PostgreSQL更新jsonb数组列中的值 [英] Postgresql update a value in a jsonb array column

问题描述

我有一个带有jsonb的表，并且此数据位于其中:

I have one table with a jsonb and this data inside:

[
{
    "valor": "2025,79",
    "parcela": 46,
    "vencimento": 1570503600000
},
{
    "valor": "1987,7",
    "parcela": 47,
    "vencimento": 1573182000000
},
{
    "valor": "1950,47",
    "parcela": 48,
    "vencimento": 1575774000000
},
{
    "valor": "1912,88",
    "parcela": 49,
    "vencimento": 1578452400000
}

]

但是现在我需要在所有行中将"vencimento"中的值从1573182000000更改为"10/10/2010"

but now I need in all row, alter the value in "vencimento" from 1573182000000 to "10/10/2010"

有可能吗?

使用此代码，我可以将数组拆分为列并更改te值

with this code I can split the array in columns and change te value

SELECT id, jsonb_set(d, '{vencimento}',
 quote_ident(to_char(to_timestamp(cast((d -> 'vencimento')::varchar as bigint) / 1000)::date, 'dd/mm/yyyy'))::jsonb
) 
    FROM notificato.requerimento, jsonb_array_elements(parcela) d where id = 1;

但是如何更新我的行?

推荐答案

使用

Collect the values back to a jsonb array with jsonb_agg and assign that to your column:

UPDATE notificato.requerimento
SET parcela = (SELECT jsonb_agg(
  jsonb_set(d, '{vencimento}', to_jsonb(to_char(to_timestamp((d ->> 'vencimento')::bigint / 1000)::date, 'dd/mm/yyyy'))
) FROM jsonb_array_elements(parcela) d)
WHERE id = 1;
