Sorting After the Query
I have a database of catering orders. Some of the orders have refill times (1 & 2). I need to display a list of all order, including separate entries for those with refill times, in chronological order for a particular date. So if order A has 2 refill times I want to see this:
order A (9 am)
order B (10 am)
order C (11 am)
order A refill 1 (12 pm)
order D (1 pm)
order E (2 pm)
order A refill 2 (3 pm)
I am unable to figure out the query this is what I have:
This just shows the order once not 3 times (1 - for the order, 2 - for refill 1, 3 - for refill 2)
$sql1="SELECT * FROM forms_hostess WHERE month='$m' AND day='$d' AND year='$y' AND cancelled!='x' ORDER BY starttime";
I am assuming that I have to have code after the fact checking for if there are refill times and reiterated the entry but I am unsure how.
Sounds like you have built your db incorrectly. Normalize it.
I know - you don't have a clue what normalize means. It means you don't duplicate column/field data within a record - you create a second(or third or fourth, etc.) record, or you place those items that are duplicated for a key value into a second table. So - perhaps an order for a client creates and 'order' record, but if that order needs to generate multiple actions (refills), then you create the order record with the client info (perhaps) but then you create a 'order_process' table that links to the order number but then provides the refill data for that order, which will contain at least ONE record for each order.
Without a better DB schema, this is all I can think of off the top of my head:
$sql1 = <<<EOD
SELECT *, starttime AS sort_time
WHERE month='$m' AND day='$d' AND year='$y' AND cancelled!='x'
) UNION (
SELECT *, refill_1 AS sort_time
WHERE month='$m' AND day='$d' AND year='$y' AND cancelled!='x' AND refill_1 IS NOT NULL
) UNION (
SELECT *, refill_2 AS sort_time
WHERE month='$m' AND day='$d' AND year='$y' AND cancelled!='x' AND refill_2 IS NOT NULL
ORDER BY sort_time
