返回值

备注

The Execute method is inherited by task hosts and other objects from the Executable abstract class, through the DtsContainer class, and allows the inheriting objects to be run by the run-time engine. The Execute method inherited by the individual objects is not commonly used in code, and it is recommended that you call the Execute method if you need to run any of the tasks or containers in the package. However, the Execute method is available on individual objects should you find a unique circumstance where it is needed.

The main use of the Execute method is for it to be inherited and overridden when you create a custom task. For more information about how to override the Execute method, see Implementing the Execute Method in Custom Integration Services Tasks.

The Execute method calls the Validate method implicitly before the package runs. All tasks in the package are reviewed for appropriate settings during validation, and all objects in the package are reviewed, including the package, containers, and other components in the package.

If there are no problems encountered in the validation phase that would cause the package to fail, the package object proceeds to call the Execute method for each task and object in the package.

Pass null for the transaction parameter when the TransactionOption property is false. If the TransactionOption property is true, you can pass null in the transaction parameter to indicate that the container support transactions but is not going to participate.
