Hello,

it seems to me like a bug. If i simply use 




*array(        PDO::MYSQL_ATTR_INIT_COMMAND => ' SET NAMES UTF8',)*


as driver option, it works like a charm, but if i switch to





*array(        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET 
sql_mode="STRICT_ALL_TABLES"; SET NAMES UTF8',)*

it will cause an Exception:

Doctrine\DBAL\DBALException File: 

/srv/http/www/vendor/doctrine/dbal/lib/Doctrine/DBAL/DBALException.php:91

Message: 

An exception occurred while executing 'SELECT t0.id AS id1, t0.type AS type2, 
t0.name AS name3 FROM demo t0':

SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other 
unbuffered queries are active.  Consider using PDOStatement::fetchAll().  
Alternatively, if your code is only ever going to run against mysql, you may 
enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY 
attribute.

Even if i add PDO::MYSQL_ATTR_USE_BUFFERED_QUERY it doesn't change anything




*array(        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET 
sql_mode="STRICT_ALL_TABLES"; SET NAMES UTF8',        
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true,)*
