Important

The appropriate data provider must be installed on the client machine. For information on data providers, refer to the Data Sources article.

Create a Data Source in the Data Source Wizard

To connect to a Teradata database in the Dashboard Designer, follow the steps below:

Click the New Data Source button in the Data Source ribbon tab.
On the first page of the invoked Data Source Wizard dialog, specify whether you want to use an existing data connection or create a new data connection.
On the next page, select Teradata and click Next.
On the next page, specify connection parameters.
Click Next and specify how to select data from the database.
On the final page, you can optionally add query parameters and preview data.

Create a Data Source in Code

To create a data source that uses a connection to the Teradata database, create an instance of the DashboardSqlDataSource class and follow the steps below:

Specify connection parameters for the Teradata database. Create the TeradataConnectionParameters class object and specify the following properties:
Create one of the following objects to specify the query:
Add the created DashboardSqlDataSource object to the Dashboard.DataSources collection.

The following code snippet shows how to supply the dashboard with data from the Teradata Northwind database:

C#
VB.NET

csharp

using DevExpress.DashboardCommon;
using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
// ...
            TeradataConnectionParameters teradataParams = new TeradataConnectionParameters();
            teradataParams.ServerName = "localhost";
            teradataParams.PortNumber = 1025;
            teradataParams.DatabaseName = "Northwind";
            teradataParams.UserName = "Admin";
            teradataParams.Password = "password";

            DashboardSqlDataSource sqlDataSource = new DashboardSqlDataSource("Data Source 1", teradataParams);
            SelectQuery selectQuery = SelectQueryFluentBuilder
                .AddTable("SalesPerson")
                .SelectColumns("CategoryName", "Extended Price")
                .Build("Query 1");
            sqlDataSource.Queries.Add(selectQuery);
            sqlDataSource.Fill();
            dashboard.DataSources.Add(sqlDataSource);

Imports DevExpress.DashboardCommon
Imports DevExpress.DataAccess.ConnectionParameters
Imports DevExpress.DataAccess.Sql
' ...
            Dim teradataParams As New TeradataConnectionParameters()
            teradataParams.ServerName = "localhost"
            teradataParams.PortNumber = 1025
            teradataParams.DatabaseName = "Northwind"
            teradataParams.UserName = "Admin"
            teradataParams.Password = "password"

            Dim sqlDataSource As New DashboardSqlDataSource("Data Source 1", teradataParams)
            Dim query As SelectQuery = SelectQueryFluentBuilder _ 
                .AddTable("SalesPerson") _ 
                .SelectColumns("CategoryName", "Extended Price") _
                .Build("Query 1")
            sqlDataSource.Queries.Add(selectQuery)
            sqlDataSource.Fill()
            dashboard.DataSources.Add(sqlDataSource)
