# Query
A query builder/abstraction layer.
## Requirements
2012-03-15 12:09:43 -04:00
* Pdo extensions for the databases you wish to use (unless it's Firebird, in which case, the interbase extension is required)
* PHP 5.2+
## Databases Supported
2012-03-15 12:09:43 -04:00
* Firebird
* MySQL
* PostgreSQL
* SQLite
* Others, via ODBC
## Connecting
Create a connection array or object similar to this:
<?php
$params = array(
'type' => 'mysql',
'host' => 'localhost',
'user' => 'root',
'pass' => '',
'port' => '3306',
'database' => 'test_db',
// Only required
// SQLite or Firebird
'file' => '/path/to/db/file',
);
$db = new Query_Builder($params);
The parameters required depend on the database.
### Running Queries
Query uses the same interface as CodeIgniter's [Active Record class](http://codeigniter.com/user_guide/database/active_record.html). However, it does not implement the `select_` methods, `count_all_results`, or `count_all`.
To retreive the results of a query, use the PDO methods `fetch` and `fetchAll`.

$query = $db->get('table_name');
$results = $query->fetchAll(PDO::FETCH_ASSOC);
