[hibernate-dev] 6.0 - Query literal rendering

[Christian Beikov]

May I ask what happened to the idea of not rendering through the 
literals at all and just "inject" them into the result tuple? We could 
even go as far as allowing expressions on constant values to be 
evaluated in memory instead of sending that to the DB.

Other than that, the settings seem ok, but how does that affect 
subqueries? The same way? Or are subqueries the exception?

Regards,

Christian
