Wondering if the new table doesn't have the same column name of source table pk. How do we deal with such case.
This isn’t about the current PR. Just want to know if this is a reasonable constrait.

If the source table can not find the same column as the PK. When doing the join action in Data Fusion, it would throw an exception.
