I noticed if you use the cursor.fetchmany it returns the pyodbc types. Is
this an issue with the dialect? if you use the connection execute you are
correct it returns a resultrow. Thanks for the help.
cursor = connection.cursor()
cursor.execute("SELECT * FROM mytable")
results_one = cursor.fetchmany(100)
for row in results_one:
print(type(row))
