Hi!

What might be reasons for running in the quoted exception upon a HQL select, when there is actually no NULL value in the respective field in the database?

I've checked the database multiple times. I've manually submitted the query statement produced by hibernate (extracted from debug). Null values for the respective field are actually never returned. However, the corresponding row in the database is in fact nullable. Does hibernate care about the data base definition?

I know, I could simple change the filed to a wrapper type, but we have a number of such fields in a legacy application and this only occurs upon a single query. I'm just wondering about the actual reason for getting this exception only with a single property. Any hints would be greatly appreciated.
