Review Comment:
@Au-Miner Could you double check all changes made in
https://github.com/apache/flink/commit/ae4eb7dc3ae399659e52da39f7ac74242aaca3b5#diff-b2e1701d6c7cae434d495536a397325850d12a59023d320cbad9389aa7d17b2d
Don't we also need to restore the other lines SqlLikeUtils. If a character
(doesn't need to be the escape charater) is a special regex character, we need
to escape it.
