Bug Type: PDO related
Operating System: Linux Debian Sarge 3.1
PHP Version: 5.2.1

PHP v 5.2.6
MySQL v 5.0.51b-community-nt

Similar (though not exactly) usage of PDO to run a stored procedure w/
a parameter that sets the number in a limit clause does not replicate
error.
$dbc = new DBO;
$dbc->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sproc = $dbc->prepare(CALL spLimitProc ?);
$sproc->bindParam(1,$limit, PDO::PARAM_INT);
$result = $sproc->execute();
Result returns table rows as expected (similar to direct MySQL sproc
call).
Perhaps resolved or not experienced across platforms?

This problem is still not fixed in PHP 5.2.6

Emulation is wrong if it doesn't work. Numbers after LIMIT should not
be quoted.

Description:
------------
The following emerged after upgrading from 5.2.0 to 5.2.1 and has been
checked in both versions: the error only occurs in 5.2.1 .
When passing parameters into a LIMIT clause using PDO::execute(), it
appears that PDO is quoting the parameters, which causes MYSQL to throw
an error.
FYI: PDO_MYSQL is built against MySQL client library 5.0.18.
Reproduce code:
---------------
$dbh = new PDO('mysql:localhost;dbname=my_db', 'user', '' );
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try{
$query = $dbh->prepare( 'SELECT * FROM some_table LIMIT :start,
:limit' );
if ( $query->execute ( array ( 'start' => 0, 'limit' => 10 ) ) )
{
while ( $row = $query->fetch ( PDO::FETCH_ASSOC ) )
{
print_r($row);
}
$query->closeCursor();
}
} catch( Exception $e ){
print_r( $e );
}
Expected result:
----------------
A number of rows are returned.
Actual result:
--------------
An exception is thrown:
PDOException Object
