Description:
------------
Hy,

I use an oracle database and my locale setting for the decimal point is ",".
When I run a SELECT query with a float datatype column, the result is a string datatype value and the decimal separator is ','.
And PHP don't recognize this as a number.

Why oracle column datatypes are not kept?


Reproduce code:
---------------
$oPDOStmt = $oConn->query("SELECT 12.34 AS NB FROM DUAL");
$arrResult = $oPDOStmt->fetch(PDO::FETCH_ASSOC);
print_r($arrResult);
print gettype($arrResult["NB"]);

Expected result:
----------------
Array
(
    [NB] => 12.34
)

Actual result:
--------------
Array
(
    [NB] => 12,34
)

The string conversion is not a bug in the driver. Its how PDO has been designed. FETCH:ASSOC will always perform a string conversion regardless of the driver. Use bindColumn():

$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, 0);
$stmt = $db->query("SELECT 1");
$stmt->bindColumn(1, $value, PDO::PARAM_INT);
$stmt->fetch(PDO::FETCH_BOUND)

Not respected locale setting might be a bug. Check again using bindColumn().

The problem is still here.
I have a french system with the decimal separator ","

I would like to get a float number (e.g. 12.34). When is use bindColumn(), I get 12 if I use the PDO::PARAM_INT or 12,34 if I use the PDO::PARAM_STR.

Is it possible to retreive a float number with PDO in this condition ?
