PowerServer uses the .NET Core data provider to connect with the database. The corresponding database drivers will be automatically downloaded from NuGet (www.nuget.org). All you need to do is to agree to the driver license terms in the PowerBuilder IDE.
When you create the database cache in the Database Configuration dialog box, click the View License Terms link to view the license first and then select the option "I have read and agree to the license ..." in the Database driver group. You will need to select the option for every supported database type.
The driver will be automatically downloaded to the PowerServer C# solution when the solution is opened.
For DB2, Informix, MySQL, and Oracle database, their corresponding drivers must also be downloaded to the PowerBuilder IDE as well. You will be prompted for such download (detailed instructions are provided in the subsequent sections).
For SQL Anywhere and Adaptive Server Enterprise databases that PowerServer connects with through the ODBC data source, besides the .NET Core driver, you will also need to install the ODBC driver and create the ODBC data source first in the server hosting PowerServer (detailed instructions are provided in the subsequent sections).
