Autocommit is not working well with firebird :
In fact :
Create a selecatble stored procedure that juste insert a row in a table

Connect to pdo firebird database
Use autocommit :
$db->setAttribute( PDO::ATTR_AUTOCOMMIT, 1 );

Call the stored procedure
Close the connection

Do a select of tha table : the row is not present !!
Now insert a commit just before closing connection.
Execute the script : the row is present !!

Expected result:
----------------
The transaction should be commited

Actual result:
--------------
The transaction is not commited
