Connect to MySQL Data from PowerBuilder

This article demonstrates how to use the CData ODBC Driver for MySQL to connect to MySQL data and execute queries in PowerBuilder.

The CData ODBC Driver for MySQL can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to connect to MySQL data and execute queries from the Database Painter and controls such as the DataWindow.

Create a Profile for the ODBC Driver for MySQL

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for MySQL. In the Database Painter, you can use wizards and the UI to work with MySQL data.

  1. If you have not already done so, create an ODBC DSN for MySQL. The DSN contains the connection properties required to connect to MySQL data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:
    • User
    • Password
    • Database
    • Server
    • Port

    Server およびPort プロパティがMySQL への接続には必須です。IntegratedSecurity をFALSE に設定した場合、User、Password も必須になります。 オプションで、Database を設定することもできます。Database は設定がない場合すべてのデータベースを使えるようになります。

    See the help documentation for a guide to creating a MySQL DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the MySQL DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using MySQL Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve MySQL data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData MySQL Source'" CONNECT USING SQLCA; dw_orders.SetTransObject(SQLCA); dw_orders.Retrieve();
