Removed this since it fails on mysql. a is not the same as a collate utf8_general_ci, so if full_group_by is enabled, this query would fail

[systay]

this query fails on both mysql and vitess. name is not accessible on the having clause

[harshit-gangal]

This query does not fail anymore, we should bring the test back.

does this mean we will start failing queries for group by/ having if the schema tracking is not enabled?

your comment was not connected to anything I could see, so I'm not sure what the question is about. Generally - if you are grouping by an alias introduced in the SELECT expression, and we have to do some or most of the aggregating on the vtgate, queries might start having issues if you are running without schema tracking
