Re: Stored procedures, PDO, and PHP issue

Hi Eric,

What about setting your SQL text to use $1 and $2 as the parameter
values?  I'm currently doing this in the C API (as I type this!) so not
sure if this will work in PHP PDO.

$stmt = $db->prepare("SELECT is_password_expired($1::integer,
$2::varchar)");

When you say "this completely fails" - in what respect?  What errors do
you get?  Also have you tried making sure your PHP $userId is an integer
not a string - e.g. settype($userId, 'integer');  Again I'm not sure if
this has a bearing on the PDO stuff as I've never used it.

Regards,
Andy
