SQL Age Difference Calculation

Hi,

I need your help with a requirement.
I need to calculate the current age of the employee from the hire_date and would need that Age in a new column - Current_Age. How will I do that ? Please support your answer with a screenshot of an executed query of the above.

P.S. - This question is not a part of the course but a general question I thought of.

Thanks,
Archie
