MySQL throws error 3110 when a statement references a feature disabled or not compiled into the running server build.
ER_FEATURE_NOT_AVAILABLE (error 3110) means your MySQL build lacks the requested feature. Remove the unsupported clause or install a server compiled with that feature to resolve the issue.
ER_FEATURE_NOT_AVAILABLE
MySQL raises ER_FEATURE_NOT_AVAILABLE when the running server binary was compiled without a feature that your SQL statement tries to use. The server stops parsing and returns SQLSTATE HY000 and error code 3110.
Typical examples include statements referencing compression algorithms, thread pool scheduling, or enterprise plugins that are disabled in community builds. The error was introduced in MySQL 5.7.6 to block unsupported syntax early.
The error is triggered at parse time when MySQL spots a keyword or clause wrapped in a compile time guard that is off in your build.
Copying documentation examples for enterprise only features, restoring dumps from a server with different compile flags, or using MySQL upgraded without matching plugins also cause the failure.
Identify the feature named in the message, then either remove the option or alter the statement so it no longer requires that functionality.
If the feature is required, migrate to a distribution compiled with it. You can download MySQL Enterprise, use Percona Server, or build from source with the needed CMake flag set.
Creating a compressed MyISAM table fails on a build without myisam_compress. Remove ROW_FORMAT=COMPRESSED or switch server.
Installing audit_log plugin on community build fails with 3110. Replace the binary with one that includes the audit plugin.
Keep all environments on the same MySQL edition and version to maintain feature parity.
Run SHOW PLUGINS and review version_compile_os variables during CI to detect missing capabilities early. Galaxy can store these checks in shared queries for the team.
ER_UNKNOWN_STORAGE_ENGINE (1286) appears when a required storage engine is not loaded; install or enable the engine.
ER_UNSUPPORTED_EXTENSION (1109) indicates unknown table or column; correct the identifier or upgrade the server version.
Running the community edition but using enterprise only syntax triggers 3110.
The required storage engine or plugin was not built into the binary.
A rollback to an earlier or minimal build removed previously available features now referenced by stored code.
Raised when specified storage engine is unavailable. Install or load the engine to fix.
Occurs when server option prevents a statement, such as read only mode.
Triggered when a referenced plugin is not loaded. Install or load the plugin.
No. The server will not run the statement until the unsupported feature is removed or enabled.
Upgrading to a build that includes the required feature resolves it; upgrading to another minimal build will not.
The placeholder in the message shows the feature name. Consult the release notes for its compile flag or plugin.
Galaxy highlights MySQL errors inline and lets teams share fixed queries, ensuring unsupported syntax is caught during review.
