It is possible to generate tables only - without triggers, however, it is not possible to generate triggers without tables. This relates to all items that are within or “under” entities.
Unfortunately, there is no workaround or temporary solution for this. We will deal with this issue - it’s already been requested in CR # 46 975.
I missed the most important point - write how to generate only the tables… Sorry.
So, simply select only the Entities checkbox in the Script Generation dialog | What to Generate tab. See the sub-items of the Entity and feel free to clear them.
