Executable.Execute Method


Executes the executable.

 abstract Microsoft::SqlServer::Dts::Runtime::DTSExecResult Execute(Microsoft::SqlServer::Dts::Runtime::Connections ^ connections, Microsoft::SqlServer::Dts::Runtime::Variables ^ variables, Microsoft::SqlServer::Dts::Runtime::IDTSEvents ^ events, Microsoft::SqlServer::Dts::Runtime::IDTSLogging ^ log, System::Object ^ transaction);
public abstract Microsoft.SqlServer.Dts.Runtime.DTSExecResult Execute (Microsoft.SqlServer.Dts.Runtime.Connections connections, Microsoft.SqlServer.Dts.Runtime.Variables variables, Microsoft.SqlServer.Dts.Runtime.IDTSEvents events, Microsoft.SqlServer.Dts.Runtime.IDTSLogging log, object transaction);
abstract member Execute : Microsoft.SqlServer.Dts.Runtime.Connections * Microsoft.SqlServer.Dts.Runtime.Variables * Microsoft.SqlServer.Dts.Runtime.IDTSEvents * Microsoft.SqlServer.Dts.Runtime.IDTSLogging * obj -> Microsoft.SqlServer.Dts.Runtime.DTSExecResult
Public MustOverride Function Execute (connections As Connections, variables As Variables, events As IDTSEvents, log As IDTSLogging, transaction As Object) As DTSExecResult



A Connections collection.


A Variables collection.


An IDTSEvents interface to raise events.


An IDTSLogging interface.


The handle to a transaction type if participating in a transaction. This value can be null.


Returns a value from the DTSExecResult enumeration that indicates success, failure, or other status from running the executable.


The following code example shows how to run a package which inherits from the Executable class through the DtsContainer class. The package contains a BulkInsertTask. The Bulk Insert task is an example for this code sample; any task can be created in its place.

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

namespace Microsoft.SqlServer.SSIS.Samples  
    class Program  
        static void Main(string[] args)  
            Package p = new Package();  
            p.InteractiveMode = true;  
            p.OfflineMode = true;  
            Executable exec1 = pkg.Executables.Add("STOCK:BulkInsertTask");  
            TaskHost th = exec1 as TaskHost;  

            // Set the CheckConstraints and DataFileType properties.             
            th.Properties["CheckConstraints"].SetValue(th, true);  
            th.Properties["DataFileType"].SetValue(th, DTSBulkInsert_DataFileType.DTSBulkInsert_DataFileType_Native);  

            // Run the package that contains the task.  

            // Review the results of the run.  
            if (taskH.ExecutionResult == DTSExecResult.Failure || taskH.ExecutionStatus == DTSExecStatus.Abend)  
                Console.WriteLine("Task failed or abended");  
                Console.WriteLine("Task ran successfully");

                Console.WriteLine("Task failed or abended")  
                Console.WriteLine("Task ran successfully")

The Execute method is inherited by task hosts and other objects from this 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 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 supports transactions but does not participate.
