Query

A query builder/abstraction layer, using prepared queries for security.

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

Including Query in your application

To include Query in your PHP project, just include the autoload.php file. This will automatically load the classes that are supported by the current PHP installation.

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. However, it does not implement the select_ methods, count_all_results, distinct, having, or_having, get_compiled_query, insert_batch, update_batch, or count_all methods.

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);
