BigQuery - 列出日期分区表的分区？

Question

查询 - 从Mydataset.Table$__PARTITIONS_SUMMARY__选择partition_id; 给error--表 “PARTITIONS_SUMMARY Mydataset.Table $ ” 下面不能包含decorator`

Answer 1

下面尝试在传统的SQL

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

及以下标准的SQL

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

这也适用于Legacy SQL

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