Using the INTO Clause
The INTO clause of the SELECT statement creates a new table based on the columns and rows of the query results.
The syntax for INTO is as follows:
SELECT select_list
[INTO new_table_name]
FROM table_list
The INTO clause is followed by the new table name which must not already exist.
This can be a permanent, temporary, or global temporary table.
