Join expression not supported - using Access 2000 and CF

<cfquery name="getAll" datasource="#re quest.dsn#">
SELECT U.userID, U.fname, U.lname, U.phone, U.lastLoggedIn,
U.choiceId, U.experience, T.label AS teamLabel, R.label AS
roleLabel
FROM User U LEFT JOIN UserTeamAssoc UTA
ON UTA.userID = U.userID,
Role R, UserRoleAssoc URA, Team T
WHERE U.userID = URA.userID
AND URA.roleID = R.roleID
AND U.userId > 1
ORDER BY #orderBy# #orderByTxt#
</cfquery>

This query produces the following error:

Join expression not supported.

Has anyone else run into this problem, if so, what can I do about it? I do
not have the ability to install Access on my machine so any solution could
not involve working with Access itself (I do have the .mdb file that I use
via ColdFusion App Server)

It looks pretty good to me - although I always list my non
outer joined tables in the from clause first - ie:

FROM Role R, UserRoleAssoc URA, Team T, User U
LEFT JOIN UserTeamAssoc UTA
ON UTA.userID = U.userID

I dunno if that matters though...

The guy I work with just muttered something to me about
sometimes needing to surround join clauses in access with
curly braces. You might want to try looking into that.

This might help, this is how I'd write it in Oracle:

<cfquery name="getAll" datasource="#re quest.dsn#">
SELECT U.userID, U.fname, U.lname, U.phone, U.lastLoggedIn,
U.choiceId, U.experience, R.label AS roleLabel
FROM Role R, UserRoleAssoc URA, Team T, User U, UserTeamAssoc UTA
WHERE U.userId = URA.userID
AND URA.roleId = R.roleId
AND U.userId = UTA.userID (+)
AND T.teamId = UTA.teamID (+)
AND U.userID > 1
ORDER BY #orderBy# #orderByTxt#
</cfquery>

Try something along the lines of:
<cfquery name="getAll" datasource="#re quest.dsn#">
SELECT U.userID, U.fname, U.lname, U.phone,
U.lastLoggedIn,
U.choiceId, U.experience, R.label AS
roleLabel
FROM Role R, UserRoleAssoc URA, Team T, User U
{oj LEFT OUTER JOIN UserTeamAssoc UTA ON UTA.userID
= U.userID}
ORDER BY #orderBy# #orderByTxt#
</cfquery>

I'll stop guessing now if someone has the proper answer...

Phil,

I see you don't have a join-clause for the Team-table (T).
Is the cartesian product the intention ?
If used an outer join clause, Jet probably doesn't know how to join
the Team table to this .. (the left or right side ?) Access would have
complained 'ambiguous outer join'.
I think either use an inner join in stead of left outer join +
cartesian product with Team or add a join expression for Team.
In general Access prefers explicit join-statements in stead of
implicit ones. For updatability of a query the explicit
join-statements are often one of the conditions.

Phil,

Sorry, I forgot to mention another 3rd option, namely to split off the
left-outer join of the 2 tables and to put it in a seperate stored
query and to use that query as a table togeter with the other tables
in an inner-join or cartesian product with the Team table.

First you have no relation set from UTA to T. I've added what I
think you want
Second Access wants inner joins so marked, otherwise it produces
huge recordsets and then filters them through the where clause..

try:
From ((((User U INNER JOIN UserRoleAssoc URA
on U.userID = URA.userID)
INNER JOIN role R
on URA.roleID = R.roleID)
(LEFT JOIN UserTeamAssoc UTA
ON UTA.userID = U.userID
INNER JOIN team t
on T.teamID = UTA.teamID))

You may remove the now unnecessary where clauses.

If you get an error message try converting the last inner join to a
left join. Acess is sometimes picky about mixing inner and outer
joins.

I've created an ASP application which uses an Access database. I've created an outer join query, but for some reason the "Property_Def" column is not aligning with the "ESPN" column. They should be aligned on the ESPI common columns. In this attached image, the first lines ESPI of 010471 "ADJUSTABILITY" which should line up with the "Property_Def" column that says "An indication of whether or not the item is adjustable".
