A required CREATE TABLE option for the chosen storage engine is missing, so MySQL aborts the statement.
MySQL error 3014 ER_MISSING_HA_CREATE_OPTION occurs when a CREATE TABLE statement omits a mandatory option for the selected storage engine. Add the required CREATE option (for example, ROW_FORMAT or KEY_BLOCK_SIZE for InnoDB compressed tables) or switch to a compatible engine to resolve the issue.
ER_MISSING_HA_CREATE_OPTION
Error 3014 surfaces when a CREATE TABLE statement selects a storage engine that expects specific table options, but the statement leaves them out. MySQL validates engine-specific requirements before creating the table and raises ER_MISSING_HA_CREATE_OPTION if any mandatory option is absent.
The error was introduced in MySQL 5.7.2 to prevent silent misconfiguration of engines that depend on options such as ROW_FORMAT, KEY_BLOCK_SIZE, or DATA DIRECTORY. Fixing it is crucial because the table is never created and subsequent inserts or queries will fail.
The primary trigger is choosing an engine that mandates extra parameters while omitting them. InnoDB compressed or TempTable engines often require ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE.
Another cause is a plugin or custom engine that enforces proprietary options. When the parser cannot find those options in the CREATE statement, it stops with error 3014.
First, examine the engine documentation for mandatory options. Identify which option MySQL expects, then add it to the CREATE TABLE statement.
If you do not need the special engine feature, switch to a default engine like InnoDB without compression. This removes the requirement completely.
Developers enabling InnoDB compression without specifying ROW_FORMAT=COMPRESSED hit this error. Adding the missing ROW_FORMAT resolves it.
Users migrating from MyISAM to a plugin engine sometimes overlook required metadata options; revising the CREATE statement with those options fixes the issue.
Always review engine-specific documentation prior to deploying new storage engines or features. Document the required table options in migration scripts.
Use Galaxy's AI copilot to autocomplete engine-specific CREATE TABLE syntax. The editor flags missing options before execution, preventing runtime errors.
ER_UNKNOWN_STORAGE_ENGINE occurs when the engine itself is unavailable. Unlike 3014, this error happens before option validation.
ER_ILLEGAL_HA is raised when an engine is disabled. Solving 3014 focuses on options, while ER_ILLEGAL_HA requires enabling the engine or choosing another.
InnoDB tables that request KEY_BLOCK_SIZE without ROW_FORMAT=COMPRESSED trigger error 3014.
When specifying ROW_FORMAT=COMPRESSED you must also supply KEY_BLOCK_SIZE; omitting it will raise the error.
Third-party engines may introduce mandatory options like PAGE_SIZE or ENCRYPTION_KEY; missing any of them leads to the same error.
Raised when the specified engine is not loaded. Load the plugin or use a supported engine.
Occurs if the engine is disabled by the server. Enable it with --plugin-load or choose another engine.
Appears when row size exceeds the engine limit. Redesign columns or switch engines.
No. The SQL syntax is valid, but the engine requires extra options that are missing.
Only CREATE TABLE or ALTER TABLE operations fail. Existing tables remain unaffected.
The error exists from MySQL 5.7.2 onward for any engine that implements required options.
