What is MySQL error 1522 (ER_PART_STATE_ERROR)?

<p>ER_PART_STATE_ERROR (MySQL 1522) occurs when a CREATE or ALTER TABLE includes unsupported partition state options. Remove those options or use proper ALTER PARTITION syntax to fix the problem.</p>

What is MySQL error 1522 (ER_PART_STATE_ERROR)?

Error 1522 happens when a statement tries to define partition-level state attributes that MySQL reserves for internal use. The server blocks the operation and returns: Partition state cannot be defined from CREATE/ALTER TABLE.

The condition indicates that the DDL touched keywords such as ENGINE, NODEGROUP, TABLESPACE, STORAGE, or COMMENT inside a PARTITION clause. MySQL allows those attributes only in specific ALTER PARTITION commands, not in a general CREATE or ALTER TABLE.

What Causes This Error?

The most frequent trigger is copying example code written for NDB Cluster into InnoDB or MyISAM tables. Those examples often include PARTITION ... ENGINE = ndbcluster which fails in other engines. Another common cause is using NODEGROUP or COMMENT inside a partition definition when the table engine does not support it.

Developers may also hit the error when trying to move a table from one engine to another and leaving obsolete partition options in the script. Automated schema-generation tools can inject unsupported options as well.

How to Fix MySQL Error 1522

First review the PARTITION clauses and remove any state attributes that MySQL flags. Keep only allowable items like VALUES LESS THAN or VALUES IN. If you must adjust engine or tablespace, use ALTER TABLE ... ENGINE or ALTER TABLE ... TABLESPACE at the table level instead of inside each PARTITION.

When you really need partition-level options, issue ALTER TABLE ... ALTER PARTITION commands in separate statements. That approach satisfies MySQL's rules and avoids error 1522.

Common Scenarios and Solutions

Copying NDB scripts into a standard MySQL server often fails. Delete ENGINE = ndbcluster from each PARTITION block before execution. If the goal is to use NDB, connect to a MySQL Cluster instance that supports those attributes.

When migrating from Oracle or PostgreSQL, partition scripts may include TABLESPACE directives. Translate them to MySQL by creating tablespaces first, then assigning partitions with ALTER TABLE ... ALTER PARTITION ... TABLESPACE statement.

Best Practices to Avoid This Error

Validate DDL in a staging database before production rollout. Lint scripts for reserved partition attributes. Maintain separate templates for engines that support extra attributes like NDB or InnoDB.

Adopt Galaxy's modern SQL editor to surface syntax warnings early. Galaxy highlights unsupported partition keywords contextually and suggests engine-specific alternatives, reducing deployment errors.

Related Errors and Solutions

Error 1493 (ER_PARTITION_ENGINE) indicates an engine that does not handle partitions. Switch the storage engine or drop partition clauses to resolve it.

Error 1502 (ER_PARTITION_CLAUSE_ON_NONPARTITIONED) occurs when a partition clause is used on a table not defined as partitioned. Add PARTITION BY or drop the clause to fix.

Common Causes

Including ENGINE inside PARTITION clause

ENGINE is a table-level option; placing it in a partition definition triggers ER_PART_STATE_ERROR.

Using NODEGROUP in non-NDB environments

NODEGROUP applies only to NDB Cluster. Other engines reject it.

Adding TABLESPACE per partition

TABLESPACE must be assigned through ALTER PARTITION, not during CREATE TABLE.

Legacy scripts with STORAGE or COMMENT options

Those options are deprecated for partitions and cause the error in modern MySQL versions.

Related Errors

Error 1493 ER_PARTITION_ENGINE

Raised when the chosen engine does not support partitioning.

Error 1502 ER_PARTITION_CLAUSE_ON_NONPARTITIONED

Occurs when a partition clause appears on a non-partitioned table.

Error 1517 ER_PARTITION_FUNCTION_IS_NOT_ALLOWED

Signals that the partitioning function is invalid for the column type.

FAQs

Can I set ENGINE per partition in MySQL?

No. ENGINE is a table-level property. Setting it inside a partition block causes ER_PART_STATE_ERROR.

Does InnoDB support NODEGROUP?

NODEGROUP is only for NDB Cluster. InnoDB will reject it with error 1522.

How can Galaxy help prevent this error?

Galaxy flags unsupported partition options during editing and offers engine-aware fixes, reducing deployment time.

Which MySQL versions raise this error?

Error 1522 appears in MySQL 5.1 and later whenever unsupported partition state attributes are used.
