KPI历史记录请求是异步的；可以在验证数据并完成错误处理后发出事件。
The KPI history requests are asynchronous; an event can be dispatched after you have verified the data and finished the error handling.
通过MapReduce的抽象，google工程师可以简单地进行运算，而不必考虑并行运算的细节、数据的分配、负载平衡和错误处理。
MapReduce is an abstraction that allows Google engineers to perform simple computations while hiding the details of parallelization, data distribution, load balancing and fault tolerance.

The basics of Programming (variables, data types, references, pointers, scope, error handling, iteration, core algorithms - searching, sorting, etc.)
请注意针对后者的错误处理程序可撤销前者所做的工作，以使数据不会处在一种不一致的状态。
Notice that the error handler for the latter undoes the work of the former so that data is not left in an inconsistent state.
在我们的场景中，在执行数据库操作之后，要使用另外两个函数进行错误处理。
In our exercise, you'll be using two more functions to do error processing after a database operation.
在下一篇文章中，我将讨论与错误处理复杂的输入数据相关的错误模式。
In the next article, I will discuss bug patterns related to the mishandling of complex input data.
因为没有错误处理逻辑，必须依靠数据库的限制，以确保数据的语义完整性。
Because there is no error handling logic, you must rely on database constraints to ensure semantic integrity of the data.
此外，它还提供了一些其他的功能，如消息记录、使用数据库中的数据扩充消息、以及根据您的需要定制错误处理。
In addition, it provides functions such as message logging, augmenting messages with data from a database, and error processing that is tailored to your requirements.
首先，整个过程背后的逻辑是合理的：如果您将这项数据元素从可选改为必需，那么您基本上就是复制了系统中其他地方所使用的错误处理过程。
At first, the logic behind this sounds reasonable: If you change this data element from optional to required, you essentially duplicate error processing that occurs elsewhere in the system.
乐观事务锁不能用于在单个update语句中更新数据行集合，因此在这种情况下，很难进行错误处理。
Optimistic transaction locking should not be used to update sets of rows in a single update statement, as error handling in this case is very difficult.
UDP数据包可能会丢失，或者不按顺序发送给接收的应用程序；必须在应用程序层进行错误处理。
UDP Datagrams can be lost or delivered in a different order to the receiving application; the error handling must be done at the application layer as well.
如果要扩展从本文学到的内容，可以通过加入对关系型更新数据源更详细的错误处理来增强小部件。
To try and expand on what you learned from this article, you could enhance the widget with more elaborate failure handling for the relational update feed.
对于这两种平台上的数据库，您都可以声明错误处理程序，如果带有特殊的错误代码(SQLCODE或SQLSTATE)的sql语句失败，那么该处理程序将判定应采取哪些措施。
For both databases you can declare error handlers that will determine what action are taken if an SQL statement fails with a particular error code (SQLCODE or SQLSTATE).
SQLServer 2005Driver forPHPAPI提供了对Windows认证、交易、参数绑定、流、元数据访问和错误处理的支持。
The SQL Server 2005 Driver for PHP API includes support for Windows Authentication, transactions, parameter binding, streaming, metadata access, and error handling.(MSDN)
错误处理损坏的保存数据已被改进。
实用程序的错误处理解决方案已添加。这使您可以读取数据，在UD MA模式情况下，以前的版本可以读取数据仅在PIO模式，。
Utility error processing solution has been added. This enables you to read data within UDMA mode for cases where previous version could read the data only in PIO mode.
错误处理，作为规范的一部分提供，允许出错数据重入，或者跳过出错数据，继续输入过程。
Error handling, provided as part of the input specifications, permits the reentry of bad data, or the continuation of the input process after skipping over the bad data.
为了简洁，不会牵涉到单元测试，输入验证，错误处理，数据封装，审核，路由或任何MVC设计有关的细节。
To keep this demo simple, we will not be covering unit testing, input validation, error handling, data encapsulation, authentication, routing, or any other facets of a well designed MVC application.
使用正确的错误处理，以确保数据库连接总是被关闭(即使是一个错误)，这一点是非常重要的。
Use correct error handling to ensure that the database connectivity always been closed (even when there is a mistake), this point is very important.
