Package.Execute Method

Returns a DTSExecResult enumeration that contains information about the success or failure of the package execution.

Namespace:  Microsoft.SqlServer.Dts.Runtime
Assembly:  Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)

Syntax

'Declaration
Public Function Execute As DTSExecResult
'Usage
Dim instance As Package
Dim returnValue As DTSExecResult

returnValue = instance.Execute()

public DTSExecResult Execute()

public:
DTSExecResult Execute()

member Execute : unit -> DTSExecResult 

public function Execute() : DTSExecResult

Remarks

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 runtime 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 Coding a Custom Task.

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 nulla null reference (Nothing in Visual Basic) 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 supports transactions but does not participate.

Examples

The following code example creates a package, sets the OfflineMode and InteractiveMode properties before adding a script task. It then runs the package using the Execute method.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.ScriptTask;

namespace Package_API
{
    class Program
    {
        static void Main(string[] args)
        {
            Package p = new Package();
            p.InteractiveMode = true;
            p.OfflineMode = true;

            // Add a Script Task to the package.
            TaskHost taskH = (TaskHost)p.Executables.Add(typeof(Microsoft.SqlServer.Dts.Tasks.ScriptTask.ScriptTask).AssemblyQualifiedName);
            // Run the package.
            p.Execute();
            // Review the results of the run.
            if (taskH.ExecutionResult == DTSExecResult.Failure || taskH.ExecutionStatus == DTSExecStatus.Abend)
                Console.WriteLine("Task failed or abended");
            else
                Console.WriteLine("Task ran successfully");
        }
    }
}
