"Join Expression Not Supported" - Need help on Microsoft Access Query - sql

Question

I need some help making the following SQL code work:
SELECT MemberData.MemberID, Transaction.TrxID, Transaction.Date,
Transaction.GroupID, TransactionDetails.CashIn, TransactionDetails.CashOut
FROM [Transaction]
INNER JOIN (MemberData LEFT JOIN TransactionDetails
ON MemberData.[MemberID] = TransactionDetails.[MemberID])
ON Transaction.[TrxID] = TransactionDetails.[TrxID];
An error stating below keeps popping up:
Join Expression Not Supported"
What am I doing wrong and how can I fix this?

Answer 1

I can't pinpoint the exact source of the error, but a simple fix for most of the Join expression not supported errors is to do one join at a time, and use subqueries.
SELECT MemberData.MemberID, T.TrxID, T.[Date],
T.GroupID, T.CashIn, T.CashOut
FROM (
SELECT [Transaction].TrxID, [Transaction].Date, [Transaction].GroupID, TransactionDetails.CashIn, TransactionDetails.CashOut, TransactionDetails.[MemberID]
FROM [Transaction]
LEFT JOIN TransactionDetails ON [Transaction].[TrxID] = TransactionDetails.[TrxID]
) AS T
INNER JOIN MemberData ON MemberData.[MemberID] = T.[MemberID];

#Poomind #Erik von Asmuth Just change the INNER JOIN into RIGHT JOIN You could try pasting the next SQL-statement into a new query.
SELECT MemberData.MemberID, T.TrxID, T.[Date], T.GroupID, T.CashIn, T.CashOut
FROM (SELECT [Transaction].TrxID, [Transaction].Date, [Transaction].GroupID,
TransactionDetails.CashIn, TransactionDetails.CashOut, TransactionDetails.[MemberID]
FROM [Transaction]
LEFT JOIN TransactionDetails ON [Transaction].[TrxID] = TransactionDetails.[TrxID])
AS T RIGHT JOIN MemberData ON MemberData.[MemberID] = T.[MemberID];
When I saved this query in a sample database, ms-access (version 2003) changed it to the following SQL-statement. So, don't worry if this happens with you too.
SELECT MemberData.MemberID, T.TrxID, T.[Date], T.GroupID, T.CashIn, T.CashOut
FROM [SELECT [Transaction].TrxID, [Transaction].Date, [Transaction].GroupID, TransactionDetails.CashIn, TransactionDetails.CashOut, TransactionDetails.[MemberID]
FROM [Transaction]
LEFT JOIN TransactionDetails ON [Transaction].[TrxID] = TransactionDetails.[TrxID]
]. AS T RIGHT JOIN MemberData ON MemberData.[MemberID] = T.[MemberID];
