Description
Error 1634, 'Subpartition', indicates a problem with the definition or naming of a subpartition within a partitioned table in MySQL. This usually arises during `CREATE TABLE` or `ALTER TABLE` statements when the subpartition specification is invalid, conflicts with existing definitions, or violates MySQL's partitioning rules.

Known Causes

Subpartition Definition Mismatch ⚙
This can occur if the number of subpartitions defined does not match the expected number based on the `SUBPARTITIONS` clause, or if subpartitioning rules (e.g., for `LIST` or `RANGE` partitioning) are violated.
