alamb opened a new issue, #14855: URL: https://github.com/apache/datafusion/issues/14855
### Describe the bug @jonahgao noticed this in https://github.com/apache/datafusion/pull/14824 This query works in DataFusion 44 and 45: ```sql select count(), count(*); ``` However, it does not work on main (what would become DataFusion 46) ``` DataFusion CLI v45.0.0 > select count(), count(*); Error during planning: Projections require unique expression names but the expression "count(*)" at position 0 and "count(*)" at position 1 have the same name. Consider aliasing ("AS") one of them. > ``` ### To Reproduce _No response_ ### Expected behavior The query should produce the same results as in datafusion 44 and 45 ```shell andrewlamb@Andrews-MacBook-Pro-2:~/Software/datafusion$ ~/Downloads/datafusion-cli-44 DataFusion CLI v44.0.0 > select count(), count(*); +---------+----------+ | count() | count(*) | +---------+----------+ | 1 | 1 | +---------+----------+ 1 row(s) fetched. Elapsed 0.013 seconds. > \q andrewlamb@Andrews-MacBook-Pro-2:~/Software/datafusion$ ~/Downloads/datafusion-cli-45 DataFusion CLI v45.0.0 > select count(), count(*); +---------+----------+ | count() | count(*) | +---------+----------+ | 1 | 1 | +---------+----------+ 1 row(s) fetched.
