How to use a record variable in the from clausule
I write a SQL function that receives and return a record. I need to use the received record in a from clause. I am using unnest(array[the_variable]).
Is there a specific function or structure to do this? (something like record_to_recordset(the_variable))
Here is my example:
create type calculate_info_type as (super_code text, super_name text);
create function calculate_info(p_country country)
returns calculate_info_type
language SQL as
$SQL$
SELECT super_code, super_name
FROM unnest(array[p_country]), -- <=== HERE!!
lateral (select
prefix is not null as has_prefix
) g1,valores que tenga la tabla
lateral (select
case has_prefix when true then iso||'-'||prefix else iso end as super_code,
case has_prefix when true then name else name||' without phone prefix' end as super_name
) g2
$SQL$;
I put a complete running example here: https://rextester.com/XIRSW33377
