Hi! I'm still having issue dropping internal tables from the MERGE TABLE. I used to have this problem on a previous version. I have created a new DB, imported all the data... and now I need to delete a partition (NOT a table). I'm still facing the same problem, which is that I cannot remove it from the merge table. (as you can see below).. Is there anything I can do?
