@yjshen After trying the following 2 cases in Hive 2.3.7, I got the outputs below: ``` hive> set hive.cli.print.header=true; hive> select 1,2; OK _c0 _c1 1 2 Time taken: 0.272 seconds, Fetched: 1 row(s) hive> SELECT coalesce(NULL, 1, NULL); OK _c0 1 Time taken: 0.228 seconds, Fetched: 1 row(s) ``` In my opinion, Hive auto alias convention `_c0` seems more reasonable since that indicates column index. I prefer doing this in Datafusion. What do you think? @xudong963 @yjshen -- This is an automated message from the Apache Git Service.
