I can't reproduce it using sqlite.

<?php

$x = new pdo('sqlite::memory');
$x->query('create table if not exists foo (x int)');
$x->query('insert into foo values (1)');
$x->query('insert into foo values (2)');
$y = $x->prepare('select x from foo 
where 
	-- x = ?
	x = ?');
var_dump($y->execute(array(2)));
var_dump($y->fetch());
var_dump($y->errorInfo());




bool(true)
array(2) {
  ["x"]=>
  string(1) "2"
  [0]=>
  string(1) "2"
}
array(1) {
  [0]=>
  string(5) "00000"
}

Which SGBD are you using?

I'm quite sure this is a problem with PS emulation, I have no test system at hand ...

Not sue how to handle it in our parser:The SQL standard wants, afaik, a space behind the --, MySQL fr instance doesn't need it.Additionally the same problem should exist with /* */ comments, which are implemented in different way, too (MySQL need no */)

Following the standard might still break stuff, not following the standard might break other case, making it driver dependent will give a mess...

Thanks for the quick response, I should have stated this was using MySQL PDO driver.
