DSN-less connections

A DSN-less connection enables you to specify the required parameters, such as the driver name, authentication details, and server information, directly in a connection string without having to configure a DSN in the ODBC Data Source Administrator.

Create a DSN-less connection

You can create a DSN-less connection by directly specifying all the connection parameters in the string.

Example

DRIVER={Devart ODBC Driver for xBase};Database=your_database_files_location;

The connection string contains the following parameters:

• Database – The path to the xBase database files.

Test the connection

You can test the DSN-less connection by running your application or using tools such as isql or ODBC Test to verify that the connection is established successfully.

The following example uses the New-Object cmdlet to create an ODBC connection.

$ConnectionString = "DRIVER={Devart ODBC Driver for xBase};Database=your_database_files_location;"

try {
    $conn = New-Object System.Data.Odbc.OdbcConnection
    $conn.ConnectionString = $ConnectionString
    $conn.Open()
    Write-Host "Connection successful!"
    $conn.Close()
} catch {
    Write-Host "Connection failed: $_"
}

Additional parameters

Devart ODBC Driver for xBase allows configuring additional parameters to customize the connection and the driver’s behavior. For a full list of available parameters, see xBase ODBC connection string parameters.

Use a DSN-less connection in a .NET application

using System;
using System.Data.Odbc;

class Program
{
    static void Main()
    {
        string connectionString = "DRIVER={Devart ODBC Driver for xBase};Database=your_database_files_location;DBFFormat=your_database_format;CodePage=your_code_page;ConnectMode=your_access_mode;";
        
        using (OdbcConnection connection = new OdbcConnection(connectionString))
        {
            connection.Open();
            Console.WriteLine("Connected to xBase!");
            
            // Perform your queries or operations here.
        }
    }
}
