mpurins-coralogix opened a new issue, #5610:
URL: https://github.com/apache/arrow-datafusion/issues/5610
**Describe the bug**
I have found that under certain conditions casts are lost when there is a
sort on expression with cast, and that could result in incorrect query results
(for example if cast would be from string to integer).
**To Reproduce**
We hit this when building plan with `LogicalPlanBuilder` directly, but
following sql will trigger this as well.
Query `SELECT first_name AS first_name FROM (SELECT first_name AS first_name
FROM person) ORDER BY CAST(first_name as INT)` gives us
```
Sort: first_name AS first_name ASC NULLS LAST
Projection: first_name AS first_name
Projection: person.first_name AS first_name
TableScan: person
```
**Expected behavior**
Query above should give us something like
```
Sort: CAST(first_name AS Int32) ASC NULLS LAST
Projection: first_name AS first_name
Projection: person.first_name AS first_name
TableScan: person
```
