   Actually, while I agree it's unintuitive, that's the behavior prescribed in the [Python DB API](https://www.python.org/dev/peps/pep-0249/) (emphasis mine):
   
   > .fetchall()
   > Fetch all (remaining) rows of a query result, returning them as a sequence of sequences (e.g. a list of tuples). Note that the cursor's arraysize attribute can affect the performance of this operation.
   > 
   > **An Error (or subclass) exception is raised if the previous call to .execute\*() did not produce any result set or no call was issued yet.**
   
   I'll test if it works without the patch.
