Description

Limit the sqlachemy version requires to sidestep pandas+sqlalchemy>2.0.0 issues with pd.read_sql(), pd.read_sql_table() and pd.read_sql_query(). See #352

Non-technical explanation

Installing trino[sqlalchemy] installs a version that breaks methods such as pd.read_sql() and pd.read_sql_table(). This will limit the sqlalchemy version to sidestep these bugs.

Hi @GitToby, we actually want to be compatible with sqlalchemy 2.0.0. What is exactly the issue that you are facing?

[GitToby]

see issue #352 - ultimately this is an issue due to the bug in pandas where pandas 1.5.x doesn't work with sqlalchemy>2.0.0 because of a change in API. The default trio[sqlalchemy] install will hence fail when calling the pandas methods that leverage sqlalchemy tools.

This is something Pandas fixed in their 2.0 release. It should be improved upstream in Pandas (or by the user by pinning a specific version) in case of incompatibilities. This client itself works with SQLA 2.x fine so no changes need to be done here.
