当使用SSIS中的Script. Task组件对SQL语句赋值时遇到如下报错:

The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.

 

完整报错:

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.
 ---> System.Runtime.InteropServices.COMException (0xC0010009): The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.

解决办法:

此问题由于Script. Task组件中编辑Script的时候引用到的变量未传入所致,因此在编辑脚本以前把要使用到的变量全部传入即可.如下图:
