> Computing a schema for a wildcard differs from expanding the actual expressions that match the wildcard I think their logic is basically the same, otherwise there would be issues similar to #14102. Another potential issue is that in [exprlist_to_fields](https://github.com/apache/datafusion/blob/f9cc3325cdb5891b7566a6f3503c1f7ac6ad51e0/datafusion/expr/src/utils.rs#L696), we don't handle replace items, but ExpandWildcardRule does. `select * replace ('foo' as a) from t` will give the wrong datatype in schema before executing analyzer. -- This is an automated message from the Apache Git Service.
