MySQL raises ER_INNODB_NO_FT_USES_PARSER when you try to create a FULLTEXT index with a custom PARSER clause on an InnoDB table, which is not supported.
ER_INNODB_NO_FT_USES_PARSER occurs because InnoDB does not allow the PARSER clause in CREATE FULLTEXT INDEX. Remove the PARSER option or switch to an ENGINE that supports it, and the statement will run successfully.
ER_INNODB_NO_FT_USES_PARSER
Error 1865 appears when a CREATE FULLTEXT INDEX or ALTER TABLE ... ADD FULLTEXT statement includes the PARSER option against an InnoDB table. Starting from MySQL 5.7.2, InnoDB supports built-in full-text indexing but disallows user-defined parsers, triggering this error.
The SQL state is HY000 (general error), which signals that the request violates an InnoDB limitation rather than a syntax problem.
The error surfaces immediately after MySQL parses the CREATE or ALTER command. The server stops execution before any data change occurs, so rolling back is unnecessary.
It can also appear during mysqldump restores if legacy scripts contain PARSER clauses intended for MyISAM tables.
Failing to build the index degrades text-search performance and may block application deployments. Addressing the issue ensures predictable release pipelines, especially in CI/CD environments.
The primary cause is the combination of ENGINE=InnoDB with the PARSER clause. InnoDB ignores custom parsers for full-text indexes for stability and transactional consistency.
Another trigger is an implicit engine mismatch: a table converted from MyISAM to InnoDB still contains old DDL in migration scripts that reference PARSER.
Remove the PARSER clause and rely on the default InnoDB full-text parser. If you need a custom parser, convert the table to MyISAM or migrate data into a separate MyISAM side table dedicated to search.
Galaxy users can detect the PARSER keyword with the editor’s linting rules and auto-rewrite the statement before execution, preventing runtime errors.
Legacy migration scripts - Edit the file and delete the PARSER argument.
Third-party CMS install - Switch storage engine to MyISAM for the affected table or patch the installer.
Audit DDL scripts for PARSER usage when converting tables to InnoDB. Incorporate CI checks that run EXPLAIN on DDL and ensure compatibility.
In Galaxy, enable query review workflows so senior engineers endorse compliant DDL before it reaches production.
Error 1214 ER_NOT_SUPPORTED_YET - Triggered by unsupported foreign keys in partitioned tables.
Error 1210 ER_DDL_LOG_ERROR - Appears when InnoDB cannot write DDL logs; often fixed by disk space checks.
Old scripts written for MyISAM include PARSER to reference ngram or other plugins. When run on upgraded InnoDB tables they fail.
Examples found online may target MyISAM and are pasted into an InnoDB environment without adjustment.
ORMs or migration tools may template PARSER when generating full-text indexes, ignoring the storage engine.
Raised when attempting unsupported operations like foreign keys on partitioned tables.
Occurs if the chosen storage engine is disabled in the server configuration.
Indicates a failure to write internal DDL logs during an ALTER operation.
No. As of MySQL 8.0.36 InnoDB still blocks custom parsers. You must switch engines or externalize search.
Yes, if you relied on n-gram parsing for CJK languages. Consider MySQL 8.0 ngram parser plugin with MyISAM or external search systems like Elasticsearch.
MyISAM lacks transactions but offers faster full-text search. Evaluate workload and consider hybrid architecture.
Galaxy flags unsupported clauses, suggests fixes, and lets teams endorse compliant migrations so the error never reaches production.
