Multi Query
출처: http://php.net/manual/en/function.mysql-query.php
You can put multiple query with PHP && MySQL:
//initialise MySQL users variables
mysql_query("select @a:=0,@b:=0");
//select values of variables
mysql_query("select @a:=sum(rate), @b:=count(*) from ratetable where rated_user_id='$id'");
//finally, select for result
$rate_id_select=mysql_query("select @c:=round(@a/@b) as effective_rate");
//..and result $rate_user=mysql_result($rate_id_select,0,"effective_rate");
...
echo $rate_user;
