SELECT COUNT(*) FROM (SELECT) AS SubQuery works in MS ACCESS but not in JDBC

Pregunta

My query :

SELECT COUNT(*) 
FROM 
   (SELECT 
        dealerCode, 
        SUM(kg) AS totalKG, 
        SUM(price) AS totalPrice, 
        returnDate, BID 
    FROM meatReturns 
    GROUP BY BID, dealerCode, returnDate)

This works well in MS Access Query Design, but it does not work in JDBC.

The query gets a Syntax error in FROM clause in its ResultSet.

Any alternatives, or an explanation to this one?

UPDATE:

Here is my code:

private int getRowCount(String query){
       int size = 0; 
       try {
            query = query.replace(";", "");
            query = "SELECT COUNT(*) FROM (" + query +") AS subQuery;";

            System.out.println(query);

            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                     String db = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=E:/EACA_AgroVentures1.accdb";
                     conn = DriverManager.getConnection(db);
                     stmt = conn.prepareStatement(query,ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);


            ResultSet rs = stmt.executeQuery(); // ERROR HERE
            rs.beforeFirst();
            while(rs.next() && rs!=null){
                size = rs.getInt(1);
                System.out.println("Size : "+size);
            }
        } catch (ClassNotFoundException ex) {
            ex.printStackTrace();
        } catch (SQLException ex) {
            ex.printStackTrace();
        }
       return size;
   }

and here is the ERROR CODE:

Solución

Your problem stems from the fact that

  1. the subquery is an aggregation query (with SUM() functions and a GROUP BY clause) so the result set returned by the Access Database Engine is not updatable, and

  2. in your prepareStatement call you specify ResultSet.TYPE_SCROLL_SENSITIVE.

Those conditions conflict with each other, causing an error. Try this instead:

stmt = conn.prepareStatement(query,
        ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);
ResultSet rs = stmt.executeQuery();
// rs.beforeFirst();  // (disabled)
