Actually, the DA is identified via its id and the id is resolved
via acquisition.

Acquisition is something between static and dynamic binding.
With the appropriate acquisition contexts, you can
let the same Z SQL method instance use different DAs.
It does not provide for the most clear implementation, though.

Your problem has been met often by others. And some of them
extended Z SQL Methods to get dynamic ids.
Maybe, you search the mailing list archives...
