[SOLVED] INNER JOIN - does the order of the ON elements matter ?

[scanreg]

I have the following:

 

	$categoryid =  mysqli_real_escape_string($link,	$_GET['category']);
if ($categoryid != '') // A category is selected
{
	$from  .= ' INNER JOIN jokecategory ON id = jokeid';
	$where .= " AND categoryid='$categoryid'";
}

 

Does the order of the "ON id = jokeid';" matter? For instance, would the following be just as valid:

 

$from  .= ' INNER JOIN jokecategory ON jokeid = id';

 

An experiment seems to indicate that it doesn't but wanted to ask

 

Many thanks
