# Query
|
|
|
|
A query builder/abstraction layer.
|
|
|
|
## Requirements
|
|
* 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
|
|
|
|
* 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); |
