[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-5556) Allow primitive properties to default to non-nullable in annotations

[Steve Ebersole (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5556?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steve Ebersole closed HHH-5556.
-------------------------------

    Resolution: Rejected

This works exactly as you want if there is no @Column annotation present.  And, unfortunately, if there is a @Column annotation present there is no way for us to know whether it specified nullable explicitly since it is a primitive value.  So when reading it, @Column(name="abc") and @Column(name="abc, nullable=true) look exactly the same

>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5556
>             Project: Hibernate Core
>          Issue Type: New Feature
>          Components: annotations
>    Affects Versions: 3.5.0-Final
>         Environment: Hibernate 3.3.1, PostgreSQL 8.3
>            Reporter: Daniel Migowski
>
> We have an entity attribute like this:
>     @Column(updateble=false)
>     double quantityInInvoice;
> This column is considered nullable in the Hibernate meta data because the @Column annotation contains another attribute named "nullable" which defaults to true. 
> I don't know if this is an specification error but for primitive datatypes the column should never be nullable IMHO. We found this out because we modified Hibernate locally to create and update the NOT NULL contraints on tables in the database.
> Workaround: Set nullable=false explicitely in the @Column annotation.
