When you turn on Hibernate’s SQL logging during Java development (e.g. log4j.logger.org.hibernate.SQL = debug, console), you won’t see values (only a ?) which will be/are used in a query.
select this_.id as ID113_4_ ........ from INCOMINGMESSAGE ... where this_.STATUS=? and this_.FOO=?
Now turn on some extra logging (log4j.properties):
log4j.logger.org.hibernate.type = trace, console
Now you’ll see some extra information like the type (StringType / EnumType / etc.) and the value:
select this_.id as ID113_4_ ........ from INCOMINGMESSAGE ... where this_.STATUS=? and this_.FOO=? DEBUG org.hibernate.type.EnumType - Binding 'UNHANDLED' to parameter: 1 DEBUG org.hibernate.type.StringType - Binding 'Bar' to parameter: 2
Note: When your application uses big queries then you’ll get a lot of extra logging\!
