perbarui beberapa baris dalam satu kueri tetapi input yang kami harapkan adalah dari objek json dari banyak data

Anda dapat melakukan penyisipan massal berdasarkan dokumen json. Anda harus memformat ulang dokumen karena format yang ditunjukkan dalam pertanyaan aneh dan tidak praktis.

Contoh kerja lengkap:

create table example(id int primary key, email text, last_name text, first_name text);

with jsondata(jdata) as (
    values
    (
    '[
        {"id": 1, "email": "[[email protected]]", "first_name": "John", "last_name": "Doe"},
        {"id": 2, "email": "[[email protected]]", "first_name": "Robert", "last_name": "Duncan"},
        {"id": 3, "email": "[[email protected]]", "first_name": "Ram", "last_name": "Das"},
        {"id": 4, "email": "[[email protected]]", "first_name": "Albert", "last_name": "Pinto"},
        {"id": 5, "email": "[[email protected]]", "first_name": "Robert", "last_name": "Peter"},
        {"id": 6, "email": "[[email protected]]", "first_name": "Christian", "last_name": "Lint"},
        {"id": 7, "email": "[[email protected]]", "first_name": "Mike", "last_name": "Hussey"},
        {"id": 8, "email": "[[email protected]]", "first_name": "Ralph", "last_name": "Hunter"}
    ]'::jsonb)
)

insert into example 
select (elem->>'id')::int, elem->>'email', elem->>'last_name', elem->>'first_name'
from jsondata,
jsonb_array_elements(jdata) as elem;

Hasilnya:

select *
from example

 id |     email     | last_name | first_name 
----+---------------+-----------+------------
  1 | [[email protected]] | Doe       | John
  2 | [[email protected]] | Duncan    | Robert
  3 | [[email protected]] | Das       | Ram
  4 | [[email protected]] | Pinto     | Albert
  5 | [[email protected]] | Peter     | Robert
  6 | [[email protected]] | Lint      | Christian
  7 | [[email protected]] | Hussey    | Mike
  8 | [[email protected]] | Hunter    | Ralph
(8 rows)    

Jika Anda ingin memperbarui tabel (bukan memasukkan ke dalamnya):

with jsondata(jdata) as (
    -- values as above
)

update example set
    email = elem->>'email', 
    last_name = elem->>'last_name', 
    first_name = elem->>'first_name'
from jsondata,
jsonb_array_elements(jdata) as elem
where id = (elem->>'id')::int;
