the code don't make it work
i need to show the salesname,and the field 'salesname' is on Person Table same like 'customername' it's on 1 field

it's look like this
Table Invoice = Invoice.SalesID and Invoice.CustomerID

Table Person= Person.PersonID,Person.PersonName,Person.PersonTip e

so first i must join the invoice with person table with Invoice.CustomerID=Person.PersonID

but how to join them again with
Invoice.SalesID=Person.PersonID


thx

you only mentioned 2 tables on your first post. on your latest reply, it looks like it's coming from four tables. would you mind posting the name and structure of all the four tables? and how you would like them joined?

try:

select INVNO, CustomerTable.Name as CustomerName, SalesTable.Name as SalesManName
from INVOICE
inner join 
(select IDPERSON, TYPE, NAME from TablePerson where TYPE = 'CUSTOMER') CustomerTable on CustomerTable.IDPERSON = INVOICE.IDCUSTOMER
inner join
(select IDPERSON, TYPE, NAME from TablePerson where TYPE = 'SALES') SalesTable on SalesTable.IDPERSON = INVOICE.IDSALES

the query assumes all IDs in invoice table are in person table. if there are IDs in invoice table that are not in persons table, change INNER to LEFT OUTER

try enclosing the TYPE field with hard brackets...make it [TYPE]....i think it's a reserve word...if you run that query only, does it run? what's the actual error?

I am assuming that the PK of the Person table is ID (and not ID, Type)

Select 
    i.INVNO,
    c.ID,
    c.Name,
    s.ID,
    s.Name
From Invoice i 
Inner Join Person c
    On i.IDCUSTOMER = c.ID
Inner Join Person s
    On i.IDSALES = s.ID

it looks like my query will not work with kind of sql server. but i think Graham's will....

and just in case PK is ID, TYPE....try:


Select
i.INVNO,
c.ID,
c.Name,
s.ID,
s.Name
From Invoice i
Inner Join Person c
On i.IDCUSTOMER = c.ID and c.TYPE = 'CUSTOMER'
Inner Join Person s
On i.IDSALES = s.ID and s.TYPE = 'SALES'
