Re: [Hibernate] Re: AST parser for HQL

[Gavin King]

I don't think we are realistically going to be able to dream up portable 
aliases for everything. I can see an argument for doing it for a couple 
of very important cases like current date. Beyond that I wouldn't really 
like to go there. Note that you can't have both really ... as soon as 
you have too many aliases, they start to clobber the namespace of 
proprietary and user-defined functions.

Note also that the user can define portable aliases for themselves in 
the current parser, by specifying hibernate.query.substitutions.

David,

Excelent point. It looks like a design decision is required here (i.e.
portable aliases vs. proprietary pass-through).  Personally, I like the idea
of portable aliases for special features, as I'm not sure how I'm going to
plug Hibernate's dialect information into the parser.  It's probably not to
hard to do that though, if someone would be kind enough to point me at the
right part of the Hibernate API.  :)
