Expressions

If you are the least bit familiar with programming languages, you know that expressions are anything that, when calculated, result in a value. For instance, 1 + 1 = 2 is an example of an expression. Expressions in SQL work similarly. Consider the following data that could appear in the Employees table:

EmployeeIDFirstNameLastName
1AdaSpada
2AgnesSenga
