postgresql jsonb parses attributes, queries and sorts them;
1. Example of other_name field
[{
"title": "BQ Product", "value": "aValue"}, {
"title": "CTB Product", "value": "bValue"}]
2. Inquiry
select (other_name->0) from dim_product_mapping
select (other_name->0)::jsonb->'title' from dim_product_mapping
select (other_name->0)::jsonb->'value' from dim_product_mapping
3. Sorting
select * from dim_product_mapping where 1=1 order by (other_name->0)::jsonb->'value',update_time desc limit 12 offset 0
Note: it is jsonb, not json
