Re: postgres json: How to query map keys to get children

Perfect your snippet gave me some clues...
It looks as follows:
SELECT json_array_elements(skill_type.Skill->'value')->>'Name' as NameFROM ( SELECT to_json(json_each(ResourceDocument->'Skill')) as Skill FROM testdepot.Resource) skill_type
to_json returns a key value map which you then use to get to the json array
Thanks for the lead :)
