> It is currently not possible to declare a SQL string that contains existing
> JSON as valid JSON for JSON_OBJECT. Something like
> {code:java}
> JSON_OBJECT(KEY 'K' VALUE '\{"value": 42}') returns \{"K", "{"value": 42}"}
> {code}
> Where the value is a string a not a json object.
> We should support the JSON() function, at least initial support for it until
> this function returns the JSON datatype.
>
> Example:
> {code:java}
> jsonObject(JsonOnNull.NULL, "nested", json('{"value": 42}'))
> JSON_OBJECT(KEY 'K' VALUE JSON('{"value": 42}'))
> // {"nested":{"value":42}}{code}
