Hi
As I'm new to PHP/MySQL
I need a little help concerning joining 4 tables in SQL query.
I have 4 tables
first is asort with 4+ columns
id catid pid tipid ...
id is primary key and catid, pid and tipid are foreign keys from tables kategorija, proizvod and tip
I want to make a query to join this 4 tables and find for example all rows with pid=4
I tryed with
$q1 = "SELECT * FROM asort LEFT JOIN (kategorija, proizvod, tip)
ON (kategorija.catid=asort.catid AND proizvod.pid=asort.pid AND tip.tipid=asort.tipid)
where tipid='$_GET[tipid]' order by cijena asc";
but I got
"Column 'tipid' in where clause is ambiguous"
Thank you for reading this especially if you are able to help me out on this.
Bye
