CachedRowSet .. 'populate before calling' 錯誤訊息

故事是這樣的....


使用
CachedRowSet crs=new CachedRowSetImpl();
crs.setPageSize(2);
crs.populate(resultSetObj);
while(crs.nextPage())
{
while(crs.next())
{ //... do something here }
}
竟然出現"'populate before calling' "錯誤訊息,貓的咧,一時間還撒某帳...

原來...
若是使用populate來塞資料給RowSet是無法使用分頁功能的,
原因在於換到下頁時,RowSet無法像是用setCommand去再做一次查詢....

所以說,最好的解決方法就是改用
crs.executeQuery(conn); //conn是自己先前先取得的Connection物件
