MySQL Error 1656: Invalid MAXVALUE in VALUES IN
Description
This error occurs when the special keyword `MAXVALUE` is used incorrectly within a `VALUES IN` clause. `MAXVALUE` is intended for defining an upper boundary in range-based operations (like `RANGE` partitioning), not as a literal value to be included in a list of discrete values. It signals a fundamental misunderstanding of its syntactic and semantic role in MySQL.
Error Message
Cannot use MAXVALUE as value in VALUES IN
