This works, but surely there is a better way to do it:

                                                           into json_table2;

It sorts the json_table2 array in "portal_name" order. 

I'm confused why you can't just pull portal_name from the json structure using "->"? For example, assuming your json structure that looks like:

{"portal_name": "some data.."}

And a table that looks like:

| id | json_field |

Wouldn't this sql work:

select * from json_table

order by json_field->'portal_name'
