Hi,

How do we put contraint of a combination of two are more fields has to be unique say phone number and mobile number of a person has to be unique etc.

I do understand @Column(updatable = false, unique = true, nullable = false, length = 50)

would result in one field to be unique. I wish to say here that is xyz filed and abc field to be unique rather than just saying xyz is unique and abc field is unique.

Regards,
Nagendra
