i have error sqlstate[42s02]: base table or view not found: 1146 table 'artel.developer_codeuserreference' doesn't exist . need find developers has reference or whohas not reference.help

it saying table codeuserreference doesn't exist

so 

->join(d.newreference, 'm')

is not going work.

can please show header of codeuserreference class?

have done migrations add table database?

check if command create file difference: doctrine:migrations:diff

public function getdeveloperswithrefernce() {     $qb = $this->getentitymanager()->createquerybuilder('d');      $qb         ->select('d')         ->from('artelprofilebundle:developer', 'd')         ->leftjoin('d.newreference', 'm')         ->where('m.codereference null')         ->andwhere('d.password null')          ->getquery();     $query = $qb->getquery();     $results = $query->getresult();      return $results; }
