IBM Informix ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with IBM Informix.



This article demonstrates how to access IBM Informix data from PowerBuilder using the CData ADO.NET Provider for IBM Informix.

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for IBM Informix in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for IBM Informix to perform reads and writes.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

    Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;

    Set the following properties to connect to IBM Informix

    • Server: Set this to the name of the server running IBM Informix.
    • Port: Set this to the port the IBM Informix server is listening on.
    • Database: Set this to the name of the IBM Informix database.
    • User: Set this to the username of a user allowed to access the database.
    • Password: Set this to the password of a user allowed to access the database.

  2. Add the DataGrid control from the .NET controls.
  3. Configure the columns of the DataGrid control. Below are several columns from the Account table: <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for IBM Informix assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.Informix.InformixConnection conn conn = create System.Data.CData.Informix.InformixConnection(connectionString) System.Data.CData.Informix.InformixCommand comm comm = create System.Data.CData.Informix.InformixCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Informix.InformixDataAdapter dataAdapter dataAdapter = create System.Data.CData.Informix.InformixDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
