In the Type drop-down list, choose String (this allows the column to contain alphanumeric values).ġ5. In the Display Name box, remove the spaces, so the name becomes Head of State.

Bad luck - it is not deterministic, which means that it doesn't return the same value each time you call it with the same parameters. Why? Because - in order to calculate someone's age - you have to refer to today's date. You were suggested to create a virtual column. So, what kind of information would be storing fixed age into that column? That person was 21 years old at the moment of insert, but they won't stay forever young. That was probably true at the moment of writing that text, but - is it still valid now? Two years later it should be "I've got 7 years of experience". It's the same as people - who fill their profile - say "I've got 5 years of experience with Oracle". No, you're planning to do it in a wrong way.
