Question

The attempt to register the soundex function results in:

[Syntax Error] line 0, col 106: Error: Expected end of string, got
‘SOUNDEX’

Class definition:

use Doctrine\ORM\Query\AST\Functions\FunctionNode;

/**
 * SoundexFunction ::= "SOUNDEX" "(" StringPrimary  ")"
 */
class SoundexFunction extends FunctionNode
{
    public $stringExpression = null;

    public function parse(\Doctrine\ORM\Query\Parser $parser)
    {
        $parser->match(Lexer::T_IDENTIFIER);
        $parser->match(Lexer::T_OPEN_PARENTHESIS);
        $this->$stringExpression = $parser->StringPrimary();
        $parser->match(Lexer::T_CLOSE_PARENTHESIS);

    }
    public function getSql(\Doctrine\ORM\Query\SqlWalker $sqlWalker)
    {
        return 'SOUNDEX(' .
            $this->$stringExpression->dispatch($sqlWalker) .
        ')';
    }
}

config.yml snippet:

orm:
    auto_generate_proxy_classes: "%kernel.debug%"
    entity_managers:
      default:
        auto_mapping: true
        dql:
          string_functions:
            soundex: Mana\ClientBundle\DQL\SoundexFunction

query function:

protected function getMatches($incoming) {
    $em = $this->getDoctrine()->getManager();
    $fname = $incoming['fname'];
    $sname = $incoming['sname'];
    $sql = "select id, active, fname, sname, dob, phys_addr, phys_city
        from ManaClientBundle:Client where SOUNDEX(fname) = SOUNDEX(:fname) and
        SOUNDEX(sname) = SOUNDEX(:sname)
        order by sname, fname";
    $query = $em->createQuery($sql)
        ->setParameters(array(
            'fname' => $fname,
            'sname' => $sname,
        ));
    return $query->getResult();
}

Geo, not sure why it’s not working for you. I tried it with the QueryBuilder and it worked. However, I did have to replace your usages of $this->$stringExpression with $this->stringExpression.

Edit:

I just tested your code in a bare application, and the issue isn’t in the SOUNDEX, it’s in your SQL. Try assigning an SQL alias to your entity:

$sql = "select client.id, client.active, client.fname, client.sname, client.dob, client.phys_addr, client.phys_city
        from ManaClientBundle:Client client where SOUNDEX(client.fname) = SOUNDEX(:fname) and
        SOUNDEX(client.sname) = SOUNDEX(:sname)
        order by client.sname, client.fname";
