Teradata Vantage™

A mandatory unique alias for a SUM, COUNT, MIN, MAX, or extracted year or month expression.

The keyword AS preceding expression_alias is optional.

All expressions specified in the select list must be aliased. Otherwise, Vantage returns an error to the requestor.

This name permits further use of the result as the grouping key for a GROUP BY clause or the ordering key for an ORDER BY clause.
