sql server - T-SQL - Aliasing using "=" versus "as" -

-

is there particular reason (performance or otherwise) use ahead of = when aliasing column?

my personal preference (for readability) use this:

select alias1     = somecolumn alias2     = anothercolumn tables etc...

instead of this:

select somecolumn alias1 anothercolumn alias2 tables etc...

am missing out on reason why shouldn't doing this? other people's preferences when comes formatting columns?

‘=’ isn't valid ansi sql, you'll have difficulty should wish run application on different dbms.

(it's when ansi form used optional ‘as’ omitted find results difficult read, personally.)
