Although there may be a simpler method, the following comes to mind right away:
Declare @SumVal int;
Select @SumVal=Sum(Amount) From Expense;
Print @SumVal;
Of course, you may use this method to print any number of table fields. Of course, you would just direct your output appropriately if you wanted to publish every result from a query that returns several rows (e.g. to Text).
I hope this helps you.
