Описание#
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
