2.11.1.As

Defining a new structural element (table or column) by aliasing an existing value.

A common use for this is to create a shorthand reference to elements with long names to make the SQL statements shorter.

SELECT <columns>

FROM <existing_table_name>

AS <new_table_name>

is simply a reference that exists for the duration of the SQL statement.

SELECT t1.first_name

FROM employee

AS t1;
