The keyword NAMED is required in Teradata syntax. The keyword AS is optional.

The NAMED clause is enclosed in parentheses immediately following the renamed column.

AS is the ANSI SQL:2011 syntax. Teradata syntax using the NAMED clause is supported for backward compatibility. Use AS in place of NAMED for ANSI compliance. See AS.
