Java JDBC-ODBC GROUP BY (aggregate function) error

Question

I get the error
"java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] You tried to execute a query that does not include the specified expression 'CUSTOMER_ID' as part of an aggregate function."
when I try to execute the following query:
PreparedStatement stmt = connection.prepareStatement(
"SELECT Customers.customer_id, Customers.customer_name, SUM(Transactions.surcharge) AS surcharge, SUM(Transactions.interchange) AS interchange, SUM(Transactions.approved) AS transactions " +
"FROM (Customers INNER JOIN Terminals ON Customers.customer_id = Terminals.customer_id) " +
"INNER JOIN Transactions ON Terminals.terminal_id = Transactions.terminal_id " +
"WHERE Transactions.transaction_date=#12/8/2003# " +
"GROUP BY Customers.customer_id, Customers.customer_name",
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY
Funny thing is this query works fine when I execute it in Microsoft Access directly. I can't figure out what's causing the problem. Any help?

Answer 1

Have you tried:
PreparedStatement stmt = connection.prepareStatement(
"SELECT Customers.customer_id, Customers.customer_name, SUM(Transactions.surcharge) AS surcharge, SUM(Transactions.interchange) AS interchange, SUM(Transactions.approved) AS transactions " +
"FROM (Customers INNER JOIN Terminals ON Customers.customer_id = Terminals.customer_id) " +
"INNER JOIN Transactions ON Terminals.terminal_id = Transactions.terminal_id " +
"WHERE Transactions.transaction_date=#12/8/2003# " +
"GROUP BY customer_id, customer_name",
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY
(Who knows ?... Sometimes SQL engines are very strangely built!)
