PDO::PARAM for type decimal?

Question

I have 2 database fields

`decval` decimal(5,2)
`intval` int(3)

I have 2 pdo queries that update them. The one that updates the int works ok

$update_intval->bindParam(':intval', $intval, PDO::PARAM_INT);

but I can't update the decimal field. I've tried the 3 ways below, but nothing works

$update_decval->bindParam(':decval', $decval, PDO::PARAM_STR);
$update_decval->bindParam(':decval', $decval, PDO::PARAM_INT);
$update_decval->bindParam(':decval', $decval);

It seems the problem is with the database type decimal? Is there a PDO::PARAM for a field of type decimal? If not, what do I use as a workaround?

Answer 1

use dot instead of comma for the separator?

Answer 2

There isn't any PDO::PARAM for decimals / floats, you'll have to use PDO::PARAM_STR.

Answer 3

I found out, looking for a way of storing DOULBEs using PDO, that if you don't provide the third argument (i.e. PDO::PARAM_*) it uses some kind of magic and stores the number correctly. So maybe if you just left PDO to worry about the parameter type and merrily bind :decval to a $decval and hop along to the next task :-))
