SSIS Script Task

The SSIS Script Task gives an option to implement functions that are not available or possible in the SSIS toolbox (both in built-in Tasks and transformations). The SSIS script task utilizes the Microsoft VSTA (Visual Studio Tools for Applications) as the code environment in which you can write the C# or VB Script.

TIP: SSIS Script Task VSTA provides all the standard futures available in general Visual Studio Environment.

SSIS Script Task Send Email

Drag and drop the Script Task from SSIS toolbox into the Control Flow region

Before we start configuring the SSIS Script task, let us create four variables. To create a variable, right-click on the control flow region, and it will open the context menu to select the variable option. Once you choose the variable option, it will open the new window called Variables to create the new variable.

Here you can create n variables

• EmailFrom: Please specify the Email ID from where you want to send the Email.
• EmailTo: Please specify the Email ID to whom you want to send the Email.
• EmailSubject: Please specify the Subject you want to include
• EmailBody: Please specify the Message. It can be Plain Text or HTML Message

Double click on the Script task will open the following editor to configure the SSIS Script task components

• EntryPoint: Please specify the Method name that the SSIS run-time calls as the entry point. The method name you specify here must be in ScriptMain class. Remember, you can change the name as per your requirement, and when you change it you have to change it in ScriptMain class

SSIS Script Task General tab

Please click on the General tab to change the default Name and Description.

• Name: Please provide the Unique Name
• Description: Briefly describe the SSIS Script Task Functionality. It is always a good practice to provide a valid description.

ScriptLanguage: Microsoft provides two of its popular languages: Visual Basic (VB) and C# to use as a scripting language. I am very much familiar with C# so, I am selecting C# as my script language.

• ReadOnlyVariables: Please select the variables that you want to use in the SSIS Script Task, and they may be user-defined variables or System default variables. Remember, variables selected as ReadOnlyVariables used for the Read-only purpose (we can’t alter them)
• ReadWriteVariables: Please select the variables that you want to use in the Script Task, and they may be user-defined variables or System default variables. Remember, variables selected as ReadWriteVariables can alter according to our requirement

To select the variables, please click on the Eclipse (…) button ReadOnlyVariables option

Once you click on the Eclipse (…) button, Select the Variables window will open. Please select the previously created variables

Add C# code in SSIS Script Task

Once you selected the required variable, please click on the Edit Script.. button to write the actual C# Script

Once you click on the Edit Script, it will open the ScriptMain.cs class file to write the C# code.

To send an email from C# we need to add two references or import references called: using System.Net; and using System.Net.Mail;

TIP: If you are VB developer then it should be something like ScriptMain.vb

Next, within the Main() function add your Code. Remember, if your code is long or robust, try to divide the code by creating methods

C# code we used for this SSIS Script Task in the above screenshot is:

// C# Script for Script Task in SSIS
String SendMailFrom = Dts.Variables["EmailFrom"].Value.ToString();
String SendMailTo = Dts.Variables["EmailTo"].Value.ToString();
String SendMailSubject = Dts.Variables["EmailSubject"].Value.ToString();
String SendMailBody = Dts.Variables["EmailBody"].Value.ToString();

try
  {
     MailMessage email = new MailMessage();
     SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
     // START
     email.From = new MailAddress(SendMailFrom);
     email.To.Add(SendMailTo);
     email.Subject = SendMailSubject;
     email.Body = SendMailBody;
     //END

     SmtpServer.Port = 587;
     SmtpServer.Credentials = new System.Net.NetworkCredential(SendMailFrom, "your password");
     SmtpServer.EnableSsl = true;

     SmtpServer.Send(email);
     MessageBox.Show("Email was Successfully Sent ");
  }
catch (Exception ex)
  {
      MessageBox.Show(ex.ToString());
  }
Dts.TaskResult = (int)ScriptResults.Success;

If you forgot to create Variables (or if you find it difficult to create variables) then, you can remove the first four lines of code and replace the code between //Start… END with the below-shown code

// SSIS Script Task Example
email.From = new MailAddress("[email protected]");
email.To.Add("[email protected]");
email.Subject = "Test Mail";
email.Body = "This Email is coming from SSIS Script Task";

Once you finished editing the Script, Please close the ScriptMain.cs file and Script Task Editor. Let us run the SSIS Script Task package

From the above screenshot, you can observe that SSIS Script Task is successful, and we got the message box saying that Email was Successfully sent. Let me open my Gmail

From the above screenshot, you can see that we got the Email with the message we specified.

Points to Remember for this Script Task :

• If you want to send an email to your Manager (or to yourself) after every Data Load then, you can use this SSIS Script task along with the Data Flow Task.
• Always use the Variables for storing Emails, Passwords, Subject, or SMTP credentials.
• If there is an Error stating Secure Connection then, Go To Less Secure Apps in your Gmail account settings and Turn on the Access for Less Secure Apps option.
