morningman commented on issue #5657:
URL: https://github.com/apache/incubator-doris/issues/5657#issuecomment-822183509
when writing column mapping like:
(k1, k1=funcA(k1), k2=funcB(k1))
The expected rewriting is:
(k1, k1=funcA(k1), k2=funcB(funcA(k1)))
But when doing the substitution, it may encounter self referencing problem.
When replacing `k1` in `k2=funcB(k1)` with `funcA(k1)`, the `k1` in `funcA(k1)` is also referencing to `funcA(k1)`.
