1) "Views" in sqlite:
sqlite does not have ALTER TABLE ... DROP COLUMN so that explains
the "extra" fields.
2) Thanks for the ipython suggestion and the SQLDB._instances
explanation.
What I find obscure is the use of SQLBD._instances by itself.
SQLDB is a class and yes, it has an attribute named _instances, so
far so good.
Defined databases are instances of SQLDB and I would understand the
use of dbA._instances but SQLDB._instances?.
3) In the meantime to find the defined databases I came up with
something like this:
DBs={}
DBtype=type(SQLDB())
for n in globals():
if type(globals()[n])==DBtype:
DBs[n]=globals()[n]
I think I needed something like this a while back...
