but this check is something hibernate generates. its not db dependent AFAIK.
Not sure which DB you are using, but for example I've noticed that HSQL seems to not parse the entire statement string upfront which can lead to issue like this. It leaves parsing certain pieces relative to its internal working datasets; if there are no results in those working sets, you get no errors. Specifically I have seen this with correlated sub-queries.

Hi,
while working on Critiera i "bumped" into this funny behavior:
Doing the following Critieria on an empty db gives no error:
s.createCriteria(Student.class) .add( Expression.like("name", "Gavin", MatchMode.START) ) .addOrder( Order.asc("name") ) .createCriteria("enrolments", "e") .addOrder( Order.desc("year") ) .addOrder( Order.desc("semester") ) .createCriteria("course") .addOrder( Order.asc("description") ) .setProjection( Expression.projection() .add( Expression.property("this.name") ) .add( Expression.property("e.year") ) .add( Expression.property("e.semester") ) .add( Expression.property("courseCode") ) .add( Expression.property("description") ) ) .uniqueResult();
but when data is available i get an error saying that courseCode is not available on Student - which is totally correct.
(using explicit criteria aliases solves it)
I'm just wondering why this is not discovered when the query gives no result - it should still be able to tell that courseCode is not on Student - is this expected behavior ?
