[Help]How do not cache mysql client result (no replies)

I got the same problem in http://dev.mysql.com/doc/refman/5.0/es/out-of-memory.html.

My c++ program will invoke a lot of SQL queries by some requirements. I find it can be solved by add options parameter when using a DSN connection. But what's the connection parameter name via mysql c++ connector driver?

Thank you for your reply.
