1·Updatable cursors (through JDBC).

可更新的游标(通过JDBC)。

2·Open the cursors to be returned.

打开将被返回的游标。

3·The AIM Research Group has developed two cursors.

AIM研究小组已经开发了两种光标。

4·There is no MRF support for forward only cursors.

还没有针对单进游标的 MRF 支持。

5·Listing 4 shows a simple example of how XML cursors work.

清单4是一个简单的例子，说明了XML游标的用法。

6·XQuery queries can only be run as part of dynamic cursors.

XQuery查询只能作为动态游标的一部分运行。

7·This means the database server has run out of dynamic cursors.

这意味着数据库服务器已用尽动态游标。

8·Oracle cursors can be declared, opened, fetched from, and closed.

Oracle游标可以被声明、打开、取数据和关闭。

9·T4 and T2u may elect to use MRF for forward only cursors in the future.

在未来，T4和T2u可能选择仅对单进游标使用MRF。

10·We will see more about using cursors and queries to filter data next.

接下来我们将了解更多有关使用指针和查询来筛选数据的方法。

游标

1·There are no differences in the declarations of local variables, cursors, temporary tables, but on both platforms the order of declaration is important.

在局部变量、游标和临时表的声明方面，两种平台没什么差别，但在这两种平台上，声明的顺序却很重要。

2·Because these resources, like the connection or any database cursors, can be managed outside the JVM running your database application code, your application must close them explicitly.

因为可以在运行数据库应用程序代码的JVM之外管理连接或数据库游标这样的资源，所以应用程序必须显式地关闭这些资源。

3·In contrast, IDS SPL supports a similar cursor looping statement but does not allow cursors to be explicitly declared, opened, or closed.

相反，虽然IDS SPL也支持类似的游标循环语句，但是不允许显式地声明、打开或关闭游标。

4·This means the database server has run out of dynamic cursors.

这意味着数据库服务器已用尽动态游标。

5·However, in some cases, you will need to read cursors both forward and backward, in which case you should use scrollable cursor.

但某些情况下，您需要游标既能向前又能向后，此时需要使用可滚动游标。

光标

1·With no escape sequences to move cursors, change foreground and background colors, set blinking or inverse, etc., we are back to Teletypewriters and other mechanical AIDS.

没有转义字符移动光标、改变前景和背景色、设置闪屏或反向等等，我们将回到电传打字机和其它机械辅助的时代。

2·Now, researchers at the University of Washington have developed new cursors that make activating objects easier for people with motor disabilities.

现在，华盛顿大学的研究人员研发了一种新的光标，这将让存在运动障碍的人更容易激活对象。

3·The AIM Research Group has developed two cursors.

AIM研究小组已经开发了两种光标。

4·The important point here is that you can choose to define indexes as DPSIs without losing that index's aptitude for sort avoidance, including the sort avoidance required for DYNAMIC SCROLL cursors.

这里的重点是您可以选择在不丢失索引功能的前提下将索引定义为 DPSI 来规避排序，包括 DYNAMIC SCROLL 光标所需的规避排序。

5·Because asynchronous transactions are used in Lite mode, you won't be delayed by wait cursors as you open documents and scroll through views.

因为在Lite模式中使用异步事务，因此在打开文档或滚动视图时，不会因等待光标而延迟。

(1)cursor position光标位置

(1)cursor movement光标移动
