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())
