How to execute my SQL query in CodeIgniter

Question

I have a problem with my query and I need to join two tables from different databases now my problem is how can I execute my query. I got my syntax format f

Answer 1

If the databases share server, have a login that has priveleges to both of the databases, and simply have a query run similiar to:

$query = $this->db->query("
SELECT t1.*, t2.id
FROM `database1`.`table1` AS t1, `database2`.`table2` AS t2
");

Otherwise I think you might have to run the 2 queries separately and fix the logic afterwards.
