I've taken on the unfortunate task of updating an existing query to
include another table in a left join. unfortunately, I'm getting this
error:

Join Expression Not supported

When I try to run the query with the Left Join section in there. I'm
using Access 97 ( I know... blah ). I remove the join and it works.
The fields are correct, ive played with this thing for a while now with
absolutely no success. Any ideas?

SELECT distinctrow OrderMaster.OMSchoolID,
OrderMaster.OMTeacherID, OrderMaster.Date,
OrderMaster.Date, OrderDetail.ODOrderID, OrderDetail.ODShowID,
Schools.Name, Schools.Address1, Schools.Address2,
Schools.City, Schools.State, Schools.Zip,
[FName] & " " & [LName] AS TName,
Teachers.FName,
Teachers.LName, Shows.Date, Shows.Time, Shows.Desc,
OrderDetail.Status,
OrderStatusCodes.Desc,
OrderStatusCodes.Inventory,
OrderStatusCodes.Due,
OrderDetail.Qty, OrderDetail.Type,
SeatTypes.Desc, SeatTypes.Normal, SeatTypes.Due,
Shows.Price, [SeatTypes].[Due]*[OrderStatusCodes].[Due] AS Mult,
[Qty]*[Price]*[Mult] AS Expr1, [Expr1]+[Fees]*[Mult] AS Expr3,
OrderDetail.Date,
OrderDetail.[Study Guides], OrderDetail.Fees, Schools.Phone1,
OrderDetail.Workshops

FROM

Teachers, Schools, OrderMaster, Shows, SeatTypes,
OrderStatusCodes, OrderDetail

LEFT JOIN AR ON OrderDetail.ODShowID = AR.ARShowID
AND OrderDetail.ODOrderID = AR.AROrderID


WHERE
OrderMaster.Date >= [Begin Date?] And OrderMaster.Date <= [End Date?]
AND SeatTypes.StypeID = OrderDetail.Type AND
Shows.ShowID = OrderDetail.ODShowID AND
OrderMaster.OrderID = OrderDetail.ODOrderID AND
Schools.SchoolID = OrderMaster.OMSchoolID AND
Teachers.TeacherID = OrderMaster.OMTeacherID AND
OrderStatusCodes.StatusID = OrderDetail.Status


ORDER BY OrderDetail.ODOrderID DESC , Shows.Date, Shows.Time,
Shows.Desc, OrderDetail.Type;

Hi,



First, make a query just involving AR and OrderDetail

SELECT OrderDetail.*, Ar.*
FROM OrderDetail LEFT JOIN AR
ON OrderDetail.ODShowID = AR.ARShowID
AND OrderDetail.ODOrderID = AR.AROrderID


Save it, as Qu1.


Next, just use

SELECT ...
FROM othertables, Qu1




Hoping it may help,

I'm curious: do you *really* want a Cartesian join, showing every
possible combination of all Teachers, all Schools, all OrderMasters,
etc. etc.? Won't that give you an enormous recordset with a great many
irrelevant records (i.e. a Teacher joined to a School other than the
teacher's own school, or OrderDetail records displayed with completely
different OrderMaster records)?

If that *is* what you want Michel's suggestion should work... but this
seems a very odd query!
 
Check out the where clause in the original query. I rewrote the entire
query to be more readable to me when I couldn't get it to work using
INNER JOINS like Access sets up.

oops! Sorry. Haven't used WHERE clause joins since working in Oracle
ten or twelve years back.
