I am doing a PDO::exec command on multiple updates:
$MyPdo->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY,true);
$MyPdo->exec("update t1 set f1=1;update t2 set f1=2");
I am doing it inside a transaction, and I keep getting:
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.
those are the only query/ies
