Question

I’ve got a query that’s rather inefficient, and I think that I can use SQL JOIN to cut it down.

Here are the two queries:

$data = $db->query("SELECT * from tbl_forums_threads WHERE tid = '$id'");
$threaddata = $data->fetch_assoc();
$dataset = $db->query("SELECT * from tbl_forums_posts WHERE tid = '$id'");
$thread = $dataset->fetch_assoc();

Obviously, they have 1 thing in common: the use of $id.

Could I use SQL JOIN, or even LEFT JOIN?

Thanks!

Answer 1

1 SQL query with a JOIN isn’t necessarily faster than a 2 simple query like that.

Stay with this imo.
