DO I need a second Query to do this?


I have a simple CUSTOMER table.
[CustomerID], [CustomerName], [Location]

Location is in the format 99999.
The 3rd digit of the location field is used to JOIN to another table called "LocationDescription".

Question : How can I join the two table together (without using a separate query).  Is it possible?

You can join using WHERE:

    Mid(CustomerTable.Location, 3,1) = LocationDescription.ID

You can do it like this:

SELECT c.CustomerID, c.CustomerName, c.Location, ld.Description
FROM Customer AS c LEFT OUTER JOIN LocationDescription AS ld
ON ld.LocationID=Mid(c.Location, 3,1)

You can also use an INNER JOIN if you'd prefer to only show those records in Customer where a record exists in LocationDescription.

Thanks Scott,

I try that later.
My difficulty was caused because I tend to write my queries using the wizard (rather than pure SQL).
You can use the QBE to create the query and then switch to SQL view to modify the join.  Gus' solution produces a Cartesian Product and so is not updateable.  Scott's solution should be updateable if that is important to you.
