given this table

| parent | payload |
| --- | --- |
| 1 | `{ a: 7, b: 3 }` |
| 2 | `{ a: 7, c: 3 }` |
| 1 | `{ d: 3, e: 1, f: 3 }` |

I want to update children of `1` and remove any attribute `X` where `payload->X` is `3`.

after executing the query the records should look like this:

| parent | payload |
| --- | --- |
| 1 | `{ a: 7 }` |
| 2 | `{ a: 7, c: 3 }` |
| 1 | `{ e: 1 }` |

```
    update records set payload=?? where parent = 1 and ??

```
