带有输出参数

Question

所以我有以下存储过程来创建一个站点。我希望我的ruby代码返回ourput参数。我需要更改什么才能使其正常工作？

-- FUNCTION: public.createsite(text, boolean, bigint, text, integer, text)

-- DROP FUNCTION public.createsite(text, boolean, bigint, text, integer, text);

CREATE OR REPLACE FUNCTION public.createsite(
    sitename text,
    activeflag boolean,
    createdby bigint,
    sitedba text DEFAULT NULL::text,
    facilityid integer DEFAULT NULL::integer,
    siltelogo text DEFAULT NULL::text,
    OUT siteid bigint)
    RETURNS bigint
    LANGUAGE 'plpgsql'
    COST 100.0
    VOLATILE 
AS $function$

    BEGIN

        INSERT INTO public.SITES(
            SITE_NAME, SITE_DBA, ACTIVE_FLAG, FACILITY_ID, 
            SITE_LOGO, CREATED_BY, MODIFIED_BY,
            created_at, updated_at)
        VALUES (SiteName, SiteDBA, ActiveFlag, FacilityID, SilteLogo, CreatedBy, CreatedBy, 'now', 'now')
        RETURNING SITE_ID
        INTO SiteID;
    END;

$function$;

ALTER FUNCTION public.createsite(text, boolean, bigint, text, integer, text)
    OWNER TO owner_name;

如何在ruby代码中返回输出参数？

post 'new' do
      begin
        v1 = "site name"
        v2 = "flag"
        v3 = "1"
        v4 = "dba"
        v5 = "1"
        v6 = "logo

        sp_String = "select createsite('#{v1}', '#{v2}', '#{v3}', '#{v4}', '#{v5}','#{v6}')"
        #puts s_pString

        results =  ActiveRecord::Base.connection.execute(s_pString)

        return results
      end
    end
