Review Comment:
@uranusjr This doesn't look true to me, I am using the following as
reference:
- https://peps.python.org/pep-0249/#description
-
https://docs.sqlalchemy.org/en/14/core/connections.html?highlight=returns_#sqlalchemy.engine.CursorResult.returns_rows
Also:
```python
>>> import pymssql
>>> c = pymssql.connect(host, login, password)
>>> cur = c.cursor()
>>> cur.execute("SELECT SUSER_SNAME();")
>>> cur.rowcount
-1
>>> cur.description
(('', 1, None, None, None, None, None),)
>>> cur.execute("PRINT('1');")
>>> cur.rowcount
-1
>>> cur.description
```
Edit: I have the same behaviour with `sqlite3` and `jaydebeapi`
