How to return two columns with function

Question

I want to return 2 values with my SQL function:

CREATE OR REPLACE FUNCTION get_avg_prices(...)
  RETURNS table(avg_sale_price decimal, avg_rent_price decimal         


        

Answer 1

Table functions (functions defined as returns table or returns setof) need to be used in the from clause like a table.

So you need to use:

select * 
from get_avg_prices(...);

Only scalar functions (functions which return only a single value, e.g. a number) should be put into the select list.
