FOR read-only cursors, make the cursor unambiguous by using the FOR read only clause.
对于只读游标，使用FORREADONLY子句确保游标无歧义。
This dramatic difference is due to the light-weight forward-only cursor that is the default in PDO.
之所以有这么大的差异，是因为在PD o中默认的游标是轻量级的只能向前移动的游标。
For a fast, forward-only cursor through the results, use an IfxDataReader returned by the ExecuteReader method.
对于快速的、只向前通过结果的游标，可以使用由executereader方法返回的IfxDataReader。
By default, it matches only sequences of "keyword" characters (alphanumerics and underscore), and it has no deep sense of context beyond matching what's immediately to the left of the cursor.
默认情况下，它仅匹配“关键字”字符序列(数字、字母和下划线)，除了与光标左边进行匹配之外，它对上下文没有深刻的理解。
In order to correctly match left and right contexts around the cursor, it needs to ensure the pattern matches only at the cursor's column.
为了正确地在光标周围匹配左边和右边上下文，要确保该模式仅在光标所在的列进行匹配。
This syntax is only valid when the LOAD FROM CURSOR operation is embedded in an ADMIN_CMD call, but it is not valid on the command line.
只有在ADMIN_CMD调用中嵌入LOADFROMCURSOR操作的情况下，这种语法才是有效的，在命令行上是无效的。
With that blinking cursor on our Internet search box only a button away and ever ready to unleash a geyser of electronic information, no longer do we have to go into any encounter wholly unprepared.
互联网搜索中，只要移动光标，鼠标一点，信息就源源不断地出来了。
T2zos does not know if the cursor returned from a stored procedure is rowset or not, thus the t2zos driver allows only single row fetch for a stored procedure.
t2zos不知道从存储过程返回的游标是不是一个行集，因此t2zos驱动程序仅允许对存储过程执行单行获取。
They create a trivial timer event object that contains only an event type -- either timeout or timetick -- and pass it to the same handleEvent method that handles cursor events.
它们仅仅创建一个简单的计时器事件对象，其中只包含一种事件类型 ——timeout或者timetick，并将它传递给处理鼠标事件的同一个 handleEvent方法。
With StAX, parsing an XML document becomes cursor-based, and the application only uses what it needs from the XML document as it progresses.
使用StAX 时，XML文档的解析是基于光标的，应用程序在运行过程中只使用 XML 中需要的内容。
This mouse concept isn't only controls the cursor on the screen, but looks like one, too.
这款鼠标的概念不仅控制屏幕上的光标，本身看上去也是一个光标。
Perhaps the most useful prepared statements are those that not only take input values, but also operate on the current row of a cursor.
或许最有用的准备好的语句不仅可以获取输入值，而且还可以对游标的当前行进行操作。
Note: If you're only going to iterate through a cursor, you can leave the AUTOCOMMIT mode enabled.
注：如果仅通过游标进行循环访问，则可以把AUTOCOMMIT模式保留为启用状态。
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。
I've always thought that READ_COMMITTED (DB2 calls it Cursor Stability (CS)) meant that you do NOT lock on reads, and that you only read the committed data.
我一直认为read_committed (DB 2调用游标稳定性(CS))意味着你不锁上读，那你只能读提交的数据。
There is not much to be said about this query other than the fact that it is the only query that can run with a cursor stability isolation level.
关于这个查询没有很多要讲的，只有一点：该查询是惟一可以以curs or stability隔离级别运行的查询。
The area where my cursor is on image map only those colors should get inverted.
我的光标所在的区域图像映射只有那些颜色应该反转。
The LoadCursor function loads the cursor resource only if it has not been loaded; otherwise, it retrieves the handle to the existing resource.
大致的意思是光标资源只会载入一次，重复的载入返回相同的句柄。
Therefore, the snapshot is only as current as the cursor library's buffer.
因此，快照只与游标库的缓冲区一样新。
While you can change value during the life of the cursor, the change only affects the number of records in the cache after the next fetch from the data source.
虽然您可以在资料指标的存留期间变更值，但变更只会在下一次从资料来源撷取资料录之后，影响快取中的资料录数目。
Keeping the cursor in the sensitive zone (by default 10% width of the display area on the right) you can scroll freely with only the movement of the cursor;
只要鼠标指针在“滚动触发区”（这区域默认是显示面积的右10%）里面，你就能继续自由拖动鼠标指针滚动页面；
The program then enters Eraser mode and on the canvas, the cursor will only erase things until the user chooses another tool.
然后程序就进入了橡皮 擦模态，在选择其他工具之前程序只能擦 除对象。
