These are annoying to support. I would like to see in v5 some kind of Database Proxy that passes requests through to the driver for most cases but "captures" the actual SQL query for Test Mode. I think that would be a much better approach than trying to adjust all our return types.

[kenjis]

Yes, the return types are not good, should be bool only.
