Possibly you should let the database know about the first query. Now
it's just a very short-lived string in the Python program.

Is there no exception?

My inclination would be to go to the Python interpreter and try very
simple interactions with the database. Create a table with only one
column. Insert one value. See if the value is there. Hello, world.
