Using SSIS to send emails to a table of people

Another blog arising from a question from a recent course (it's how I learn): how do you send emails to people whose addresses are held in SQL Server?

Suppose that you have created a table or view to hold a number of email addresses, and you want to send the same email to each.

Step 1 - Creating the variables needed

The first thing to do is to create two variables:

The two variables we'll need.

Here's what these will be used for:

Step 2 - read the rows into the object variable

The next step is to read the rows into your ViewRows variable.  First add an Execute SQL task:

Add a task to read in the rows.

Now edit this task to store the results:

The task selects one column from our view, and puts the data returned into a results set.

Now use the Result Set tab to specify that you'll store the first (and only) results set in our object variable:

You'll need first to click on the Add button to add a results set into the grid.

Step 3 - looping over each row

You now need to add a FOREACH loop to loop over each row:

This task will run once for each row in the results set.

Edit this task to loop over the ADO rows stored in the ViewRows variable:

These settings are in the Collection tab for the FOREACH loop.

On the Variable Mappings tab, choose to store the first (and as it happens, only) bit of information for each row in the EmailAddress variable:

The SQL statement returned only one column - we capture the value of this in the string variable each time round the loop.

Step 4 - sending the email

Having done the hard part, we can now send each email.  First add a Send Mail task within the loop:

This task will send an email for each pass through the loop.

What we'd like to do now is put the variable name in as the To field for the email, but SSIS won't let us do this:

The To property can't take an expression.

What you can do though is to add an expression:

Use this tab to add an expression.

Choose to add an expression:

Click on this button to the right of the dialog box to create a new expression.

You can now assign the variable to the To field:

Success! We've assigned each email address to the To line of each email.
