If your application needs to access external databases through ODBC, you can create the necessary ODBC connection in Plesk. After you have created the ODBC connection, you can customize the application to use that ODBC connection to access information in the database.
Note that the database does not necessarily need to be external; ODBC can be used to access local databases as well.
To create a new ODBC connection to a database:
1. Go to **Websites & Domains** and click **ODBC Data Sources**.
2. Click **Add ODBC DSN**.
3. Specify the ODBC connection name and description in the corresponding fields.
4. Select the required driver in the **Driver** field.
5. Click **Create ODBC DSN**.
6. Choose the appropriate options on the driver configuration screen. Typically, you should specify the path to the database, user credentials and other connection options, depending on the selected driver.
7. Click **Test connection** to check whether the connection will function properly with provided settings. Click **Save** to complete the creation.
To change settings of an existing ODBC connection:
1. Go to **Websites & Domains** and click **ODBC Data Sources**.
2. Click the required connection name in the list.
3. Change the settings as needed.
4. Click **Test connection** to check whether the connection will function properly with new settings. Click **Save** to save changes.
To remove an ODBC connection:
1. Go to **Websites & Domains** and click **ODBC Data Sources**.
2. Select the checkbox next to the connection you want to remove.
3. Click **Remove**, and then click **Yes, remove**.
