Great work. This will make further enhancements to the Select clause much
easier.
Here are a few more queries from the test package that I use to test some of
the more
recent (and not so well documented) changes to the select clause, eg,
dialect functions.
This one is not recent but affects the parser somewhat and was not in your
test suite.
select new net.sf.hibernate.test.S(s.count, s.address) from s in class
Simple
These a few tests for delects functions. From the tests it would look like
it would work as it stands although
problem maybe with some functions that have no arguments, for example,those
that have no parenthesis, eg, Oracle dialect
select s.name, sysdate, trunc(s.pay), round(s.pay) from s in class Simple
Just for the record, Nested examples.
select abs(round(s.pay)) from s in class Simple
select trunc(round(sysdate)) from s in class Simple
The current parser cannot do it at the moment (it is a pain in current form)
but multiple arguments comma
separated is easy for you to add, so we then hook into it,
select round(s.pay, 2) from s in class Simple
being very greedy it would be also real nice to include the usual literal
types and operators in the select
clause. These we also cannot do at the moment.
I do assume that this will get integrated in the 2.2 series as it is fairly
major surgery to hook this into the backend.
Look forward to it.
