MySQL Error 1748: Row Partition Mismatch
Description
MySQL Error 1748, 'Found a row not matching the given partition set', occurs when a data row being inserted, updated, or moved does not fit into any of the predefined partitions for the table. This typically happens when the value of the partition key for the row falls outside the ranges or list values specified in the table's partition definition.

Known Causes
3 known causesPartition Key Value Out of Range
The value of the partitioning column for the row being processed does not fall within any of the defined partition ranges or match any list values.

Mismatched Partitioning Logic
The expression or function used for partitioning (e.g., `YEAR()`, `TO_DAYS()`) does not correctly align with the actual data being inserted or the partition definitions.
