q: "How do I create a enterprise geodatabase if my license is ArcGIS For Workgroup? "
ArcGIS Enterprise Workgroup allows you to create databases in SQL Express. Oracle isn't an option with that license.

ARCGIS ENTERPRISE WORKGROUP LEVEL ArcGIS Enterprise Workgroup is a lower capacity level of ArcGIS Enterprise.
It offers all the same functionality as ArcGIS Enterprise but is designed for use in smaller teams and organizations.
The Workgroup level has the following differences:
• There is a limit of 10 simultaneous desktop connections to workgroup geodatabases.
Workgroup geodatabases are only supported on Microsoft SQL Server Express and have a maximum size of 10 GB.
• The Workgroup level is only licensed for use with file-based data sources (e.g. file geodatabases) and workgroup geodatabases. It is not licensed for use with enterprise geodatabases.
• The base ArcGIS Enterprise deployment must be deployed all-in-one on a single machine with up to 4 cores.
• Each server role has a 4-core maximum. The additional roles can be deployed on separate machines from the base deployment. The spatiotemporal big data store from ArcGIS Data Store may be configured on a single, separate 4-core machine.
