If specified, the table is created only for this session, and is

|
automatically dropped on session exit.
|
|
Existing permanent tables with the same name are not visible
|
|
(in this session) while the temporary table exists.
|
|
Any indexes created on a temporary table are automatically
|
|
temporary as well.

|
|
<para>
|
|
<command>CREATE TABLE AS</command> enables a table to be created
|
|
from the contents of an existing table.
|
|
It is functionally equivalent to
|
|
<xref linkend="sql-selectinto" endterm="sql-selectinto-title">,
|
|
but with perhaps a more direct syntax.
