是否可以在SSIS包中的两个现有任务之间插入数据流任务?
我有一个非常好的数据流。在测试数据流逻辑的过程中,我发现在现有的数据流逻辑之间需要一个额外的数据流任务。
是否可以在现有任务之间插入新任务?

您需要删除连接两个控制流任务的优先级约束,然后在两个现有任务之间拖放新任务。将第一个任务的优先级约束连接到新任务,将新任务的优先级限制连接到现有的第二个任务。
优先级约束
是两个控制流任务之间的箭头,表示流的方向。箭头可能以green
、red或blue
//em>的颜色出现,具体取决于用于引导流的条件。
如果优先级约束
上有一个表达式,则在删除优先级约束之前,必须记下该表达式是什么。在引入新任务后,您可能需要再次使用该表达式。
假设您有一个名为SO_6115881.dtsx
的SSIS包。在该包中,“控制流”选项卡上有两个数据流任务。下面显示的屏幕截图表明优先级约束上没有表达式或约束(绿色箭头)。
如果在优先级约束上定义了表达式,则字母fx将出现在优先级约束上。
您可以双击优先级约束来查看优先级约束编辑器
以记录所使用的表达式。这里,优先级约束使用表达式@[User::IsValid]==True
来验证包变量@[User::IsValid]
的计算结果是否为True。
让我们假设在两个现有的控制流任务之间没有表达式。要删除优先约束,请单击它并按删除,或右键单击优先约束并单击删除
。
删除优先级约束后,在两个现有任务之间拖放下一个控制流任务。从任务数据流任务1
拖动优先级约束,并将其连接到新任务new Data Flow task
。
从新任务新数据流任务
拖动优先级约束,并将其连接到任务Data Flow task 2
。现在,您应该已经在两个现有任务之间成功添加了新的控制流任务。如果有表达式,请双击相应的优先级约束以添加该表达式。
