Hi

when I execute a prepared query which use twice, or more, a same
parameters, it 
returns an error : in french : ERREUR:  n'a pas pu déterminer le type
de données 
du paramètres $3

ie. : this query don't works
$sReq = 'select *
	from categorie
	left join budget on bud_cat = cat_cod and bud_moi = :month and bud_ann
= 
:year
	left join operation on ope_cat = cat_cod and ope_moi = :month and 
ope_ann = :year
	where cat_cod = :categorie';
$rCategorie = $oAppli->getDb()->prepare($sReq);
$rCategorie->bindParam(':month', date('m'));
$rCategorie->bindParam(':categorie', $sCategorie);
$rCategorie->bindParam(':year', date('Y'));
if ($rCategorie->execute())

but if I add "--  :year :categorie :month" at the beginning of the
query, it 
works !!!
I thinks PDO don't like seeing a repeated parameter before seens all the

parameters (the :month appears twice before :categorie, almost with the
comment 
at the beginning, PDO see all parameters at start)

Sorry for my english I'm french guy.

Thks

Test script:
---------------
//don't work
$sReq = 'select *
	from categorie
	left join budget on bud_cat = cat_cod and bud_moi = :month and bud_ann
= :year
	left join operation on ope_cat = cat_cod and ope_moi = :month and
ope_ann = :year
	where cat_cod = :categorie';
$rCategorie = $oAppli->getDb()->prepare($sReq);
$rCategorie->bindParam(':month', date('m'));
$rCategorie->bindParam(':categorie', $sCategorie);
$rCategorie->bindParam(':year', date('Y'));
if ($rCategorie->execute())

//works fine

$sReq = '--  :year :categorie :month
	select *
	from categorie
	left join budget on bud_cat = cat_cod and bud_moi = :month and bud_ann
= :year
	left join operation on ope_cat = cat_cod and ope_moi = :month and
ope_ann = :year
	where cat_cod = :categorie';
$rCategorie = $oAppli->getDb()->prepare($sReq);
$rCategorie->bindParam(':month', date('m'));
$rCategorie->bindParam(':categorie', $sCategorie);
$rCategorie->bindParam(':year', date('Y'));
if ($rCategorie->execute())
