SingleStore ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with SingleStore.



Use the CData ADO.NET Provider for SingleStore with the DevExpress Windows Forms and Web controls to provide SingleStore data to a chart.

The CData ADO.NET Provider for SingleStore implements standard ADO.NET data access components that can be used with third-party controls. The standard ADO.NET process for databinding can be followed to enable bidirectional access to live data from UI controls. In this article we show how to use the CData components to databind to the DevExpress Windows Forms and Web controls; you will databind to a chart that displays current data.

The following connection properties are required in order to connect to data.

  • Server: The host name or IP of the server hosting the SingleStore database.
  • Port: The port of the server hosting the SingleStore database.
  • Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

  • User: The user which will be used to authenticate with the SingleStore server.
  • Password: The password which will be used to authenticate with the SingleStore server.

Connect Using Integrated Security

As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:

  • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
  • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
  • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
  • SSLClientCertType: The certificate type of the client store.
  • SSLServerCert: The certificate to be accepted from the server.

Connect Using SSH Authentication

Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

  • SSHClientCert: Set this to the name of the certificate store for the client certificate.
  • SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
  • SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
  • SSHClientCertType: The certificate type of the client store.
  • SSHPassword: The password that you use to authenticate with the SSH server.
  • SSHPort: The port used for SSH operations.
  • SSHServer: The SSH authentication server you are trying to authenticate against.
  • SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
  • SSHUser: Set this to the username that you use to authenticate with the SSH server.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with SingleStore data. The SingleStoreDataAdapter binds to the Series property of the chart control. The Diagram property of the control defines the x- and y-axes as the column names.

using (SingleStoreConnection connection = new SingleStoreConnection( "User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;")) { SingleStoreDataAdapter dataAdapter = new SingleStoreDataAdapter( "SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'", connection); DataTable table = new DataTable(); dataAdapter.Fill(table); DevExpress.XtraCharts.Series series = new DevExpress.XtraCharts.Series(); chartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "ShipCity" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "ShipName"; series.ValueScaleType = DevExpress.XtraCharts.ScaleType.Numerical; chartControl1.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }

Web Controls

The code below shows how to populate a DevExpress Web control with SingleStore data. The SingleStoreDataAdapter binds to the Series property of the chart; the Diagram property defines the x- and y-axes as the column names.

using DevExpress.XtraCharts; using (SingleStoreConnection connection = new SingleStoreConnection( "User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;")) { SingleStoreDataAdapter SingleStoreDataAdapter1 = new SingleStoreDataAdapter("SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'", connection); DataTable table = new DataTable(); SingleStoreDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "ShipCity" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "ShipName"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
