Помогите написать выборку.

Приветствую.

Есть несколько таблиц. Мне нужно написать выборку чтобы вместо request_type_id и прочих _id подставлялись
текстовые значения из соотв. таблиц. Один JOIN я ещё написать могу, а с остальными теряюсь.

drupal6=# \d journal_of_requests
Table "public.journal_of_requests"
Column | Type | Modifiers
-------------------+-----------------------------+-------------------------------------------------------------------
rid | integer | not null default nextval('journal_of_requests_rid_seq'::regclass)
request_date | timestamp without time zone | not null default now()
request_type_id | integer | default 0
request_object_id | integer | default 0
request_org | character varying(255) | default ''::character varying
request_person | character varying(255) | default ''::character varying
request_phone | character varying(255) | default ''::character varying
request_point | character varying(255) | default ''::character varying
request_state_id | integer | default 0
request_comment | character varying(255) | default ''::character varying
request_executive | character varying(255) |
Indexes:
"journal_of_requests_pkey" PRIMARY KEY, btree (rid)
"journal_of_requests_rid_idx" btree (rid)
Check constraints:
"journal_of_requests_request_object_id_check" CHECK (request_object_id >= 0)
"journal_of_requests_request_state_id_check" CHECK (request_state_id >= 0)
"journal_of_requests_request_type_id_check" CHECK (request_type_id >= 0)
"journal_of_requests_rid_check" CHECK (rid >= 0)

drupal6=# \d request_object
Table "public.request_object"
Column | Type | Modifiers
----------+------------------------+--------------------------------------------------------------
oid | integer | not null default nextval('request_object_oid_seq'::regclass)
obj_name | character varying(255) | not null

"request_object_oid_idx" btree (oid)
Check constraints:

drupal6=# \d request_state
Table "public.request_state"
Column | Type | Modifiers
------------+------------------------+-------------------------------------------------------------
sid | integer | not null default nextval('request_state_sid_seq'::regclass)
state_name | character varying(255) | not null
Indexes:
"request_state_pkey" PRIMARY KEY, btree (sid)
"request_state_sid_idx" btree (sid)
Check constraints:

drupal6=# \d request_type
Table "public.request_type"
Column | Type | Modifiers
--------+------------------------+-------------------------------------------------------------
rtid | integer | not null default nextval('request_type_rtid_seq'::regclass)
type | character varying(255) | not null
Indexes:
"request_type_pkey" PRIMARY KEY, btree (rtid)
"request_type_rtid_idx" btree (rtid)
Check constraints:
"request_type_rtid_check" CHECK (rtid >= 0)
