Install 64-bit database drivers to your development machine. As already mentioned in this guide, a 64-bit database driver is required for you to debug or run the 64-bit version of your application in the PowerBuilder, or run the compiled 64-bit version.
In addition, make the necessary changes to your database connection as applicable.

For ODBC connections:
If you are using ODBC drivers to connect to your database, then you need to create the ODBC data source for your 64-bit driver. Follow the instructions here.
If your new ODBC data source requires any special settings, like specific database parameters, apply those changes to the newly created data source. For a complete list of database parameters read the Database parameters and supported database interfaces online document.
