Hi,

I have a table with name and id. Id is primary key and auto incremented.

I am using hibernate 3.2 and in my mapping file i have specified unique="true" in the property for name column.

But still I am able to add same name more than once.

I predict my code should throw some exception when i try to add duplicate name but it is not.

What might be the reason

Thanks

IIRC the unique-attribute is used for table generation and adds a constraint to that column. If you created the table yourself and didn't add a constraint, the behaviour is correct - Hibernate doesn't check constraint violations at runtime.
