我需要按大小列出数据集顺序中的所有BQ表,以找出占用更多空间的表。怎么做到这一点?
谢谢!

#standardSQL
SELECT table_id,
DATE(TIMESTAMP_MILLIS(creation_time)) AS creation_date,
DATE(TIMESTAMP_MILLIS(last_modified_time)) AS last_modified_date,
row_count,
size_bytes,
CASE
WHEN type = 1 THEN 'table'
WHEN type = 2 THEN 'view'
WHEN type = 3 THEN 'external'
ELSE '?'
END AS type,
TIMESTAMP_MILLIS(creation_time) AS creation_time,
TIMESTAMP_MILLIS(last_modified_time) AS last_modified_time,
dataset_id,
project_id
FROM `yourProject.yourDataset.__TABLES__`
ORDER BY size_bytes DESC
以上查询为您提供的不仅仅是尺寸 - 享受:o)
