How to set and print the value of json object in postgresql?

Question

What I have done till now is :

DO
$do$
DECLARE
    namz Text;
    jsonObject json = 
            '{
                "Name": "Kshitiz Kala",     
                "Education": "B.Tech", 
                "Skills": ["J2EE", "JDBC", "Html"]
            }';
BEGIN 
    SELECT jsonObject->'Name' into namz;
    select namz;
END
$do$

I am not finding any success here.

actual problem is I am passing a json Object to a stored procedure which will store the data in three different table 1) user table contains user_id, user_name, user_edu. 2) skill table contain skill_id, skill_name. 3) user_skill table contain id, user_id, usr_skill_id.

This is the json object I am passing from Django application

{"Name": "Kshitiz Kala", "Education": "B.Tech", "Skills": ["J2EE", "JDBC", "Html"]}

Your json code is fine, just check:

SELECT '{"Name": "Kshitiz Kala",     
                "Education": "B.Tech", 
                "Skills": ["J2EE", "JDBC", "Html"]
            }'::json->'Name'

or in pgplsql:

DO
$do$
DECLARE
    namz Text;
    jsonObject json = 
            '{
                "Name": "Kshitiz Kala",     
                "Education": "B.Tech", 
                "Skills": ["J2EE", "JDBC", "Html"]
            }';
BEGIN 
    SELECT jsonObject->'Name' into namz;
    raise 'JSON value Name is %', namz;
END
$do$

Problem is somewhere else. Eg. last line in this block won't do anything (SELECT namz in plpgpsql)
