How to find object dependencies

Hi,
I am dropping table, and got an error "Cannot drop Table XXX because other objects depends on it". I do not want to use "cascade" - I want to understand what will be dropped.
I seems to be cannot find system table/view that will list object dependencies.
Can you post here a query that will list object dependencies. Just one level of dependencies would be enough.
I am on v 12.0.4.
Thank you
Sergey

    Do you have any user created projections on that table? if so, could you please try dropping those projections first?

    @SruthiA
    It appears Vertica tables do not have any dependencies except projections.
    This specific table where I got dependencies error, had only 2 regular superprojections.
    Table is very old, seems to be projections were created using some old syntax. Projections looks same as any other projection, but Vertica want "cascade" in table drop.

    old syntax projection definition might have caused the problem then
