在Package的执行过程中,如果在Data Flow中出现Error,那么Data Flow component能够将错误行输出,只需要在组件的ErrorOutput中进行简单地配置,参考<Data Flow的Error Output>.相比Data Flow,Control Flow对OnError事件的处理更加复杂和精细,主要需要考虑到以下5个方面: 1,在Control Flow中,Package本身,Task 和 Container具有属性 MaximumErrorCount 2,O…

3.8. Control FlowJava, like any programming language, supports both conditional statements and loops to determine control flow. We will start with the conditional statements, then move on to loops, to end with the somewhat cumbersome switch statement…

介绍 在本文中,我们会实验 MaximumErrorCount和ForceExecutioResult 故障容差属性,并且还要学习Control Flow task errors, event handlers 和 containers 的联系 关于 SSIS Task Errors 打开 Precedence.dtsx 包. 你的Control Flow 显示如下: 图 1 再做测试前我们先调整两个优先约束.   Script Task 4 和 Script Task 3  调整如下: 图 2…

Exceptional Control Flow The program counter assumes a sequence of values                                  a0,a1,...,an−1 where each ak is the address of some corresponding instruction Ik. Each transition from ak to ak +1 is called a control transfer…

prcesssor在运行时,假设program counter的值为a0, a1, ... , an-1,每个ak表示相对应的instruction的地址.从ak到ak+1的变化被称为control transfer.一系列的control transfers被称为control flow. exceptions是指一些event,这些event表明当前的system.processor或executing program存在某些状况(详见1.2).exceptions会导致control fl…

Control Flow 和 Data Flow,是SSIS Design中主要用到的两个Tab,理解这两个Tab的作用,对设计更高效的package十分重要. 一,Control Flow 在Control Flow中,Task是最小的单元,Task通过Precedence Constraint来保持同步,在对后续Task进行处理之前,必须完成前面Task(成功,失败或者完成). 1,Control Flow 不能在组件之间传递数据,用于串行或并行执行任务,担当Task的调度者. 如果两个Ta…

1.一个package包含一个control flow并且一个或多个data flow. (这个项目叫做 Integration services project,提供了三种不同类型的control flow 元件) 1.1 containers(provide structures in packages) 1.2 tasks(provide functionality) 1.3 precedence constraints (connect the executables, containe…

In the Control Flow, the task is the smallest unit of work, and a task requires completion (success, failure, or just completion) before subsequent tasks are handled. Workflow orchestration Process-oriented Serial or parallel tasks execution Synchrono…
