Original Pull Request: https://github.com/doctrine/orm/pull/717

State: closed
Merged: Yes

Using a query parameter of which the name starts with an underscore results in a QueryException. For example:

$q = $em->createQueryBuilder()
    ->select("u")
    ->from("User", "u")
    ->where("u.username = :_name")
    ->setParameter("_name", "bar")
    ->getQuery();

Results in:

Invalid parameter format, : given, but :<name> or ?<num> expected.

This happens because of a bug in the Lexer, which recognizes :_name as two tokens (the : as the start of a input parameter, _name as an identifier). The attached patch changes the regular expression for input parameters to allow identifiers starting with a letter or underscore.
