“从条款”中的错误

Question

我在下面有这个查询。我已经在 ms 访问中检查了它，它工作正常。但是当我将它添加到我的程序时，“FROM 子句中的语法错误”。出现。有关如何解决此问题的任何建议？

String query ="TRANSFORM COUNT(a.present)\n" +
                            "SELECT e.ID,e.firstName,e.lastName,e.position,e.rate\n" +
                            "FROM employees e \n" +
                            "INNER JOIN attendance a \n" +
                            "ON e.ID = a.empID \n" +
                            "GROUP BY e.ID,e.firstName,e.lastName,e.position,e.rate \n" +
                            "PIVOT a.dateAttended";

这是查询所属的完整方法。 connectToDB 方法用于将结果集插入到 jtable 中。 jtables 是否能够插入数据透视查询？

private void attendanceView() throws ClassNotFoundException{
        try{
            String query ="TRANSFORM COUNT(a.present) " +
                          "SELECT e.ID,e.firstName,e.lastName,e.position,e.rate " +
                          "FROM employees e " +
                          "INNER JOIN attendance a " +
                          "ON e.ID = a.empID " +
                          "GROUP BY e.ID,e.firstName,e.lastName,e.position,e.rate " +
                          "PIVOT a.dateAttended";
            Object[][] result = connectToDB(query);
            System.out.print(result);
            monthlyAttendanceTable.setModel(new javax.swing.table.DefaultTableModel(
                    result, new String [] {"Employee ID","First Name","Last Name", "Position", "Rate","",""}
            )
            {
                Class[] types = new Class [] {
                    java.lang.Integer.class, java.lang.String.class, java.lang.String.class, java.lang.String.class, java.lang.Integer.class, java.lang.Integer.class, java.lang.Integer.class, java.lang.Integer.class,java.lang.Integer.class,java.lang.Integer.class,java.lang.String.class
                };
                boolean[] canEdit = new boolean [] {
                    false, false, false, false, false, false, false, false, false,false
                };

                public Class getColumnClass(int columnIndex) {
                    return types [columnIndex];
                }

                public boolean isCellEditable(int rowIndex, int columnIndex) {

                    return canEdit [columnIndex];
                }
            });
        }catch (ClassNotFoundException ex) {
                Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
                ex.printStackTrace();
            } 
    }

试试这个：

将同一个查询拆分成多行时，空格很重要。

String query ="TRANSFORM COUNT(a.present) " +
                            "SELECT e.ID,e.firstName,e.lastName,e.position,e.rate " +
                            "FROM employees e " +
                            "INNER JOIN attendance a " +
                            "ON e.ID = a.empID " +
                            "GROUP BY e.ID,e.firstName,e.lastName,e.position,e.rate " +
                            "PIVOT a.dateAttended";
