Question

This question is probably easy to solve, but here it comes.

I would like to get the latest data from each vendor (the latest row inserted into the database for each vendor).

This is some sample data from MySQL:

id  vendorId  vendor   url          delay   price0   price1   price2   price3   price4   price5   price6     date
1   1         vendor1  vendor1.com    0       12       15       18       14       25       28       25       2012-01-18 09:43:40
2   2         vendor2  vendor2.com    0       12       15       18       14       25       28       25       2012-01-18 09:43:40
3   1         vendor1  vendor1.com    0       15       17       122      12       30       52       53       2012-01-18 10:02:40
4   2         vendor2  vendor2.com    0       13       12       123      16       54       61       91       2012-01-18 10:02:40

I would like the output to be:

id  vendorId  vendor   url          delay   price0   price1    price2   price3   price4   price5   price6     date
3   1         vendor1  vendor1.com    0       15       17       122       12       30       52       53       2012-01-18 10:02:40
4   2         vendor2  vendor2.com    0       13       12       123       16       54       61       91       2012-01-18 10:02:40

What would the SQL be and how would I put the values into this array?

$vendor = array(
       array('vendorId' => '1', 'vendor' => 'vendor1', 'url' => 'vendor1', 'delay' => 0, 'price0' => 12, 'price1' => 15, 'price2' => 26, 'price3' => 14, 'price4' => 25, 'price5' => 64, 'price6' => 512),
       array('vendorId' => '2', 'vendor' => 'vendor2', 'url' => 'vendor2', 'delay' => 0, 'price0' => 12, 'price1' => 15, 'price2' => 26, 'price3' => 14, 'price4' => 25, 'price5' => 64, 'price6' => 512)
);

Thanks in advance

Also, I forgot to mention: There will be more than just 2 vendors in the database, so I’d prefer that they’d be picked up per auto.

Answer 1

SELECT max( id ) AS max_id, vendorId, url, delay, 
price0, price1, price2, price3, price4, price5, price6, date 
FROM `vendors` 
GROUP BY vendorId

You updated your question with how you should obtain the resultset into an array.
Refer here: http://php.net/manual/en/function.mysql-fetch-array.php

$row = mysql_fetch_array($result);

You will then be able to add each row as an associative array to another array containing all your vendors, accessible by key/value.
