Sql server union but keep order

Question

Is there a way to union two tables, but keep the rows from the first table appearing first in the result set?

For example:

Table1

name                


        

Answer 1

;WITH cte as (
    SELECT name, surname, 1 as n FROM table1
    UNION ALL
    SELECT name, surname, 2 as n FROM table2
    UNION ALL
    SELECT name, surname, 3 as n FROM table3
)
SELECT name, surname
FROM cte
ORDER BY n;
