Examples

Create an external table from S3 parquet file:

CREATE EXTERNAL TABLE test STORED AS PARQUET
LOCATION 's3://path-to-your.parquet';

Create an external table from HTTP parquet file:

CREATE EXTERNAL TABLE lineitem
STORED AS PARQUET
LOCATION 'https://shell.duckdb.org/data/tpch/0_01/parquet/lineitem.parquet';

EXPLAIN SELECT MIN(airport_fee), MAX(airport_fee) FROM test;
