I am trying to get Doctrine2 Entities, ordered by their ID which apparently is a String even though it contains only Numbers. So what I would like to do is
You should be able to add your own function to implement this feature.
The class would look something like this:
namespace MyProject\Query;
use Doctrine\ORM\Query\AST\Functions\FunctionNode;
use Doctrine\ORM\Query\Lexer;
use Doctrine\ORM\Query\Parser;
use Doctrine\ORM\Query\SqlWalker;
class CastAsInteger extends FunctionNode
{
public $stringPrimary;
public function getSql(SqlWalker $sqlWalker)
{
return 'CAST(' . $this->stringPrimary->dispatch($sqlWalker) . ' AS integer)';
}
public function parse(Parser $parser)
{
$parser->match(Lexer::T_IDENTIFIER);
$parser->match(Lexer::T_OPEN_PARENTHESIS);
$this->stringPrimary = $parser->StringPrimary();
$parser->match(Lexer::T_CLOSE_PARENTHESIS);
}
}
You'll need to register your function:
$config = $em->getConfiguration();
$config->addCustomNumericFunction('INT', 'MyProject\Query\CastAsInteger');
Then you can use it:
SELECT e, INT(e.id) AS HIDDEN orderId FROM Namespace\Bla\MyEntity e ORDER BY orderId
PS: By adding the HIDDEN
keyword, the alias orderId
won't be in the results (and is only used for ordering).
