Use on conflict do nothing:
insert into employee values(1, 'K1') on conflict (empid) do nothing;
insert into employee values(1, 'K1') on conflict (empid) do nothing;
insert into employee values(2, 'K2') on conflict (empid) do nothing;
This can be combined with a PreparedStatement and batching if needed.
