Examples of CREATE TABLE AS
This section shows the column attribute rules used to generate and specify the column names
and data types of the table being created.

If column-attributes are not specified, the select list items of the select-query are used
to generate the column names and data attributes of the created table. If the select list item
is a column, then it is used as the name of the created column. For example:
create table t no partition as select a,b from t1
