I'd be most comfortable with this approach. I'd worry about adding a PDO::PARAM_NUMERIC type without investigating how it needs to function for each DB, which feels like scope creep. If it starts off as an alias for PDO::PARAM_STR, there could be issues updating it to work correctly, especially if the right design involves modeling the precision somewhere. I added a "Future Scope" section covering this. Let me know if there are major problems with this or other points to cover. Otherwise, I'll aim to open voting on Monday. Thanks, Adam
