如何更新 postgresql db 中嵌套 jsonb 属性的值

Question

{
"personalDetails": {
    "First Name": "Paul", 
    "Last Name": "Jamessen", 
    "Work Class": "A+", 
    "Working Unit": "Management", 
    "email": "demo@demo.com"
    }
}

I want to update the records whose Working Unit is Management to Work Class A, like below

{
"personalDetails": {
    "First Name": "Paul", 
    "Last Name": "Jamessen", 
    "Work Class": "A", 
    "Working Unit": "Management", 
    "email": "demo@demo.com"
    }
}

Answer 1

You can use jsonb_set()

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

Answer 2

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