@Column attribute validation

Hi,

Assume I have the following column definition:

Code:

@Column(name = "account_no", nullable = false, length = 10)
public String getAccountNo() {
    return this.accountNo;
}

If I create a new entity, set the account number to null, and try to save the entity, I get a HibernateException without ever touching the database.

If I create a new entity, set the account number to a string longer than 10 digits, and try to save the entity, I get a MysqlDataTruncation from the database.

Hibernate seems to be checking the nullable attribute before trying to save, but not checking the length attribute. Is this expected behaviour?

Thanks,
mers

Yeah, this is actually how Hibernate will work.
