When Hibernate loads an object into a Session it creates a state snapshot of the current database state of the object, so that it can perform dirty checking against the snapshot.
As a read only object will never be modified, this snapshot is not needed and memory can be saved.
It is not a JDBC driver error but a configuration needed for Oracle database instance running inside a Docker container.
You need to change $ORACLE_HOME/network/admin/sqlnet.ora append DISABLE_OOB=ON at end of file
Hibernate allows you to create types and override the fetching/saving metods of the types.
Create a type, e.g., InsertableOnly, which on the fetch sets throws away the database value.
Assuming your value is an Integer because you represent prices in cents to avoid rounding issues:
class InsertOnlyInteger extends org.hibernate.type.IntegerType {
public Object get(ResultSet rs, String name) throws SQLException {
return null;
}
}
Then make the Hibernate type of the attribute InsertOnlyInteger (with xml or annotation, as it suits you).

A practical strategy for improving students' reading comprehension skills. Appears relevant to my own context because of the difficulties experienced by learners. This is a simple yet effective strategy which could be incorporated easily into all lessons - I can see its relevance in CBLT and other reading education settings.
Last week's post (The truth about vaccinations: Your physician knows more than the University of Google) sparked a very lively discussion, with comments from several people trying to persuade me (and the other readers) that their paper disproved everything that I'd been saying. While I encourage you to go read the comments and contribute your…
