MySQL Error 1731: Partition-Table Attribute Mismatch
Description
Error 1731 indicates a structural inconsistency when attempting to exchange a partition with a table using the `ALTER TABLE ... EXCHANGE PARTITION` statement. This error occurs because MySQL requires the table being exchanged with a partition to have an identical definition, including its storage engine, column definitions, indexes, and other table options, to ensure data integrity and operational compatibility.
Error Message
Non matching attribute '%s' between partition and table
Known Causes
4 known causesDifferent Storage Engines
The table intended for exchange has a different storage engine (e.g., MyISAM vs. InnoDB) than the partition it's replacing.
Mismatched Column Definitions
Columns in the table and partition have differing data types, lengths, nullability, or default values.
Discrepant Table Options
Other table options such as `ROW_FORMAT`, `CHARACTER SET`, `COLLATE`, or `KEY_BLOCK_SIZE` do not match between the table and the partition.
Missing or Extra Indexes
The table and partition have different primary keys or secondary indexes defined, leading to structural non-conformity.
