**Describe the bug** When invoke nullable(), if plan is semi/anti join, all_schema() only just contain one side child output. If we want to compute expr, it will fail. like: ```sql t1 semi join t2 on t1.id = t2.id ``` due to schema just is `[t1.id] (join), [t1.id](left) , [t2.id] (right)`. so `t1.id = t2.id` can't invoke `nullable()` **To Reproduce** Steps to reproduce the behavior: **Expected behavior** A clear and concise description of what you expected to happen. **Additional context** Add any other context about the problem here. -- This is an automated message from the Apache Git Service.
