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。
For MDC tables, the selection of BLOCKINSERT may improve the performance of INSERT operations by locking at the block level and avoiding row locks for INSERT operations.
对于mdc表，选择BLOCKINSERT可以提高INSERT操作的性能，因为使用的是块级的锁，避免了为INSERT操作使用行锁。
This function is used in select operations to retrieve the row security label column.
该函数在选择操作中检索行安全标签列。
Because the SELECT INTO returns a single row it cannot be used for other RPG read operations.
由于SELECTINTO返回单个行，因此它不能用于其他R PG读操作。
One thing that can be confusing about R's "everything is a vector" approach is that row-wise and column-wise operations may not adhere to your intuition.
关于R的 “所有东西都是向量”方式，容易引起混乱的一点是行操作和列操作可能不符合直觉。
In this case, we will follow the Active Record pattern and wrap a database row with a class capable of all database operations. Its code is shown below.
在本例中，我们将遵循activeRecord模式并用能够执行所有数据库操作的类封装数据库行。
A detail JSP and corresponding Pagehandler functions for displaying the details of a specific database row (add, update, and delete operations can also be performed through the detail pages).
一个详细的JSP和相应的Page handler显示一个特定数据库行的细节的功能(添加、更新和删除操作也可以通过这些细节页执行)。
For example, OLTP-like applications would typically benefit from smaller pages sizes since operations tend to be quick updates a single row retrievals.
例如，诸如oltp的应用程序一般受益于较小的页面大小，因为操作趋向于为快速更新单行检索。
In addition, if the remote operations take approximately the same amount of time to return the first row, then the benefit achieved in enabling asynchrony is maximized.
此外，如果远程查询都是执行大约相同一段时间之后返回第一行数据，那么异步带来的好处就可以实现最大化。
Similarly, during merge-update and merge-delete operations, only for-each-row update or for-each-row delete triggers on the target table are activated.
类似地，在merge -update和merge -delete操作过程中，仅激活目标表上的for - each -row update或者for - each - row delete触发器。
