[GitHub] [doris] BiteTheDDDDt commented on pull request #11212: [fix] the nullable info is lost in ifnull expr
BiteTheDDDDt commented on PR #11212:
URL: https://github.com/apache/doris/pull/11212#issuecomment-1195392540
Do you have any case to repeat the error?
```java
if (children.get(0).isNullable()) {
return children.get(1).isNullable();
}
```
The nullable here needs to be consistent with `FE`, I think we should do more change at `ifnull`.
This is the modification of get_return_type_impl, we also need to implement similar logic in execute_impl
