如何更新 postgresql db 中嵌套 jsonb 属性的值

问题描述

{
"personalDetails": {
    "First Name": "Paul","Last Name": "Jamessen","Work Class": "A+","Working Unit": "Management","email": "[e-mail]"
    }
}

我想将工作单位为管理类的记录更新为工作类A，如下图

{
"personalDetails": {
    "First Name": "Paul","Work Class": "A","email": "[e-mail]"
    }
}

解决方法

您可以使用jsonb_set()

update the_table
  set the_column = jsonb_set(the_column,'{personalDetails,"Work Class"}','"A"')
where the_column #>> '{personalDetails,"Working Unit"}' = 'Management';

,

update table_name 
set column_name = jsonb_set("column_name",'{"personalDetails",'"A"'::jsonb) 
where column_name::json->'personalDetail'->>'Working Unit' = 'Management' ;
