    String cmpId = ""; 
//fetching ids from this table one by one and passing id to another table 
    Cursor preAppointmentRecord = JasperDatabase.getInstance(PreAppointmentsActivity.this).getPreAppointmentRecord(); 
    preAppointmentRecord.moveToFirst(); 
    if (preAppointmentRecord.getCount() != 0) { 
     while (!preAppointmentRecord.isAfterLast()) { 
      cmpId = preAppointmentRecord.getString(1); 
      getAllCompanyName(cmpId); 
      preAppointmentRecord.moveToNext(); 
     } 

     preAppointmentRecord.close(); 

    } 
} 
private void getAllCompanyName(String companyId) { 
    //fetching company names with matched ids 
    Cursor companyNameCursor = JasperDatabase.getInstance(PreAppointmentsActivity.this).getPreAppointmentCompanies(companyId); 
    companyNameCursor.moveToFirst(); 
    if (companyNameCursor.getCount() != 0) { 
     while (!companyNameCursor.isAfterLast()) { 
//getting second string from database     
recordsAr.add(new PreAppointmentRecord(companyNameCursor.getString(2))); 
      companyNameCursor.moveToNext(); 
     } 
     companyNameCursor.close(); 
    } 
}
