Connect to MySQL Data from PowerBuilder via JDBC

The CData JDBC driver for MySQL is a standards-based control that can be used from any platform or development technology that supports JDBC, including 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 reads and writes.

Connect to MySQL Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL 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.

     The CData Provider supports connecting to on-premises and cloud-hosted versions of MySQL such as Amazon RDS for MySQL, Google Cloud SQL for MySQL, Azure Database for MySQL, or Oracle MySQL HeatWave. 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.

     SSH Connectivity for MySQL

     You can use SSH (Secure Shell) to authenticate with MySQL, whether the instance is hosted on-premises or in supported cloud environments. SSH authentication ensures that access is encrypted (as compared to direct network connections).

     SSH Connections to MySQL in Password Auth Mode

     To connect to MySQL via SSH in Password Auth mode, set the following connection properties:

     • User: MySQL User name
     • Password: MySQL Password
     • Database: MySQL database name
     • Server: MySQL Server name
     • Port: MySQL port number like 3306
     • UserSSH: "true"
     • SSHAuthMode: "Password"
     • SSHPort: SSH Port number
     • SSHServer: SSH Server name
     • SSHUser: SSH User name
     • SSHPassword: SSH Password

     SSH Connections to MySQL in Public Key Auth Mode

     To connect to MySQL via SSH in Password Auth mode, set the following connection properties:

     • User: MySQL User name
     • Password: MySQL Password
     • Database: MySQL database name
     • Server: MySQL Server name
     • Port: MySQL port number like 3306
     • UserSSH: "true"
     • SSHAuthMode: "Public_Key"
     • SSHPort: SSH Port number
     • SSHServer: SSH Server name
     • SSHUser: SSH User name
     • SSHClientCret: the path for the public key certificate file

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the MySQL JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.mysql.jar
     

     Fill in the connection properties and copy the connection string to the clipboard. A typical JDBC URL is below:

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

   👁 The JDBC data source defined in the Database Profile Setup dialog. (Salesforce is shown.)
   
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();
