Annotation Type ManyToMany->>>>>Oracle

Example 1:

    // In Customer class:

    @ManyToMany
    @JoinTable(name="CUST_PHONES")
    public Set<PhoneNumber> getPhones() { return phones; }

    // In PhoneNumber class:

    @ManyToMany(mappedBy="phones")
    public Set<Customer> getCustomers() { return customers; }

    Example 2:

    // In Customer class:

    @ManyToMany(targetEntity=com.acme.PhoneNumber.class)
    public Set getPhones() { return phones; }

    // In PhoneNumber class:

    @ManyToMany(targetEntity=com.acme.Customer.class, mappedBy="phones")
    public Set getCustomers() { return customers; }

    Example 3:

    // In Customer class:

    @ManyToMany
    @JoinTable(name="CUST_PHONE",
        joinColumns=
            @JoinColumn(name="CUST_ID", referencedColumnName="ID"),
        inverseJoinColumns=
            @JoinColumn(name="PHONE_ID", referencedColumnName="ID")
        )
    public Set<PhoneNumber> getPhones() { return phones; }

    // In PhoneNumberClass:

    @ManyToMany(mappedBy="phones")
    public Set<Customer> getCustomers() { return customers; }
