Get DDL of a table in BigQuery
How could I conveniently get the creating-SQL of a table in BigQuery? We could use INFORMATION_SCHEMA:
SELECT table_name, ddl FROM `data-to-insights.taxi.INFORMATION_SCHEMA.TABLES` WHERE table_name="tlc_yellow_trips_2018_sample"
Python
xxxxxxxxxx
SELECT
table_name,
ddl
FROM
`data-to-insights.taxi.INFORMATION_SCHEMA.TABLES`
WHERE
table_name="tlc_yellow_trips_2018_sample"
The result of ddl is:
CREATE TABLE `data-to-insights.taxi.tlc_yellow_trips_2018_sample` ( vendor_id STRING, pickup_datetime DATETIME, dropoff_datetime DATETIME, passenger_count INT64, trip_distance NUMERIC, rate_code STRING, store_and_fwd_flag STRING, payment_type STRING, fare_amount NUMERIC, extra NUMERIC, mta_tax NUMERIC, tip_amount NUMERIC, tolls_amount NUMERIC, imp_surcharge NUMERIC, total_amount NUMERIC, pickup_location_id STRING, dropoff_location_id STRING );
Python
xxxxxxxxxx
CREATE TABLE `data-to-insights.taxi.tlc_yellow_trips_2018_sample`
(
vendor_id STRING,
pickup_datetime DATETIME,
dropoff_datetime DATETIME,
passenger_count INT64,
trip_distance NUMERIC,
rate_code STRING,
store_and_fwd_flag STRING,
payment_type STRING,
fare_amount NUMERIC,
extra NUMERIC,
mta_tax NUMERIC,
tip_amount NUMERIC,
tolls_amount NUMERIC,
imp_surcharge NUMERIC,
total_amount NUMERIC,
pickup_location_id STRING,
dropoff_location_id STRING
);
