Connect to ServiceNow Data from PowerBuilder
This article demonstrates how to access ServiceNow data from Appeon PowerBuilder using the CData ADO.NET Provider for ServiceNow.
This article demonstrates using the CData ADO.NET Provider for ServiceNow 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 ServiceNow to retrieve data.
About ServiceNow Data Integration
CData simplifies access and integration of live ServiceNow data. Our customers leverage CData connectivity to:
- Get optimized performance since CData uses the REST API for data and the SOAP API for schema.
- Read, write, update, and delete ServiceNow objects like Schedules, Timelines, Questions, Syslogs and more.
- Use SQL stored procedures for actions like adding items to a cart, submitting orders, and downloading attachments.
- Securely authenticate with ServiceNow, including basic (username and password), OKTA, ADFS, OneLogin, and PingFederate authentication schemes.
Many users access live ServiceNow data from preferred analytics tools like Tableau, Power BI, and Excel, and use CData solutions to integrate ServiceNow data with their database or data warehouse.
Getting Started
- In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:
OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Username=MyUsername;Password=MyPassword;Instance=MyInstance;InitiateOAuth=GETANDREFRESH
ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.
See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.
- 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=sys_id}" Header="sys_id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=sys_id}" Header="sys_id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid> - Add a reference to the CData ADO.NET Provider for ServiceNow 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.ServiceNow.ServiceNowConnection conn
conn = create System.Data.CData.ServiceNow.ServiceNowConnection(connectionString)
System.Data.CData.ServiceNow.ServiceNowCommand comm
comm = create System.Data.CData.ServiceNow.ServiceNowCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.ServiceNow.ServiceNowDataAdapter dataAdapter
dataAdapter = create System.Data.CData.ServiceNow.ServiceNowDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
