屬性值

A custom Variable that contains the execution value.

備註

The name of the custom variable that contains the execution value for the task. The default value of this property is none, which indicates that the result is not set to a variable in the package.

A task can use the ExecutionValue property to provide information about the results of the Execute method. This optional information supplements the Success or Failure status returned by the ExecutionResult property. For example, if a task deletes rows from a table, the task might return the number of rows deleted as the ExecutionValue.

However, to use the ExecutionValue later in the workflow of the package, for example, in a precedence constraint, you must save its value in an existing package variable. You use the ExecValueVariable property to specify the variable that will hold the ExecutionValue.
