This article demonstrates how to access Neo4J data from Appeon PowerBuilder using the CData ADO.NET Provider for Neo4J.
This article demonstrates using the CData ADO.NET Provider for Neo4J 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 Neo4J to retrieve data.
- In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:
Server=localhost;Port=7474;User=my_user;Password=my_password;
To connect to Neo4j, set the following connection properties:
- Server: The server hosting the Neo4j instance.
- Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
- User: The username of the user using the Neo4j instance.
- Password: The password of the user using the Neo4j instance.
- 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=CategoryId}" Header="CategoryId" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
- Add a reference to the CData ADO.NET Provider for Neo4J 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.Neo4j.Neo4jConnection conn
conn = create System.Data.CData.Neo4j.Neo4jConnection(connectionString)
System.Data.CData.Neo4j.Neo4jCommand comm
comm = create System.Data.CData.Neo4j.Neo4jCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.Neo4j.Neo4jDataAdapter dataAdapter
dataAdapter = create System.Data.CData.Neo4j.Neo4jDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
