[PHP-DB] Querying two tables
Hi all, I have several tables from which I have to fetch certain products categories based on customer selection. The tables are as follows: Table 1 - Categories catid (autonum) catname Table 2 - Sub categories subcatid (autonum) subcatname Table 3 - Products prodid (autonum) prodname Table 4 - Relationships Catid Subcatid Prodid Now, the question is how to fetch all the sub-categories let's say that are related to category 0001. I know it's as simple as relating two tables in one query, but I don't remember how. Any help appreciated. Cesar L.

[PHP-DB] SUM(colname)
Hi all, I'm trying to add all the values from the same column in MySQL with a query like this: SELECT SUM(colname) WHERE value = 'value' But then I can't output it on the screen correctly. I've tried to put all the results into an array and then make an array_sum($arrayname) and it gives me exactly the double of what it should... any suggestions? By the way, the column I'm trying to add is a DOUBLE 6,2. Thanks in advance, Cesar L.

[PHP-DB] Count AND sum columns values
Hi all, I have this table which stores products and quantities ordered by customers, and for billing purposes, I need to fetch not only how many products but also how many where ordered for each one but not detailed, but as one big result, so later I can charge for individual gift packages and stuff... How can I do this in a simple way? Thanks in advance, Cesar L.
