SELECT statement - add another derived field
===

I have a table which has 3 columns. `Name`,`DateOfBirth`, `DateDeceded`. The fields `DateOfBirth` and `DateDeceded` have the data type `DATE`.

Now when i do a `Select * from TableName`. I want to display the Name, date of birth, date deceded and the number of years the person lived (`DateDeceded` - `DateOfBirth`).

How do i write the SQL Select statement to include the `NumberOfYearsLived` field ?
