hi all
i was wonder if its possible to join 3 tables, so i could see the result from the 3 tables.
for example
lets say that i have
INVOICE(invoice_id, client_id,item_id)
CLIENTS(id, client_name)
ITEM(item_id, item_name)
i want 1 table that shows: invoice_id, client_name,item_name
is this possible?

How your tables are linked to each other ?

I don't think they are.

I don't think they are.

INVOICE(invoice_id, client_id,item_id)
CLIENTS(id, client_name)
ITEM(item_id, item_name)

I think he/she will have to client_id with id on client and Invoice then union on ITEM.item_ID = INVOICE.Item_ID

if it wasn't clear
INVOICE(invoice_id, client_id,item_id)
CLIENTS(client_id, client_name)
ITEM(item_id, item_name)

client_id in invoice is FK IN CLIENTS
item_id in INVOICE is FK in ITEMS
so they are linked

oh, and union will not work because union returns one field, not multiple fields

THANKS FINITO
you're link was very helpful!
this is the code of joining 4 tables for any one here who might want to know the answer:

select invoice_title.id, clients.name,items.item_des, invoice_line.amount
from invoice_title, clients, invoice_line,items
where invoice_title.client_id=client_id and invoice_line.item_id=items.item_id and
invoice_title.id=invoice_line.id  order by item_des;

INVOICE(invoice_id, client_id,item_id)
CLIENTS(id, client_name)
ITEM(item_id, item_name)
i want 1 table that shows: invoice_id, client_name,item_name

select i.invoice_id ,c.client_name,it.item_name
from invoice i, client_name c,item_name it
where (i.client_id = c.client_id) AND (i.item_id = it.item_id)

select i.invoice_id ,c.client_name,it.item_name
from invoice i, client_name c,item_name it
where (i.client_id = c.client_id) AND (i.item_id = it.item_id)

i assumed tables are joined according to id's.
u try this query and reply me if done

>>create table abc(invoice_id,client_name,item_nane)
as select i.invoice_id,c.client_name,it.item_name
from invoice i,client c,item it
where
i.item_id = it.item_id and
i.client_id = c.client_id;
