php multiple databases issue

I've set two database conections as below

$con1 = mysql_connect("localhost", "root", "pwd") or die (mysql_error());

$con2 = mysql_connect("localhost", "wordpress", "pwd", true) or die(mysql_error());

mysql_select_db("lab_ancp", $con1) or die(mysql_error());   
mysql_select_db("wordpress",$con2) or die(mysql_error());

and it works fine

so then i do some queries on a page like this:

$sql="select unome from associado where uid=$uid";
    $result=mysql_query($sql,$con1) or die(mysql_error());

and it works fine, after that i do a second query like this:

$sql="select ID, post_content, post_title, post_excerpt, meta_value
                    from wp_posts join (
                        select post_id, meta_value 
                        from wp_postmeta 
                            join (
                                select post_id from wp_postmeta
                                where meta_key='destaque' and meta_value='s'
                            )as t1 using(post_id)
                        where meta_key='pft_widescreen'
                    ) as t2 on (wp_posts.ID=t2.post_id)
                ORDER BY RAND() LIMIT 1";
            //echo $sql . "<br />";
            $row=mysql_fetch_assoc(mysql_query($sql,$con2)) or die(mysql_error());

and again everything is just fine, but then....

$sql="select * from eventos where edatade>='$hoje' or edataate>='$hoje'";
            $result=mysql_query($sql, $con1) or die (mysql_error());

gives this error:

**

SELECT command denied to user 'wordpress'@'localhost' for table 'eventos'

**

Well

Its solved.

Don't askme the reason but i've tried to change the order in the first two roww, i.e put $con2 before $con1 and the queries now simply work fine.

I suspect that the ..."true" parameter has something to do with that.

Thx guys.
