Question

Can you create an alias on field at time of creation? Example

 CREATE TABLE MYTABLE (                                           
    VERY_LONG_NAME       AS VLN  INT     NOT NULL )

Answer 1

No.

Why create a table with a VERY_LONG_NAME and then alias it? Simply choose A_BETTER_NAME to begin with.

In addition, it would be quite confusing to have a DB where columns are accessible by multiple names. How would you know which name was the actual name and which was the aliased name?

EDIT

As per @DavidFabers suggestion, if you must name your column VERY_LONG_NAME, you could create a view to allow you/users to access the column by a shorter name:

CREATE VIEW [vwMyTable] AS 
    SELECT  VERY_LONG_NAME AS A_BETTER_NAME
    FROM    MyTable
