例如，您可以遍历项目，并基于当前游标位置更新其状态(参见清单5)。

For example, you can loop through projects and update their statuses based on the current cursor position (see Listing 5).

youdao

对于行集游标，JDBC 1定位更新语法必须知道行集的存在。

For rowset cursors, the JDBC 1 positioned update syntax needs be aware of the rowset.

youdao

下一步是执行适当的 SQL 查询来构造可更新的游标，方法为根据先前的描述使用 FOR UPDATE 子句。

The next step is to execute the appropriate SQL query to construct your updateable cursor, which requires using the FOR UPDATE clause as described earlier.
