BigQuery - 列出日期分區表的分區？

Question

查詢 - 從Mydataset.Table$__PARTITIONS_SUMMARY__選擇partition_id; 給error--表 「PARTITIONS_SUMMARY Mydataset.Table $ 」 下面不能包含decorator`

Answer 1

下面嘗試在傳統的SQL

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

及以下標準的SQL

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

這也適用於Legacy SQL

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