Hi, thanks for reaching out.
I can't seem to be able to replicate the described behavior right away, i.e. I was able to do
print(qc.mydb_list())
and then
qc.mydb_drop('foobtable')
A subsequent print(qc.mydb_list()) did not show 'footable' anymore.
Can you please let us know the exact table names in your MyDB that are still showing after you tried to drop them?
Thanks,
Robert
