BigQuery - 列出日期分区表的分区？

Question

Answer 1

在传统SQL中尝试以下

SELECT project_id,
    dataset_id,
    table_id,
    partition_id,
    TIMESTAMP(creation_time/1000) AS creation_time
FROM [Mydataset.Table$__PARTITIONS_SUMMARY__]

标准SQL的

及以下

SELECT _PARTITIONTIME as pt
FROM `Mydataset.Table`
GROUP BY 1

也适用于旧版SQL

SELECT _PARTITIONTIME as pt
FROM [Mydataset.Table]
GROUP BY 1
