change SQL query from PHP - php

Question

How do I change a certain SQL query form inside PHP code Like for example here in the below code
<?php
function eb_mine_views_query_alter(&$view, &$query) {
if ($view->name == 'statuser') {
dsm($query, 'before');
$query->where[0]['type'] = 'OR';
dsm($query, 'after');
}
}
?>
this code is related to a Drupal modification.
previous query
SELECT node.title AS node_title, node.nid AS nid, node.created AS node_created
FROM
{node} node
INNER JOIN {taxonomy_index} taxonomy_index_value_0 ON node.nid = taxonomy_index_value_0.nid AND taxonomy_index_value_0.tid = :views_join_condition_0
INNER JOIN {taxonomy_index} taxonomy_index_value_1 ON node.nid = taxonomy_index_value_1.nid AND taxonomy_index_value_1.tid = :views_join_condition_1
WHERE ((( (taxonomy_index_value_0.tid = :db_condition_placeholder_2) )**AND**( (taxonomy_index_value_1.tid = :db_condition_placeholder_3) )))
ORDER BY node_created DESC
After the above code runs the resulting query
SELECT node.title AS node_title, node.nid AS nid, node.created AS node_created FROM node node OUTER JOIN taxonomy_index taxonomy_index_value_0 ON node.nid = taxonomy_index_value_0.nid AND taxonomy_index_value_0.tid = '9' OUTER JOIN taxonomy_index taxonomy_index_value_1 ON node.nid = taxonomy_index_value_1.nid AND taxonomy_index_value_1.tid = '6' WHERE ((( (taxonomy_index_value_0.tid = '9') )OR( (taxonomy_index_value_1.tid = '6') ))) ORDER BY node_created DESC LIMIT 5 OFFSET 0;
As you can see the query changed from AND to OR.
Now I want to change the same code like this:
SELECT node.title AS node_title, node.nid AS nid, node.created AS node_created FROM node node LEFT OUTER JOIN taxonomy_index taxonomy_index_value_0 ON node.nid = taxonomy_index_value_0.nid AND taxonomy_index_value_0.tid = '9' LEFT OUTER JOIN taxonomy_index taxonomy_index_value_1 ON node.nid = taxonomy_index_value_1.nid AND taxonomy_index_value_1.tid = '6' WHERE ((( (taxonomy_index_value_0.tid = '9') )OR( (taxonomy_index_value_1.tid = '6') ))) ORDER BY node_created DESC LIMIT 5 OFFSET 0;
rather than using OUTER JOIN I want to use LEFT OUTER JOIN. So how do I do this in my PHP code

Try this:
<?php
function eb_mine_views_query_alter(&$view, &$query) {
if ($view->name == 'statuser') {
dsm($query, 'before');
$query->where[0]['type'] = 'OR';
$query->tables[1]['type'] = 'LEFT OUTER';
dsm($query, 'after');
}
}
?>
