To demonstrate this feature, I’ll use an Athena table querying an S3 bucket with ~666MBs of raw CSV files (see Using Parquet on Athena to Save Money on AWS on how to create the table (and learn the benefit of using Parquet)). For information, see WITH (format = 'PARQUET'). You can also use the SQL CREATE TABLE AS statement to create a table from an existing table by copying the existing table's columns. to create your table in the following location: The data format for the CTAS query results, such as If WITH NO DATA is used, a new empty table with the same Currently, multicharacter field delimiters are not supported for Javascript is disabled or is unavailable in your Athena stores data files created by the CTAS statement in a specified location in Amazon S3. The data files are stored in Amazon S3 at the designated location. CTAS is the simplest and fastest way to create and insert data into a table with a single command. You can learn something new everyday, and today I learned that AWS Athena supports INSERT INTO queries. the documentation better.

See: SQL Reference for CREATE EXTERNAL TABLE. athena-express makes it easier to execute SQL queries on Amazon Athena by chaining together a bunch of methods in the AWS SDK. An array list of buckets to bucket data. Here if you do not want all the columns, you can specify the name of the column as well, instead of SELECT *. The condition WHERE 1 = 2 will return no rows and the new table will be created with no rows.
