@ -81,3 +81,23 @@ To retreive the results of a query, use the PDO method [fetch](http://php.net/ma
$query = $db->get('table_name');
$results = $query->fetchAll(PDO::FETCH_ASSOC);
### Inserting / Updating
An example of an insert query:
$query = $db->set('foo', 'bar')
->set('foobar', 'baz')
->where('foo !=', 'bar')
->insert('table');
An example of an update query:
$query = $db->set('foo', 'bar')
->set('foobar', 'baz')
->where('foo !=', 'bar')
->update('table');
The `set` method can also take an array as a paramater, instead of setting individual values.
