Question

For Example I’ve got 2 databases called: Site_X and Site_Y

Site X DB – Has the table Data

Site Y DB – Has the table Data_ids

How can I use kohana to get all the data from Site X DB that has id equal to what I find in Site Y DB.

Answer 1

First define config for both DBs in config/database.php

Then you can do the following (replace site_y, site_x with config names for your databases):

$ids = Database::instance('site_y')
    ->query(Database::SELECT, 'SELECT `id` FROM `Data_ids`')
    ->execute();
$results = Database::instance('site_x')
    ->query(Database::SELECT, 'SELECT `id` FROM `Data` WHERE `id` IN ('.implode(",", $ids).')')
    ->execute();
