JAQB

JAQB: Just Another Query Builder for PHP (pronounced "jacob")

Requirements

• PHP 5.6+, PHP 7+
• PDO

Installation

The easiest way to install JAQB is with composer:

composer require jaqb/jaqb

Configuration

The connection manager accepts an array of connection configurations. With the connection manager you can conveniently manage one or more database connections. Connections are referenced by a unique ID in the configuration.

use JAQB\ConnectionManager;

$config = [
    'main' => [
        'type' => 'mysql',
        'host' => 'localhost',
        'name' => 'dbname'
        'username' => 'myuser',
        'password' => 'mypassword',
        'options' => [
            PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
        ]
    ],
    'sqlite' => [
        'dsn' => 'sqlite:mydb.sqlite'
    ]
];

$manager = new ConnectionManager($config);

Supplying an existing PDO object

You can also manually add existing PDO connections.

use JAQB\ConnectionManager;
use JAQB\QueryBuilder;

$pdo = new PDO('...');
$connection = new QueryBuilder($pdo);
$manager = new ConnectionManager();
$manager->add('users', $connection); 

Usage

Retrieving a connection

You can retrieve a connection by calling get() on the connection manager with the ID of the connection.

$db = $manager->get('main');

If there is only one connection then you can also get it as the default.

$db = $manager->getDefault();

Select Query

$db->select('*')
   ->from('Movies')
   ->join('Directors', 'Directors.id = Movies.director_id')
   ->where('Directors.name', 'Quentin Tarantino')
   ->between('year', 1990, 2015)
   ->groupBy('category')
   ->having('rating', 4.5, '>')
   ->orderBy('rating', 'DESC')
   ->limit(100, 10)
   ->all();

Insert Query

$db->insert(['name' => 'Catcher in the Rye', 'author' => 'JD Salinger'])
   ->into('Books')
   ->execute();

Update Query

$db->update('Users')
   ->where('uid', 10)
   ->values(['first_name' => 'JAQB', 'website' => 'example.com'])
   ->orderBy('uid', 'ASC')
   ->limit(100)
   ->execute();

Delete Query

$db->delete('Users')
   ->where('last_login', strtotime('-1 year'), '<')
   ->limit(100)
   ->orderBy('last_login', 'ASC')
   ->execute();

Pure SQL Query

$db->raw('SHOW COLUMNS FROM `Events`')
   ->execute();

Executing a Query

The following methods can be used to execute a query and retrieve results:

• execute() - returns a PDOStatement
• all() - returns all of the rows
• one() - returns the first row
• column($index = 0) - returns a specific column from each row
• scalar($index = 0) - returns a specific column from the first row

Also:

• rowCount() - returns the number of rows affected by the last executed statement
• $db->lastInsertId() - returns the last inserted ID

Transactions

Queries support PDO transactions.

$db->beginTransaction();

try {
    for ($i = 1; $i <= 10; $i++) {
        $db->insert(['name' => "Item # $i"])
           ->into('Items')
           ->execute();
    }
    
    $db->commit();
} catch (Exception $e) {
    $db->rollBack();
}

Building a Query

If you want to build a query without executing it just use build() instead. getValues() will retrieve any ordered question mark parameters.

Tests

Use phpunit to run the included tests:

phpunit
