Question

<?php  $query = mysql_query('SELECT * FROM threads                            INNER JOIN accounts                           ON threads.author = accounts.id                            WHERE id = '.intval($_GET['threadID'])); $row = mysql_fetch_assoc($query);  $title = $row['title'];  ?> 

What if I have a column named the same in both tables? (title) How does it know which one to get? How can I tell it to get it from accounts table not threads without have different name on them.

Answer 1

You can use an alias to fetch the column with a different name

SELECT t.*, a.title AS account_title  FROM threads t INNER JOIN accounts... 

If you only want to fetch the accounts title, list the columns from threads that you DO want

SELECT t.wanted_column, t.another_column, a.*  FROM threads t, INNER JOIN accounts a...
