Connect to IBM Cloud Data Engine Data from PowerBuilder
This article demonstrates how to access IBM Cloud Data Engine data from Appeon PowerBuilder using the CData ADO.NET Provider for IBM Cloud Data Engine.
This article demonstrates using the CData ADO.NET Provider for IBM Cloud Data Engine in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.
This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for IBM Cloud Data Engine to perform reads and writes.
- In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:
Api Key=MyAPIKey;Instance CRN=myInstanceCRN;Region=myRegion;Schema=mySchema;OAuth Client Id=myOAuthClientId;OAuth Client Secret=myOAuthClientSecret;InitiateOAuth=GETANDREFRESH
IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.
- Add the DataGrid control from the .NET controls.
-
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> - Add a reference to the CData ADO.NET Provider for IBM Cloud Data Engine 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.IBMCloudDataEngine.IBMCloudDataEngineConnection conn
conn = create System.Data.CData.IBMCloudDataEngine.IBMCloudDataEngineConnection(connectionString)
System.Data.CData.IBMCloudDataEngine.IBMCloudDataEngineCommand comm
comm = create System.Data.CData.IBMCloudDataEngine.IBMCloudDataEngineCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.IBMCloudDataEngine.IBMCloudDataEngineDataAdapter dataAdapter
dataAdapter = create System.Data.CData.IBMCloudDataEngine.IBMCloudDataEngineDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
