Suppose this is my hive table

A B C
a1 {'age':0,'name':b1, 'id':100} c1
a2 {'age':1,'name':b2, 'id':200} c2
a3 {'age':2,'name':b3, 'id':300} c3
How to select only this
age name
0 b1
1 b2
2 b3
using SQL query on hash table

To get the result you wanted you can use the following query:

SELECT get_json_object(B,'$.age')  as age,
       get_json_object(B,'$.name') as name
FROM table_name

Where B is your column name
