danny0405 opened a new pull request #2101: URL: https://github.com/apache/calcite/pull/2101
The root cause is that the operands type was wrongly replaced by SqlToRelConverter#adjustInputRef, actually, for a agg as root, there is no need to do any adjust. because the nullability does not change and the agg type is not same with the bb's scope. To fix, tweak the #adjustInputRef to only fix type nullability, if there are cases that the type name also changes, just return the original node and let the subsequent conversion work flow throws. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
