script defines are added to your database project.

  6. Review the summary, and then choose the Finish button to close the Import SQL Script File dialog box.

  7. In Solution Explorer, verify that the script files (.sql) were imported into the Sales, Scripts, and Security folders of your project.

  8. In SQL Server Object Explorer, verify that the database appears under the Projects node.

    At this point, the database contains only system objects, such as tables and stored procedures. After you deploy the database, it will contain the user tables and stored procedures that the scripts define.

Deploy the database

When you choose the F5 key, you deploy (or publish) the database to a LocalDB database by default. You can deploy the database to a different location by opening the properties page for the project, choosing the Debug tab, and then changing the connection string.
