Updating table from another table using memory tables

Hello Guys,

I'm trying to uptade a memory table from another memory tabble like the code bellow.
but I'm geting the error saying (Must declare the scalar variable "@source".)

Is there any way how to do this using memory table ?


 declare @source table (id int, name varchar(30), surname varchar(30))
 declare @copy table (id int, name varchar(30), surname varchar(30))
 insert into @source (id,name,surname) values(1,'michel','mortarello')
 insert into @source (id,name,surname) values(2,'michel','mortarello')

 insert into @copy (id,name) values(1,'michel')
 insert into @copy (id,name) values(2,'michel')

 update @copy
      set surname = @source.surname
      from @copy inner join @source on @source.id = @copy.id
 select * from @copy

Many thanks guys
