Don't blog bugs, file bug reports (and read the manual before you do that)

Well, I'm disappointed again by John Lim's continual lack of a decent bug report; claiming that you lack the time while having had time to post two blog entries about it is pretty poor.

Let's see the code you're using to call into PDO, John; there's not much time before we release, and without your cooperation, the problems you're seeing won't get addressed.

I'll speculate that John's ADOdb snippet:

<?php
   $rs = $db->Execute("select * from table where a=? and b=?",array('a'=>1,'b'=>2));
 ?>

is trying to bind 'a' and 'b' by parameter names, but the parameters in his query are identified only by their positions (using question marks). I wonder how that is supposed to work? Maybe he should try this:

<?php
   $rs = $db->Execute("select * from table where a=:a and b=:b",array('a'=>1,'b'=>2));
 ?>

It's also worth noting (again) that PDOStatement::getColumnMeta is intentionally unimplemented on this first PDO release, hence its experimental status; in other words, don't use it. Most people don't need this kind of feature anyway.
