When actions fail , error messages include a " show technical details " button , which presents detailed information from all application and programming levels 当操作失败时，错误消息包括一个“显示详细的技术信息”按钮，这可以提供来自所有应用程序和编程级别的详细信息。
If your data source supports transactions , you should include each add operation in a transaction and roll back the transaction and throw an exception if any add operation fails 如果数据源支持事务，则应在事务中包含每个添加操作，并且如果添加操作失败，则应回滚事务并引发异常。
If your data source supports transactions , you should include each remove operation in a transaction and roll back the transaction and throw an exception if any remove operation fails 如果数据源支持事务，则应在事务中包含每个删除操作，并且如果删除操作失败，则应回滚事务并引发异常。
Duplicate names resulting from the new collation will cause the change action to fail , and sql server will return an error message specifying the namespace where the duplicate was found 由新的排序规则产生的重复名称将导致更改操作失败， sql server将返回错误消息，指出重复名称所在的命名空间。
If your data source supports transactions , it is recommended that you include all delete operations in a transaction and roll back the transaction and throw an exception if any delete operation fails 如果数据源支持事务，建议将所有删除操作包括在事务中，并且如果任何删除操作失败，您可以回滚事务并引发异常。
If the update failed and the transaction rolled back , another message could be sent to the jms provider on a separate destination , describing the reason for the failed transaction 如果更新操作失败并且事务回滚（ rollback ） ，则再发送一条消息到一个单独的目的地上的jms提供者那里，同时给出对事务失败的原因的描述。
If your data source supports transactions , it is recommended that you include all delete operations in a transaction and that you roll back the transaction and throw an exception if any delete operation fails 如果数据源支持事务，建议将所有删除操作包括在事务中，并且如果任何删除操作失败，您可以回滚事务并引发异常。
For example , if a sequence container includes two related tasks , one task that deletes data in a table and another task that inserts data into a table , you can configure a transaction to ensure that the delete action is rolled back if the insert action fails 例如，如果序列容器包含两个相关任务（一个任务删除表中的数据，另一个将数据插入到表中） ，则可配置事务以确保插入操作失败时回滚删除操作。
Once a client - server pair experiences an interoperability failure on one or all of the tests , the problem is usually reported on the list and the community has the chance to immediately discuss why the failure occurred and what might be done to correct it 一旦一对客户机服务器在一个（或者全部）测试中进行交互操作失败，这一问题通常会在列表中公布出来，这样实现者社区就有机会立即探讨失败的原因以及应该怎样纠正错误。
By using message queues to store pending confirmation e - mails , inventory checks , or credit checks , you can separate the " risky " operation from the rest of the process , and thereby insulate the rest of the process from the risk that the operation will fail or take a long time 通过使用消息队列来存储暂挂的确认电子邮件、库存检查或者信用检查，您可以将“有风险的”操作同过程的其余部分分离，因此也使过程的其余部分避免了操作失败或花费很长时间的风险。
