In a Select Statement, how do you create a temporary column to display calc results?

I know there is a way to create a temporary column as part of a basic Select Statement search that shows the result of mathematical calculations done in that search, but I can't remember the syntax and googling it has been a wash out.

I have a list of classes in a database. I need to list all classes with less than 12 students in them, that's fine. But I also need add a column that shows the number of students necessary to bring the class total up to 12.

There's not really a syntax, you just put in the expression. If you want to give it a column name, you use the AS predicate, but that's optional.

  1. SELECT col1, 
  2.    col2, 
  3.    col1 + col2 AS sumCol
  4. FROM table1
