Rows are only locked at the point in time that a cursor is positioned on them; once the next row is fetched, the lock is released.
数据行只是在游标定位它们时才锁定，一旦获取下一行之后，锁将被解除。
The previous example held the database cursor open between user interactions, preventing other users from accessing database segments that are locked.
在前面的示例中，两个用户交互之间将保持数据库游标打开，从而防止其他用户访问被锁定的数据段。
If the selection UI service has a locked selection, or if there is no location property on the control, the default arrow cursor will be set.
如果选择UI服务有锁定的选择，或者如果控件上没有位置属性，将会设置默认箭头游标。
