Connect to Redis Data from PowerBuilder

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

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 Redis in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Redis 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=127.0.0.1;Port=6379;Password=myPassword;

    Set the following connection properties to connect to a Redis instance:

    • Server: Set this to the name or address of the server your Redis instance is running on. You can specify the port in Port.
    • Password: Set this to the password used to authenticate with a password-protected Redis instance , using the Redis AUTH command.

    Set UseSSL to negotiate SSL/TLS encryption when you connect.

  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=City}" Header="City" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Redis 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.Redis.RedisConnection conn conn = create System.Data.CData.Redis.RedisConnection(connectionString) System.Data.CData.Redis.RedisCommand comm comm = create System.Data.CData.Redis.RedisCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Redis.RedisDataAdapter dataAdapter dataAdapter = create System.Data.CData.Redis.RedisDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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