TYPE_FORWARD_ONLY结果集的isLast()方法 [英] isLast() method for a TYPE_FORWARD_ONLY result set

问题描述

我一直在尝试寻找一种方法，该方法可以知道我是否位于结果集的最后一行，并且找到了isLast()方法.

I have been trying to search for a way in which I would know if I am on the last row of my result set and I found the isLast() method.

我做了类似的事情:

if(rs.isLast()) {
    //do some operation here
}

但是它给我带来了一个错误:仅向前结果集不支持所请求的操作.

But it game me an error: The requested operation is not supported on forward only result sets.

我搜索了一个解决方案，它说我应该更改TYPE_FORDWARD_ONLY.但是现在，我想知道是否可以使用TYPE_FORWARD_ONLY来让我知道自己是否在最后一个记录集中?

I searched for a solution and it said that I should change the TYPE_FORDWARD_ONLY. But right now, I was wondering if there is a way for me to know if I am in the last record set by using the TYPE_FORWARD_ONLY?

谢谢.

推荐答案

还有一种方法

There is also a methodisAfterLast which you can check after a call to next. This is also not required to be supported for TYPE_FORDWARD_ONLY, but you might try it anyway.
