Visual Studio 2013 Database Tutorial: Working with Databases342

Visual Studio is a powerful integrated development environment (IDE) that can be used to develop a wide variety of applications, including database applications. In this tutorial, we will learn how to use Visual Studio 2013 to create and manage databases, and how to work with data in those databases.

Creating a Database

To create a new database in Visual Studio 2013, open the File menu and select New > Project. In the New Project dialog box, select the Database category, and then select the SQL Server Database project template. Enter a name for the project and click OK.

The new project will contain a single database file (.mdf) and a log file (.ldf). The database file stores the data in the database, while the log file stores information about changes made to the database.

Connecting to a Database

Once you have created a database, you can connect to it in Visual Studio 2013 by opening the Server Explorer window. The Server Explorer window is located in the right-hand pane of the Visual Studio window. To open the Server Explorer window, click the Server Explorer button on the toolbar, or press Ctrl+Alt+S.

In the Server Explorer window, expand the Databases node and then right-click on the database that you want to connect to. Select the Connect command from the context menu.

Working with Data

Once you are connected to a database, you can start working with the data in that database. To view the data in a table, double-click on the table name in the Server Explorer window. The data will be displayed in a grid.

You can add new rows to a table by clicking on the New button on the toolbar. You can also edit the data in existing rows by double-clicking on the cell that you want to edit.

To delete a row, select the row and then press the Delete key. You can also delete multiple rows at once by selecting the rows and then pressing the Delete key.

Queries

Queries are used to retrieve data from a database. You can create a query by opening the Query Editor window. The Query Editor window is located in the right-hand pane of the Visual Studio window. To open the Query Editor window, click the Query Editor button on the toolbar, or press Ctrl+Q.

In the Query Editor window, enter the SQL statement that you want to use to retrieve data. For example, the following SQL statement will retrieve all of the data from the Customers table:```sql
SELECT * FROM Customers;
```

Click the Execute button on the toolbar to execute the query. The results of the query will be displayed in a grid.

Stored Procedures

Stored procedures are a type of database object that can be used to perform complex operations on data. Stored procedures are created using SQL statements. To create a stored procedure, open the Query Editor window and enter the following SQL statement:```sql
CREATE PROCEDURE GetCustomers
AS
BEGIN
SELECT * FROM Customers;
END;
```

Click the Execute button on the toolbar to create the stored procedure. You can now call the stored procedure by using the following SQL statement:```sql
EXEC GetCustomers;
```

The results of the stored procedure will be displayed in a grid.

Conclusion
