And he stating incorrect information here "because you're deciding the size of a group and when to synchronize within that group". As mentioned above you can let the runtime decide the group size.

Python 3 throws a syntax error on the first example. Here's the first 2 lines updated to work on python 3: `for key, group in groupby(enumerate(data), lambda i: i[0] - i[1]): group = list(map(itemgetter(1), group))`

@ypercubeᵀᴹ why do you say it's incorrect? This is exactly what I was looking for, and a correct interpretation of "group by multiple columns". In fact, I don't know why this isn't the behavior of "group by col1, col2" like I'd expect

I bet your join conditions are not 1:1, remove the group by to see what's going on. By the way it's recommended to use explicit join syntax, rather than pre-92 implicit syntax.

Is it giving you any error messages? Because it should. This _(SELECT products.products_id, products.product_reseller_account_no, products.product_certain_amount, products.product_stock_amount, products.product_group_number, products.products_status, products.products_competitor_watch, products.manufacturers_id FROM products GROUP BY products.products_id)_ is not correct syntax. You have a GROUP BY and lots of non-aggregate attributes that aren't in the GROUP BY in the select.
