I explained that DB2 does not automatically build a result set of all qualified rows at OPEN CURSOR.
我解释过DB 2不能在OPEN CURSOR中为所有符合条件的行自动生成一个结果集。
Then DB2 opens the cursor returns from the procedure and processes the locator allocation to the result set.
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。
将光标置于之间。
A holdable result set permits an application to keep the cursor open after implicit or explicit commits.
可持有结果集允许应用程序在隐式或显式提交之后一直将游标打开着。
Next, set some basic cursor attributes.
接下来,设置一些基本的光标属性。
If the cursor is closed using the close statement before the return of the SQL procedure, the cursor result set will not be returned to the caller or client application.
如果在返回SQL过程之前使用close语句关闭游标,那么游标结果集就不会返回到调用者或客户机应用程序。
You see a new set of tools on the toolbar and a blank screen with a flashing cursor.
可以看到工具条上有一组新的工具,另外还有一个空白的屏幕,其中有一个闪烁的光标。
The find() function actually returns a cursor to the result set of the query, in this case, retrieve all documents.
find()函数实际上向查询结果集返回了一个指针,在本例中是检索所有文件。
The TSQLConnection component is equipped with an ExecuteDirect method to execute an SQL command that doesn't return a result set (also called cursor).
TSQLConnection组件有一个 ExecuteDirect方法,该方法可以执行不返回结果集合的SQL命令(也称为指针)。
It's worth noting that you do not perform the distinct function on a cursor or result set as you do other query functions, but you perform it directly on the collection.
值得注意的是,您在执行其他查询函数时不能在指针和结果集上执行distinct函数,而应直接在集合上执行。
DB2 Connect's optimized network communications infrastructure include the ability to minimize network flows related to cursor (result set) management.
DB 2Connect经过优化的网络通信基础设施具有减少与游标(结果集)管理相关的网络流的能力。
The data is copied by using either INSERT FROM CURSOR, which is the default, or LOAD if the correct option is set.
数据可以通过使用INSERTFROM CURS OR(默认设置)复制,也可以通过LOAD复制(如果设置了正确的选项的话)。
Besides the key combinations shown in Table 3, cursor movement keys such as the right, left, up, and down arrows, and the Home and End keys are usually set to work in a logical way.
除了表3所示的键组合外,鼠标移动键,比如上、下、左、右,以及Home和end键都通常被设置为以逻辑方式工作。
When the FETCH cursor statement fails and does not find another row to retrieve, the value of SQLSUCCESS is set to 0 and the WHILE LOOP ends.
当FETCH游标语句失败并且没有找到另一个要检索的行,SQLSUCCESS的值被设置为 0 并且WHILE LOOP 结束。
There is an extensive set of such "escapes" to move the cursor around a window.
有一组这样的 “转义”可以将光标移动到窗口中的不同位置。
One cursor is required per result set that is to be returned.
每个将要返回的结果集都需要一个游标。
This means that subsequent SQL OPEN and CLOSE operations will merely reposition the cursor to the first row of the result set.
这意味着后续SQLOPEN和CLOSE操作只是将游标重新定位到结果集的第一行。
When you select a set of data from a table or tables in a database, the returned data is known as a cursor.
当您通过数据库的一个或多个表选择一组数据时,返回的数据也称为游标。
In fact, the dimension cursor is similar to an SQL result set with some additional functionality.
实际上,维游标类似于SQL结果集,只是多了一些附加功能。
In this situation, you should add some code to set the cursor focus specifically onto the first editable object on the newly opened window.
这种情况下,应当添加一些代码来专门将光标移到新打开窗口的第一个可编辑对象上。
Walk through the code and place your cursor on the marker bar (along the left edge of the editor area) on the line with the suspected code. Double-click to set the breakpoint.
遍历代码,将鼠标放在可疑代码一行的标记栏(在编辑器区域的左侧)上,双击即可设置断点。
This is indicated by the light bulb when the cursor is set to the field.
当光标进入该字段时,此功能通过电灯泡图标来指示。
A scrollable result set allows the cursor to be moved to any row in the result set.
可滚动结果集允许游标移动到结果集中的任意行。
If you have a long-running OPEN CURSOR, it is not because DB2 is building a result set. It is most likely because DB2 is doing a data sort at OPEN (usually to satisfy a common ORDER BY).
如果您有一个长期运行的OPENCURSOR,并不是因为DB 2正在构建一个结果集,最有可能是因为DB 2正在OPEN(通常满足一个常见orderBY)上进行数据排序。
When a for statement is executed, a cursor is implicitly declared such that for each iteration of the for loop, the next row is the result set if fetched.
在执行for语句时,游标被隐式声明,这样对于FOR循环的每一次迭代,取回的下一行就是结果集。
Or, of course, you can set whatever cursor you need.
或者,当然,你可以设置你需要的任何光标。
The core set of functions include behavior like management of x and y cursor values, word wrap, pagination, and the rendering of text elements.
核心函数集将包括管理x和y 光标值、自动换行、分页及呈现文本元素之类的行为。
Note the code used to put an hourglass cursor on the Workbench window, and the code used to set the status line message. These are not easy to find in PDE documentation or Eclipse.org articles.
注意,用于在Workbench窗口上放置一个沙漏状光标的代码,以及用于设置状态栏消息的代码不易在PDE文档或Eclipse.org文章中找到。
So DB2 needs to dam the result set to ensure that the whole query is finished when the cursor is opened.
因此,DB 2需要dam结果集,以确保当游标被打开时整个查询已经完成。
So DB2 needs to dam the result set to ensure that the whole query is finished when the cursor is opened.
因此,DB 2需要dam结果集,以确保当游标被打开时整个查询已经完成。
