Connect to MySQL Data from PowerBuilder

This article demonstrates how to access MySQL data from PowerBuilder using the CData ODBC Driver for MySQL.

The CData JDBC Driver for MySQL is a standards-based control that can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to use the CData JDBC Driver for MySQL in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for MySQL to perform CRUD operations (create, read, update, and delete).

Connect to MySQL Data from PowerBuilder

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. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

  1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

    Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

  2. Click Tools -> Database Painter.
  3. Right-click the JDBC node and click New Profile.
  4. In the Database Profile Setup dialog, enter the following:
    • Profile Name: Enter a user-friendly name for the profile.
    • Driver Name: Enter the class name of the driver, cdata.jdbc.mysql.MySQLDriver
    • URL: Enter the JDBC URL. For example: jdbc:mysql: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.

  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 JDBC 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 = "JDBC" SQLCA.AutoCommit = False SQLCA.DBParm = "Driver='cdata.jdbc.mysql.MySQLDriver',URL='jdbc:mysql:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;"; CONNECT USING SQLCA; dw_orders.SetTransObject(SQLCA); dw_orders.Retrieve();
