You can find more information about adding columns to table in Athena documentation
Or you can use CTAS
For example, you have a table with
CREATE EXTERNAL TABLE sample_test(
id string)
LOCATION
's3://bucket/path'
and you can create another table from sample_test with the query
CREATE TABLE new_test
AS
SELECT *, 'new' AS new_col FROM sample_test
You can use any available query after AS
