Query Builder for easing the SQL composing

Installing

Installing via Composer

Append the lib to your requirements key in your composer.json.

{
    // composer.json
    // [..]
    require: {
        // append this line to your requirements
        "php-objects/php-query-builder": "dev-master"
    }
}

Alternative install

• Learn composer. You should not be looking for an alternative install. It is worth the time. Trust me ;-)
• Follow this set of instructions

Usage

SELECT

This is an example of select query.

• Applies limit
• Applies where
• Applies orderBy
• Applies groupBy
• Applies placeholders

$fields = array('u.name AS name', 'r.name AS role');

// Selecting via factory
$select = PO\QueryBuilder::select($fields);

// Selecting via the select method
$select = PO\QueryBuilder::select()
    ->select($fields);

// or alternatively
$select = new PO\QueryBuilder\Statements\Select();
$select->select($fields);

// From
$select->from('users u');

// Adding joins
$select->innerJoin('roles r', 'u.id = r.user_id');

$select->toSql();

// SELECT u.name AS name, r.name AS role 
// FROM users u INNER JOIN roles r ON u.idi = r.user_id

INSERT

• Applies placeholders

// Using the factory
$insert = PO\QueryBuilder::insert();

// Or alternatively
$insert = new PO\QueryBuilder\Statements\Insert();

$insert->into('users')->values(array(
    'name'  => 'Jon Doe',
    'email' => 'jon@doe.com'
));

$insert->toSql();

// INSERT INTO users (name, email) VALUES ('Jon Doe', 'jon@doe.com');

UPDATE

• Applies limit
• Applies where
• Applies orderBy
• Applies groupBy
• Applies placeholders

$update = PO\QueryBuilder::update('users');

// or
$update = new PO\QueryBuilder\Statements\Update;
$update->table('users');

// setting values and conditions

$update->set(array(
        'enabled' => 1
    ))->where('email', ':email');

$update->toSql(array(
    'email' => 'admin@email.com'
));

// UPDATE users SET enabled = 1 WHERE email = 'admin@email.com'

DELETE

• Applies limit
• Applies where
• Applies orderBy
• Applies placeholders

$delete = PO\QueryBuilder::delete('users');

// or
$delete = new PO\QueryBuilder\Statements\Delete;
$delete->from('users');

// setting values and conditions

$delete->where('email', ':email');

$delete->toSql();

// DELETE FROM users WHERE email = 'admin@email.com'

WHERE

Every time a where() method is called, the condition is added to the query.

// method signature
$query->where($field, $value, $operator);

// or
$query->where($condition);

// or
$query->where(array(
    array($field, $value, $operator),
    array($condition),
));

// Below some valid examples:

$query->where('email', 'admin@abc.com');
// WHERE email = 'admin@abc.com'

$query->where('email', 'admin@abc.com', '<>');
// WHERE email <> "admin@abc.com"

$query->where('email', '%@google.com', 'LIKE');
// WHERE email <> "LIKE@abc.com"

$query->where('age', 20);
// WHERE age = 20

$query->where('code', 001);
// WHERE code = 001

$query->where('code', array('value' => '001'));
// WHERE code = '001'

$query->where('(code = 1 OR code = 2)'));
// WHERE (code = 1 OR code = 2)

// multiple conditioins, one method call
$query->where(array(
    array('email', 'admin@abc.com', '<>'),
    array('email', '%@google.com', 'LIKE'),
    array('age', 20),
    array('(code = 1 OR code = 2)'),
    array('hash', array('value' => 'SOMEFUNCTION()')),
));

// WHERE condition 1 AND condition 2..

ORDER BY

$query->orderBy('name DESC');
// or
$query->orderBy(array('name DESC', 'age ASC'));

GROUP BY

$query->groupBy('a, b, c');
// or
$query->groupBy(array('a', 'b', 'b'));

LIMIT

$query->limit(2);
$query->limit(2, 1);

Using placeholders

Placeholders are a good way for building your queries when you don't know what values are going to be used (because they depend on the result of a query yet to be executed, for instance).

$insert->into('users')->values(array(
    'name'  => ':name',
    'email' => ':email'
));

$insert->toSql(array(
    'name'  => 'Jon Doe',
    'email' => 'jon@doe.com'
));

// INSERT INTO users (name, email) VALUES ('Jon Doe', 'jon@doe.com');
