17.8. CREATE TABLE AS
Synopsis
CREATE TABLE [ IF NOT EXISTS ] table_name
[ WITH ( property_name = expression [, ...] ) ]
AS query
[ WITH [ NO ] DATA ]
Description
Create a new table containing the result of a SELECT query. Use CREATE TABLE to create an empty table.
The optional IF NOT EXISTS
clause causes the error to be
suppressed if the table already exists.
The optional WITH
clause can be used to set properties
on the newly created table. To list all available table
properties, run the following query:
SELECT * FROM system.metadata.table_properties
Examples
Create a new table orders_by_date
that summarizes orders
:
CREATE TABLE orders_by_date
WITH (format = 'ORC')
AS
SELECT orderdate, sum(totalprice) AS price
FROM orders
GROUP BY orderdate
Create the table orders_by_date
if it does not already exist:
CREATE TABLE IF NOT EXISTS orders_by_date AS
SELECT orderdate, sum(totalprice) AS price
FROM orders
GROUP BY orderdate
Create a new empty_nation
table with the same schema as nation
and no data:
CREATE TABLE empty_nation AS
SELECT *
FROM nation
WITH NO DATA
