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。

您可能认为，针对特定输入，只有方法中的每一行都操作正确，方法才会生成预期结果。
You tend to assume that each line of code in the method must be operating properly in order for the method to produce the expected result, given a certain input.
在导出操作期间，行级别锁定应用于导出表(exportingtable)，这意味着一次只持有一个锁。
During an export operation, row-level locking is applied to the exporting table, which means that only one lock is held at a time.

一旦拥有了一个可以操作行范围的函数调用后，一个特别有用的技巧就是通过Visual模式(参见：help Visual - mode获得更多细节)调用该函数。
Once you have a function call that can operate on a range of lines, a particularly useful technique is to call that function via Visual mode (see: help Visual-mode for details).

In this example, and update occurs if the target and source have matching row.
在决策表中，行和列表示不同的条件，而结果操作由它们的交点来定义。
In decision tables, rows and columns represent different conditions and the resulting action is defined by their intersections.
如果我们希望设计一个提供数据库更新功能的服务，则可以提供与清单8中的第2行和第4行的检索和写入操作对应的操作。
If we wish to design a service offering database update capability, we could offer operations corresponding to the retrieve and write operations in lines 2 and 4 in Listing 8.
这个示例展示，尽管不足以创建一行，但我们必须通过设置操作符(：)来包含它的定义。
This example shows that it is not sufficient to create a row but we have to include its definition through the casting operator (: :).
通过使用这种方法，在对行执行选择、更新或删除操作期间，不会持有行锁。
With this approach, no locks are held between selecting and updating, or deleting a row.
换句话说，我们顺序地扫描了此表，锁定了每个行，操作进行了很多次。
In other words, we have sequentially scanned this table, locking every row, a lot of times.
对于每一个行id,fetch操作符将读取表中相应的行。
For each row ID, the FETCH operator reads the corresponding row from the table.
如果查询中的远程操作在返回行之前需要进行大量的处理，那么就可以获得最大的性能益处。
The benefit is greatest for queries that contain remote operations that require significant processing before they begin to return rows.
然后行id扫描(RIDSCN)操作符将扫描这些行，触发行预取，并将行id传递到fetch操作符。
The row ID scan (RIDSCN) operator then scans these row IDs, triggers row prefetching, and passes the row IDs to the fetch operator.
对于所获取的每一行，XSCAN操作符将处理相应的XML文档。
For each row fetched, the XSCAN operator processes the corresponding XML document.
远程服务器到联邦服务器的行移动及本地HSJOIN操作符与union操作符之间行移动仍然是串行的。
Row movement from the remote servers back to the federated server, as well as between the local HSJOIN operators and the UNION operator is serialized.
注意，可以组合使用多个替换操作符，见脚本的最后一行。
Note that you can combine several substitution operators, as shown in the last line of the script.
可以将当前行想象成一个指针，在这个例子中，该指针固定在接受该操作的行。
The current row can be thought of as a pointer, which in this case is fixed on the row that received the action.
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。
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.
