Hello,

I wish to return the SELECT statement.
Ho can I achieve this?

        DO $$

        DECLARE v_some_id int=14;

        BEGIN
        /*
        more queries here...
        */
        SELECT 'this is text';
        END
        $$ LANGUAGE plpgsql;

Best,

Reinterpreting the question and taking the  pseudocode semi-literally is
the following closer to what was asked?
            ref. 39.2. Structure of PL/pgSQL
            <http://www.postgresql.org/docs/9.2/static/plpgsql-structure.html>

pendari=> CREATE FUNCTION somefunc() RETURNS text AS $$
pendari$>
pendari$> DECLARE
pendari$>   v_some_id int=14;
pendari$> BEGIN
pendari$>   /*
pendari$>     more queries here...
pendari$>   */
pendari$>   RETURN 'this is text'::text;
pendari$> END;
pendari$> $$ LANGUAGE plpgsql;
CREATE FUNCTION
pendari=> select somefunc();
   somefunc
--------------
 this is text
(1 row)

pendari=>
