Description:
------------
All queries to our MSSQL 2008 database (PDO_dblib with freeTDS) are failing 
since PHP 5.4.17 (same code)

setting freeTDS into debug mode seems to indicate that the SQL queries are not 
sent to the correct database, but to 'master' database, so 
queried object are not found.

FreeTDS log with PHP 5.4.17 :

You can see that the "use [dbName]" is not sent with the same way. The query is 
executed in "master" context, and that's why it's failing.

to Azure SQL"


Test script:
---------------
$pdo = new \PDO('dblib:host=hostname;dbname=dbname', 'username', 'password');
$stmt = $pdo->query('SELECT col FROM table WHERE id = 1');
var_dump($stmt);

Expected result:
----------------
PDOStatement with the matching line from existing table

Actual result:
--------------
false, with this error : General SQL Server error: Check messages from the SQL 
Server [208] (severity 16) => Invalid object name
