ModuleNotFoundError Traceback (most recent call last)
Cell In[2], line 1
----> 1 from sqlalchemy.databases.mysql import MSTinyInteger
ModuleNotFoundError: No module named 'sqlalchemy.databases.mysql'
In [3]: from sqlalchemy.databases import mysql
In [4]: mysql.MSTinyInteger
Out[4]: sqlalchemy.dialects.mysql.types.TINYINT

We need to import mysql.MSTinyInteger, not MSTinyInteger directly

IMO, Correct import would be from sqlalchemy.dialects.mysql.base import MSTinyInteger

* Use str type for driver and name in HiveDialect (dropbox#450)
PyHive's HiveDialect usage of bytes for the name and driver fields is not the norm is causing issues upstream: apache/superset#22316
Even other dialects within PyHive use strings. SQLAlchemy does not strictly require a string, but all the stock dialects return a string, so I figure it is heavily implied.
I think the risk of breaking something upstream with this change is low (but it is there ofc). I figure in most cases we just make someone's `str(dialect.driver)` expression redundant.
Examples for some of the other stock sqlalchemy dialects (name and driver fields using str):
