Thanks for taking the time to respond.
What am I trying to do?
Well...I am trying to build a mailing list of previous customers WHO
purchased product_id 1 but not product_id 14.
I have the product items (id's) stored in the CartTable and I have
customer info stored in the OrderTable.
Using the same column of cart_id in both CartTable and OrderTable I am
able to reference which cart items (id's) belong to each record in the
What I did originally (that didn't work) was to select all records in
the CartTable that matched product_id=1 and product_id!=14 then I used
that information to reference against the OrderTable to grab the
customer information I needed.
The problem with my logic is that I did not take into account those who
purchased one of the product_id's on ONE purchase and then came back the
next day, week, year, etc and made another purchase for the other
I NEED to make sure that a customer HAS purchased product_id=1 and NOT
product_id=14 at ANY time, regardless of a single or multiple orders.
Does this make any sense? *sigh*
