About

  • Status: not useful at this point; filtering after this stage doesn't speed things up. The filtering has to be done before the grouping takes place. This query can probably be discarded.
  • Requires:
  1. REDIRECT Template:l/vc/query
  • Returns: sum of "done" quantities for all packages which have been checked in each order
    • In other words, you get one record for each item in an order; that record gives the sum of quantities "done" for that item across all "checked" packages. This lets you know how many of each item remain open (to be filled).
    • This was intended to then be filtered by ID_Order, so it wouldn't be pulling in a lot of data it doesn't need, but apparently MySQL isn't clever enough to figure that out; it still takes 30-40 seconds even when filtering for just one order.
    • There is also PHP code somewhere which does this, but I needed to be able to pull these numbers up in w3tpl.
