当您在游标内找到了所需行后，您可以执行相应的UPDATE操作。

When you 've found the desired row within your cursor , you can issue the appropriate UPDATE operation .

通过关联（correlation），SQL表函数允许以一种更高效的方式实现迭代，而不是使用游标。

Through correlation , SQL table functions allow a more efficient way of implementing iterations , otherwise done with cursors .

可以使用StatisticDetails等监视面板上的历史游标访问短期历史数据。

Short-term history data can be accessed using the history slider on the monitoring panels , such as Statistic Details .

还应注意的是，在顶部没有SORT，因为该语句是一种SELECTINTO，而不是游标。

Also note that there is no SORT at the top because the statement is a SELECT INTO rather than a cursor .

Oracle游标的使用方法

The use of the cursor in Oracle

ALTERTABLE等一些操作要求不打开游标，而CREATEINDEXONLINE等其它操作则允许表上的游标。

Some operations like ALTER TABLE require no cursor to be open , while others like CREATE INDEX ONLINE allow cursors on the table .

在DB2中，要想让游标在提交之后仍然打开，应该把它们声明为WITHHOLD游标。

In order to keep the cursor open after commit , they should be declared as WITH HOLD cursors in DB2 .

然后，DB2打开从过程中返回的游标，并处理分配给结果集的定位器。

Then DB2 opens the cursor returns from the procedure and processes the locator allocation to the result set .

不需要通过执行DECLARECURSOR单独定义所需的游标。

Definition of the required cursor does not occur separately by executing DECLARE CURSOR .

另外，还可以在shell命令前面加上从当前游标位置开始希望操作的行数。

Alternatively , you can prefix the shell command with the number of lines you want it to operate on from the current cursor .

产生这种性能问题的原因是，统一ODBC使用可滚动的键集驱动游标来发出SELECT语句。

The reason for this performance issue is that Unified ODBC uses scrollable dynamic cursors to issue SELECT statements .
