ODPS表t1、t2都是分区表,分区键是pt,对于sql语句select t1.id from t1 left&nb
但以下官方文件, 答案好像是Dhttps://www.alibabacloud.com/help/doc-detail/89993.html
If Left join In the third case, the where condition filter after JOIN
SELECT A.*, B.*
FROM A JOIN B
ON a.key = b.key
WHERE A.ds='20180101' and B.ds='20180101';
For example, there are nine results of Descartes that meet the ON a.key = b.key there are 3 results for key, respectively:
a.key a.ds b.key b.ds
1 20180101 1 20180101
2 20180101 2 20180102
2 20180102 2 20180102
沒有進行分區裁剪.....
