WIthout any changes, for this use case I usually just construct association
objects with all their state at
Hello.
I tried many different configurations to connect to mysql5 server using

I always end with an error due to the fact that some string data is of type

Here is the following code which works. Using the RowProxy didn't work

May be I am wrong,
But I guess you have not used stored procedures?
If speed and performance is important along with scalability, then
forget database independence and use stored procedurs.
I have built a small function called execProc() which I can send you off
