MySQL Error 1654: Incorrect Partition Column Type
Description
This error indicates that the values being provided for a partition column do not conform to the column's defined data type. It typically occurs during data manipulation language (DML) operations like INSERT or UPDATE, or schema modification operations (DDL) such as ALTER TABLE, when MySQL attempts to evaluate partition expressions with incompatible data types.

Invalid Partition Expression
The partition expression or function used to define the table's partitions evaluates to a data type different from the partition column's expected type.
Schema Alteration Conflict
Modifying a partitioned table's schema (e.g., changing a partition column's data type) results in existing or incoming partition values becoming incompatible.
