I am having a hard time understanding how to make sure the right types (esp. in the case of dates) are passed to the db, partly because of a lack of concrete examples in the docs and partly because the docs are a bit elliptic: the docs merely say that "the types are selected by consulting arguments varTypes and typeInfo", which is not nearly enough to understand what is actually happening. Where can I find either more examples or a fuller discussion? Thanks, -- O.L.
