I try to do a 3-table join in Access and it will not work. Is it possible?
All the various types of multi-table joins that are available in other flavour of SQL are permitted in MS-Access/Jet. For example, here's a straight three-table hierarchical example (a bit more real-world than the other answers here):
SELECT
x.FirstName,
x.Surname,
r.RegionName,
c.CountryName
FROM
(Customer x LEFT JOIN Region r
ON r.ID=x.RegionID)
LEFT JOIN Country c
ON c.ID=r.CountryID
Or did you want to know how to do it using the Visual Designer in MS-Access?
