Hi

I have a main table, and i want to make some OUTER LEFT JOIN's at a time
with some other tables.
I know how to make this with 1 table, but not with many tables.
How cai i do this ? (i work with local sql)

Thanks (and sorry for my english)
Paco

From DBDEMOS :

select * from customer
left outer join orders on
customer.custno = orders.custno
left outer join items on
orders.orderno = items.orderno

Keep in mind that a left outer join will retreive all customers in the
customer table, whether they have orders or not, and so on for other tables
joined in the same way. Take a look at all types of joins (full, inner, left
outer and right outer) to decide which one you need.

Here is an example of a local SQL statement using LEFT OUTER joins to
join six of the sample Paradox tables.

  SELECT C.CustNo, O.OrderNo, I.PartNo, P.Description, V.VendorName,
    E.LastName || ", " || E.FirstName AS Agent
  FROM "Customer.db" C
    LEFT OUTER JOIN "Orders.db" O
      ON (C.CustNo = O.CustNo)
    LEFT OUTER JOIN "Items.db" I
      ON (O.OrderNo = I.OrderNo)
    LEFT OUTER JOIN "Parts.db" P
      ON (I.PartNo = P.PartNo)
    LEFT OUTER JOIN "Vendors.db" V
      ON (P.VendorNo = V.VendorNo)
    LEFT OUTER JOIN "Employee.db" E
      ON (O.EmpNo = E.EmpNo)
