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. 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);
