> I am trying to create a nested json object using JSON_OBJECT and am getting a json with escaped quotes.
>
> I have the following query in sql line :
>
> {code:java}
> select JSON_OBJECT(
> KEY 'level1'
> VALUE(
> JSON_OBJECT(
> KEY 'level2'
> VALUE(
> JSON_OBJECT(
> KEY 'level3'
> VALUE 'val3')
> )
> )
> )
> )
> from (values ('{"a":{"b":2}}')) t(v);
>
> {code}
> And it produces the result:
>
> {noformat}

> {"level1":" {\"level2\":\"{\\\"level3\\\":\\\"val3\\\"}\"}"}
