postgresql jsonb解析属性

postgresql jsonb解析属性，并查询、排序；

1. other_name字段示例

[{
    
    "title": "BQ Product", "value": "aValue"}, {
    
    "title": "CTB Product", "value": "bValue"}]

2. 查询

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. 排序

select * from dim_product_mapping where 1=1  order by (other_name->0)::jsonb->'value',update_time desc limit 12 offset 0

注意：是jsonb,不是json
