Better error handling in named queries with empty collection parameters

[CmdrDats]

Currently, when you call a named query with a collection parameter, it spits out a nasty sql error because the IN () is empty. If a parameter is a collection but empty, it should info out a warning, but return an empty list. Most of the time if an IN () is empty, it means there shouldn't be any results anyhow.
