<p>The error appears when a CREATE TABLE statement specifies an option that the chosen storage engine does not support.</p>
<p>MySQL Error 1478: ER_ILLEGAL_HA_CREATE_OPTION occurs when a CREATE TABLE clause uses an option unsupported by the selected storage engine. Pick a compatible option or switch to a storage engine that supports it to resolve the problem.</p>
Table storage engine '%s' does not support the create
Error 1478 fires when you run CREATE TABLE (or ALTER TABLE ... ENGINE=...) with a clause that the target storage engine cannot process. MySQL immediately stops the statement and returns: "Table storage engine '%s' does not support the create option '%s'."
This message highlights a mismatch between table options such as PARTITION BY, ROW_FORMAT, KEY_BLOCK_SIZE or DATA DIRECTORY and the capabilities of engines like InnoDB, MyISAM, or MEMORY. Fixing the mismatch lets the command succeed.
Ignoring the error leaves your table uncreated or unaltered, blocking deployments, migrations, or application features that depend on the table. Understanding the limitation prevents repeated failures and speeds up development pipelines.
The error always stems from specifying an engine-unsupported clause. For example, using PARTITION BY with MyISAM in MySQL 5.7 triggers the error because partitioning is only available for InnoDB in that version.
Another frequent cause is requesting ROW_FORMAT=COMPRESSED on a table defined with the MEMORY engine, which lacks compression support. Listing each mismatch in the error text guides you to the exact option that needs correction.
First, choose an engine that supports your desired options. If you must partition, switch to InnoDB. If you need a MEMORY table, drop unsupported clauses such as ROW_FORMAT. Alternatively, keep your engine and remove or change the conflicting option.
After adjusting the statement, rerun it to verify success. Always test in a staging environment before production deployment.
Deploying an archive table with ROW_FORMAT=COMPRESSED but ENGINE=MyISAM fails. Replace ENGINE=MyISAM with ENGINE=InnoDB or remove the compression clause.
Creating a high-speed temp table with ENGINE=MEMORY and KEY_BLOCK_SIZE=8 fails because MEMORY does not support KEY_BLOCK_SIZE. Drop the clause or choose ENGINE=InnoDB.
Review engine documentation before writing DDL. Validate options using SHOW ENGINE... and INFORMATION_SCHEMA. Automate schema checks in CI pipelines. In Galaxy, snippets flag invalid clauses in real time and AI Copilot suggests compatible engines.
ER_CANT_CREATE_TABLE (1005) indicates generic create failures. ER_NOT_SUPPORTED_YET (1235) appears when the server itself lacks a feature. Both can surface during similar DDL operations and require reviewing engine capabilities and server version.
MyISAM and MEMORY cannot be partitioned in recent MySQL versions. Any PARTITION BY clause on those engines triggers Error 1478.
ROW_FORMAT=COMPRESSED and KEY_BLOCK_SIZE are InnoDB-only features. Using them with MEMORY or CSV fails.
Engines like ARCHIVE do not allow FULLTEXT or SPATIAL indexes. Adding such indexes inside CREATE TABLE causes the error.
These clauses are not honored by InnoDB file-per-table. Including them leads to Error 1478.
A broad create failure that may arise from foreign-key or engine issues.
Triggered when the server version lacks a requested feature, such as check constraints in MySQL 5.6.
Appears when a column default is invalid for its data type or SQL mode.
No. MySQL aborts the statement. Remove or replace the clause instead.
In MySQL 5.7 and 8.0, only InnoDB supports full partitioning features.
Sometimes. Newer versions may extend engine capabilities, but engine limitations still apply.
Galaxy's AI Copilot validates DDL as you type, flags engine-option mismatches, and recommends compliant syntax.
