Issue Number: close #20669 RewriteInPredicateRule may cast InPredicate expr's two child to the same type, for example: where cast(age as char) in ('11'), the type of age is int, RewriteInPredicateRule will cast expr's two child type to int. As in the example above, child 0 will be such struct: ``` child 0: type: int |--- child: type : char |-- child: type : int ``` Due to the RewriteInPredicateRule cast the type of the expr to int, it will reanalyze stmt, but it will reset stmt first before reanalyze the stmt, and reset opt will change child 0 to such struct: ``` child: type : char |-- child: type : int ``` It cause two child's type will be cast to varchar in func castAllToCompatibleType, the logic of RewriteInPredicateRule will be useless. In 1.1-lts and 1.2-lts, such case " where cast(age as char) in ('11')" can't work well, because func castAllToCompatibleType will cast int to char but int can't cast to char(master can work well because func castAllToCompatibleType will cast int to varchar in such case). ``` MySQL [test]> select user_id from test_cast where cast(age as char) in ('45'); ERROR 1105 (HY000): errCode = 2, detailMessage = type not match, originType=INT, targeType=CHAR(*) ```
