I currently use Delphi 10.4 Sidney to build my own 64-Builds. But now i am interrested in adding Oracle Database support but it seems FireDAC Oracle SQL-Drivers are NOT included in the Community Edition.
So i checked out a Trial Edition and viola, all the missing FireDAC Databases Drivers like Oracle, IBM-DB/2, Sybase ect are now listed. I can now connect (via FireDAC) to Oracle 10 upto Oracle 21c SQL-Servers (using Oracle Basic Instant Client package for Oracle 10g, it conains all required OCI DLL's). It is possible to use FBConnections, Query, Datasource and all the DBGrid and Navigator Components.
Only caviat, it's not possible with the Free Community Edition.
