SQL JOIN
I have 2 tables that look like this
table_prodsize
prodsizeid | prodize
-------------- -------------
16 X-small
17 Small
18 Medium
19 Large
table_sizes
productid | sizeid
------------ ---------
1 17
1 18
1 19
I am trying to get records to show that DON'T match. So basically X-small should show as it is the only one not in the table_sizes table but my query is not doing that. Pleas help!
SELECT *
FROM sizes INNER JOIN prodsize ON sizes.sizeid != prodsize.prodsizeid
WHERE productid = colname
colname:
$colname_rs_sizes = "-1";
if (isset($_GET['ProductID'])
$colname_rs_sizes = $_GET['ProductID'];
}

Okay, you muddled the order around a bit so I tried it with the order I want and it worked like a charm! Great stuff, thanks so much! Points on the way..
SELECT *
FROM prodsize
WHERE prodsizeid not in (SELECT sizeid FROM sizes INNER JOIN prodsize ON sizes.sizeid = prodsize.prodsizeid WHERE productid = colname)
SELECT *
FROM prodsize
WHERE prodsizeid not in (SELECT sizeid FROM sizes INNER JOIN prodsize ON sizes.sizeid = prodsize.prodsizeid WHERE productid = colname)
