Github user cloud-fan commented on the pull request: https://github.com/apache/spark/pull/2543#issuecomment-60737418 Hi @marmbrus @liancheng, I think it's better to calculate the `ordinal` of `GetField` in analyze phase, and I have updated the code to introduce the `UnresolvedGetField`, and fix the case-sensitivity-check bug. Please let me know if you have any problems. Thanks!
