Its a very general and regular ways to use
Order by clause with Column Name to Specifies the sort order used on columns returned in a SELECT statement.
Syntax :-
order by columnname asc/desc
I am also using the same method but do you know we can use Column Index (Integer representing the position of column name) instead of specifying the name or column alias in a SQL Server Order By expression.
As:-
order by Column_Index_Number asc/desc
we can use both queries because both of these queries having the same results.
let check both syntax and result too
here I am going to query based on AdventureWork database
Example :- Getting top 10 value from Employee table based on EmployeeID in asc order
select top 10 * from HumanResources.Employee order by EmployeeID asc
output will be as given below :-
when Using Column Index instead of Column Name for same query
Note :- Column Index can be changed as 1,2,3,etc based on column name condition
select top 10 * from HumanResources.Employee order by 1 asc
then output will be same as given below :-

Note :- ORDER BY clause is only Clause where we can you use the ordinal position[Column Numbers], because it's based on the column(s) specified in the SELECT clause.
its generally
recommended that to use Column Name instead of Column Number. but in some cases using Column Number can be useful like it can be
used it in a dynamic sql where column names are unknown.
