[GENERAL] Use function to manipulate rows — how to get separate columns, rather than single row value
I’m trying to write a function that manipulates whole rows. It returns the same type as the table it is being applied to, but when I select the function on the rows, I get a single column of row type, rather than separate columns.
My function looks like:
CREATE OR REPLACE FUNCTION reporting.formatted_cust_by_state_bold(c reporting_helpers.customers_by_state_ranked)
RETURNS reporting_helpers.customers_by_state_ranked
LANGUAGE plv8
STABLE STRICT COST 1
AS $function$
if (c.rank == 1) {
c['_meta'] = c['meta'] || {}
c['_meta']['raw'] = c['_meta']['raw'] || {}
c['_meta']['raw']['spent'] = c['_meta']['raw']['spent'] || {}
c['_meta']['raw']['spent'] = "<b>" + c.spent + "</b>"
}
return c
$function$
I do this:
SELECT formatted_cust_by_state_bold(c) FROM customers_by_state_ranked c
How do I get the results as a full table?
