Connect to MySQL Data from PowerBuilder

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

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 MySQL in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for MySQL 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:

    User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;

    The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.

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

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