[dba-SQLServer] interesting trick

The number to refer to column ordinal position is only in the order by
clause. 
In a column list, you can include any expression or literal, it doesn't have
to be a column from the table. 

The simplest select statement is SELECT 1
Everything else is optional

Using SELECT 1 instead of SELECT * -- I know you can use a number to refer 
to a column's position, but its uses are limited. I found this reason 
interesting and probably wouldn't have thought of it on my own.
