Migrating 32-bit Applications to 64-bit
PowerBuilder IDE Limitations

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. The client database driver only needs to match the bitness of your application and does not need to match the bitness of the database server itself. In other words, a 64-bit driver can connect to a 32-bit database server and vice versa.

The following is a short list of the 3 most popular database drivers you can directly download. For other database drivers, please refer to your database vendor’s website.
