<p>MySQL raises error 1567 (ER_WRONG_PARTITION_NAME) when a partition name in CREATE or ALTER TABLE violates naming rules such as length, character set, or duplication.</p>
<p>MySQL Error 1567: ER_WRONG_PARTITION_NAME appears when a partition name is invalid or already used. Rename the partition or recreate it with a legal, unique identifier to fix the problem.</p>
Incorrect partition name
MySQL throws Error 1567 with the message Incorrect partition name when a CREATE TABLE or ALTER TABLE ... PARTITION statement references a partition identifier that breaks naming conventions. The parser stops execution before any data change is committed, making this a compile-time error.
The error surfaces while creating a partitioned table, adding new partitions, renaming partitions, or restoring dumps that contain partition definitions. It immediately follows the first invalid identifier MySQL parses.
Failing DDL blocks schema migrations, automated deployment pipelines, and data loading tasks. Clearing the error ensures partitions are created correctly, keeps queries using partition pruning fast, and prevents downtime in production workflows.
Names must be ASCII, case-insensitive, 64 characters or fewer, start with a letter or underscore, avoid reserved keywords, be unique within the table, and match any explicit partition naming pattern you enforce through automation.
Spaces, hyphens, accented letters, or non-ASCII symbols break MySQL's identifier rules and trigger the error.
Reusing an existing partition name in the same table causes a collision detected by the parser.
Long auto-generated names from CI pipelines can silently breach the maximum length allowed by MySQL.
Using keywords like SELECT or a name made entirely of digits conflicts with MySQL grammar and fails validation.
Occurs when partition options conflict with storage engine capabilities.
Raised when a partition referenced in SQL does not exist in the table.
Appears when attempting to add a partition that already exists by name or boundary.
No. Hyphens are treated as minus operators in MySQL grammar and cause Error 1567.
Partition names are case-insensitive by default, but keeping a single casing style avoids confusion.
The identifier must not exceed 64 characters or MySQL will return ER_WRONG_PARTITION_NAME.
Renaming a partition is metadata-only and does not move rows, so data remains intact.
