How can I select a property from an object type column in postgresql

Question

This is table:

Id    source_data           name

1.    {id: '1', value: 5}.  Ahmed
2.    {id: '3', value: 7}.  Aadi

I want to do this kind of query: Select Id, source_data.value, name From table

Answer 1

Assuming the data type of your source_data column is type json or jsonb :

SELECT
    id,
    source_data ->> 'value'
    name
FROM my_table

If it is of type text , you can cast it into json before:

SELECT
    id,
    source_data::json ->> 'value'
    name
FROM my_table
