doctrine-orm - Doctrine 2 查询生成器的问题

Question

我正在尝试使用 Doctrine 2 构建查询

$qb = $em->createQueryBuilder()
                  ->select('*')
                  ->from('Countries','c')
                  //getDQL
                  ->getQuery();

  echo "<pre>";
echo ($qb->execute());
echo "</pre>";
die;

出于某种原因，我收到一个错误:

Fatal error: Uncaught exception 'Doctrine\ORM\Query\QueryException' with message '[Syntax Error] line 0, col 7: Error: Expected IdentificationVariable | StateFieldPathExpression | AggregateExpression | "(" Subselect ")" | ScalarExpression, got '*'' in /home/dodo/doctrine-orm/Doctrine/ORM/Query/QueryException.php on line 42

没有“全局通配符”这样的东西 - 你应该使用 c.* .
