来自多个表的Google BigQuery-Joined Resultset

Question

您好我每天都会将Google Analytics CostData导入Google BigQuery，每天都会创建类似Costdata_yyyymmdd的表格。我需要在所有日期表的Select查询中加入结果。

表名

Costdata_20180401

Costdata_20180402

Costdata_20180403

Costdata_20180404

Costdata_20180405 ..... Costdata_yyyymmdd

必填结果：

select * from Costdata_20180401
union all 
select * from Costdata_20180402 
union all Costdata_yyyymmdd

Google BigQuery实现此目标的最佳方法是什么？

您可以对此https://cloud.google.com/bigquery/docs/reference/standard-sql/wildcard-table-reference

使用表格通配符

SELECT * 
FROM  ´Costdata_*´ 
WHERE _table_suffix 
  BETWEEN '20180401' AND '20180413'
