A valid SQL expression.

You can specify both aggregate and arithmetic operators in a view definition expression.

You cannot specify a SAMPLE clause if the view definition also includes a TOP n or TOP m PERCENT specification.

The presence of aggregates in a view definition renders that view non-updatable.

AS
An optional introduction to expression_alias.
expression_alias
A temporary name for the expression.
Alias names are used to name expressions and must be always be specified for a self-join operation on the table.
