Question

I have a field at my Java side:

@Column(name = "ads", length = 60, nullable = false)
protected String name;    

so it has an effect at SQL (I use PostgreSQL) side:

"ads" character varying(60) NOT NULL

However I want to add check constraint to it as like:

"ads" character varying(60) NOT NULL CHECK (ads <> '')

How can I define it at Java(hibernate) side?

Answer 1

You can add @NotEmpty annotation on your field.

    @NotEmpty
    @Column(name = "ads", length = 60, nullable = false)
    protected String name;
