Hi,

This query is fine:

[code]
from Annotation a
where a.bookId = :bookid and a.pageIndex = :pageindex and (a.type != 1 or a.destBookId is null)
[/code]

This query causes an exception when hibernate loads because it claims there is an error in this named query:

[code]
from Annotation a
where a.type == 1 and a.destBookId is null and a.bookId == ?
[/code]

Its making no sense at all!

Andy

Is it possible to use Annotation (which is a Java interface) in a Hibernate query?
Won't Hibernate try to do a.getBookId(); on this interface http://www.uni-muenster.de/ZIV.BennoSueselbeck/java/jdk1.5.0_01/docs/api/java/lang/annotation/Annotation.html?

What is the Exception / Stacktrace you are getting?

Disregard my post. I didn't understand the exact question correctly that the first query works.

I don't know for sure what might be wrong ... but in the aboven you use = :parametername to check parameters, and in the latter you use == ? for parameter solving.
Isn't there a problem overthere?

Still, what is the stacktrace?
