Question

I am trying to query hibernate for given scenario:

My Data Model

Class Communication:

variables : subject, sentTo, creator.

Now lets say there are some notes exchanged between usera and userb. I want to find all those notes by a hibernate query. I have written below my query string.

select note from Communication n where n.subject=:subject and ((n.sentTo=:sentto and n.creator=:creator) or (n.sentTo:creator and n.creator=:sentto))

But hibernate is not able to parse this query. Please suggest what to do?

Exception the parser throws

Answer 1

Try using:

select note from Communication n where n.subject=:subject and ((n.sentTo=:sentto and n.creator=:creator) or (n.sentTo:creator and n.creator=:sentto))

Alias for Communication is missing and you are trying to access it through its alias 'n' (that’s not defined)

Thanks
