Call row_to_json(row) on any PostgreSQL statement (even statements that don't return a result)

Question

I\'m looking for query to always return the JSON representation from PostgreSQL statement, even if there\'s no returning *. Here\'s an example:

WITH         


        

Answer 1

Use returning to get results of insert statement:

with result as (
    insert into users("name", age) 
    values('drew', 42)
    returning *
)
select row_to_json(row) 
from result as row;
