Issue

regression from pyodbc: 4.0.35 to 4.0.39

on 4.0.39 fetching a row from a table fails, if the field type is decimal on 4.0.35 it works just fine

Pseudocode:

    cursor.execute("select testfield_ from testtable where Nr = ?", ['42'])
    cursor.fetchone()
    Traceback (most recent call last):
    TypeError: sub() missing 1 required positional argument: 'string'
