Hi chenchen：

Thank you for your report.

I reproduced the problem you described and I think the parse of CASE WHEN in kylin have some bug.

We will fix these bugs in future version.

> in this version,
> In SQL statements with case-when, when the name of the field is the same as that of the case-when-as field, the result of the query is not converted to the corresponding string.
> But when I put the case when outside the braces, the query was correct again.
> I suspect that "group by" has changed the order in which SQL is executed.
> I wonder if there is a lack of configuration when I upgrade?
