if i understand your problem right, you could use a View type as return type ... in this view you declare the fields you want to return ...

Hello,
I would like to know how to recuperate the results of a request.
I read the O'Reilly book about Postgresql and and know there are 2 ways in PL/pgSQL to do that :
1. declare variable type; select into variable column for table where...
2. declare variable table%ROWTYPE for variable in select * from table where...
What I want to do is to make a multitable request and to recuperate each line of the result by stocking a number or text into variable
eg with int; declare sum int := 0; for variable in select count(distinct sold), name from books natural join authors... loop sum = sum + sum; ...
eg with text declare list text := '''': variable as text; for variable in select title from books natural join authors... loop if variable like ''The%'' list := list || variable.title || ''\n'' ...
Thanks.
