Re: Removing JSONB key across all elements of nested array

Hi,

I'm trying to remove JSONB key from following sample JSON

{
    "spec": {
        "id": "485197a6-253a-42b3-9c07-6bac07c02166",
        "buildings": [
            {
                "id": "1b6754b5-c1db-4fdd-af39-32ac173c88cb",
                "equipment": {
                    "selected_inverters": {
                        "15c9e4a2-5dc7-4017-a09f-1d8e75bdfaef": {
                            "count": 1
                        }
                    }
                }
            },
            {
                "id": "0c6d0627-9fd9-4989-819c-35743640052d",
                "equipment": {
                    "selected_inverters": {
                        "125a2eb4-f26f-4d07-89fa-f14df9dac7cf": {
                            "count": 2
                        }
                    }
                }
            }
        ]
    }
}

I've succeeded to do so with following query

SELECT
        my_jsonb #- '{spec,buildings,0,equipment,selected_inverters}') #- '{spec,buildings,1,equipment,selected_inverters}' AS my_jsob
FROM my_table

This feels like a nasty solution, more so.. I may have various number of dicts in the buildings array.

Does anyone have some ideas on how I could implement something like the following?

SELECT
        my_jsonb #- '{spec,buildings,*,equipment,selected_inverters}')  AS my_jsob
FROM my_table
