Flatten a JSONB file - What function/query

Question

In a bit of a pickle at work - I have a Jsonb which I need to flatten a file that has similar structure:

{
   "Manufacturers":[
      {
         "manufacturer":"Tesla",
         "address":"Deer Creek Road Palo Alto",
         "contact":"support@tesla.com"
      },
      {
         "manufacturer":"BMW",
         "address":"Petuelring 130, 80809 München",
         "contact":"support@bmw.com"
      }
   ]

I want this in a table format where manufacturing are column names! Something like this - Postgres JSONB - Flatten nested objects and groupings! Can't seem to understand how to get there. He has mentioned using jsonb_to_recordset but not sure how to get everything in a typical csv format.

Example of how I want to see the data -

Answer 1

You can indeed use jsonb_to_recordset, but you also need to use -> to pull out the manufacturer property.

Your expected result is unclear, but it looks like you could do this:

SELECT j.*
FROM YourTable t
CROSS JOIN jsonb_to_recordset(t.jsonColumn->'manufacturer')
    AS j(manufacturer varchar(100), address varchar(100), contact varchar(100));
