从MS Access中的结果集中插入Excel文件数据

Question

I have a method for checking the attendance of the employees. The firstnames,lastnames, position of employees are retrieve from a database. the daily attendance method works fine. now, I also have a method that creates a monthly attendance report from the daily attendance method. it also retrieves the data in the database. In querying, I used a pivot. It doesn't work. The error says that it has an error in the from clause. but when I test that query in ms access, It works perfectly. Can everyone help me with this. this is my code.

private void attendanceView() throws ClassNotFoundException{
        String query ="TRANSFORM COUNT(attendance.present)SELECT employees.ID,employees.firstName,employees.lastName,employees.position,employees.rate FROM employees LEFT JOIN attendance ON employees.ID = attendance.empID GROUP BY employees.ID,employees.firstName,employees.lastName,employees.position,employees.rate PIVOT attendance.dateAttended";
       Object[][] result = connectToDB(query);
       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];
           }
       });
    }

I've read from some resources that the result set can be inserted to a excel file. Can anyone help me with this? I'm accessing the database through the connectToDB() method, I want to insert to the excel file the pivot query result.

You can use EasyXLS library to export the result set to the Excel file. Check some source code sample here .
