Lets say I have a table called Players and another table called Coaches.

Each table has columns FirstName, LastName, UserID, Address.

There is currently a view called PeopleView which is a simple select statement.

    select FirstName, LastName, UserID from Players;

I now want PeopleView to also return the same data from the Coaches table.

    select FirstName, LastName, UserID from Coaches;

So now when this view is executed it will show all players and coaches in the database even though you will not know which record is a coach or player.

Thanks and I am hoping this is easy for sql experts.

But, you can know who is who by adding yet another column:

select 'Player' what, FirstName, LastName, UserID from Players
union all
select 'Coach'  what, FirstName, LastName, UserID from Coaches
