SQL Builder for PHP, with JOIN support?

Question

Are any of you aware of a library that helps you build/manipulate SQL queries, that supports JOIN\'s?

It would give a lot of flexibility i\'d think if you have somet

Answer 1

Try magsql https://github.com/maghead/magsql, a SQL builder designed for performance written in PHP, comes with join support and cross-platform SQL generation.

It's currently used in the fastest pure PHP orm "maghead"

Answer 2

Maybe you can try an ORM, like Propel or Doctrine, they have a nice programmatic query language, and they return you arrays of objects that represent rows in your database...

For example with Doctrine you can do joins like this:

$q = Doctrine_Query::create();
$q->from('User u')
->leftJoin('u.Group g')
->innerJoin('u.Phonenumber p WITH u.id > 3')
->leftJoin('u.Email e');

$users = $q->execute();

And with Propel:

$c = new Criteria(AuthorPeer::DATABASE_NAME);

$c->addJoin(AuthorPeer::ID, BookPeer::AUTHOR_ID, Criteria::INNER_JOIN);
$c->addJoin(BookPeer::PUBLISHER_ID, PublisherPeer::ID, Criteria::INNER_JOIN);
$c->add(PublisherPeer::NAME, 'Some Name');

$authors = AuthorPeer::doSelect($c);

and you can do a lot more with both...

Answer 3

FluentPDO looks nice if you're already using PDO: https://github.com/envms/fluentpdo

Answer 4

I would advise using a PHP framework such as Symfony which uses Propel by default and can use Doctrine if you wish.

CakePHP also uses an ORM, but I don't know which one.

Answer 5

You can use lenkorm it's very easy:

select('contents)->left('categories ON categories.category.id = contents.category_id)->where('content_id = 1')->result();

or you can use as:

select('contents)->left('categories->using(categoru_id)->where('content_id = 1')->result();

Download it from github

Answer 6

I use the query builder from the phptoolcase library, it uses pdo connector, has join support.

You can use it with the connection manager fro the library to setup multiple database connection very quickly.
