Jira issue originally created by user bountin:
I wanted to use COALESCE in DQL with a function (e.g. CURRENT_TIMESTAMP()). If I run this DQL, I receive a syntax error exception like this one:
montbook:marlow mprebio$ php scripts/doctrine.php orm:run-dql "select COALESCE(CURRENT_TIMESTAMP()) from Project\Entity\User user"
[Syntax Error] line 0, col 33: Error: Expected Doctrine\ORM\Query\Lexer::TCLOSEPARENTHESIS, got '('
I've traced this error to Doctrine\ORM\Parser::ScalarExpression() which tries to interpret the currenttimestamp function as a SimpleArithmeticExpression or as a StateFieldPathExpression (first if). As far as I understand this part of the parser, the function call should lead to the if part with $this->_isFunction(). Therefore I added a "and !$this->isFunction()" to the first if clause. After this change everything works as expected: The above query returns the current timestamp (many times because of the from since DQL needs a from part).
Reordering the ifs should work too.
Comment created by bountin:
Also the documentation at http://www.doctrine-project.org/docs/orm/2.1/en/ only mentions COALESCE in the EBNF but not in the real documentation part. At first I thought that Doctrine doesn't support coalesce at all.
Comment created by @guilhermeblanco:
COALESCE does not exist on 2.1.
COALESCE is a 2.2-DEV, so use latest master.
Marking as invalid, since we won't change 2.1 to support this.
