PHP Bug Type: PDO related
Bug description: Named placeholder is not bound correctly with Subqueries
Description:
------------
When binding to a named placeholder in a prepared-statement using
mysql-5.0.24-r1 causes unpredictable behaviour.
With PHP 5.1.4 the query goes correct.
Reproduce code:
---------------
<?php
$dbh = new PDO('mysql:host=localhost;dbname=mysql', 'root', 'pwd');
$query1 = "SELECT * FROM user WHERE User=:user AND Host IN (SELECT Host
FROM user WHERE User=:user)";
$query2 = "SELECT * FROM user WHERE Host IN (SELECT Host FROM user WHERE
User=:user) AND User=:user";
$stm1 = $dbh->prepare($query1);
$stm1->bindValue(':user', 'root');
$stm1->execute();
print count($stm1->fetchAll()).'<br>';
$stm2 = $dbh->prepare($query2);
$stm2->bindValue(':user', 'root');
$stm2->execute();
print count($stm2->fetchAll()).'<br>';
Expected result:
----------------
Should return: (like it does using the command-line-client)
2
2
Actual result:
--------------
It returns:
2
