Error 1307 indicates that MySQL could not store a new procedure, function, trigger, or event definition in the mysql system tables during a CREATE statement.
MySQL Error 1307: ER_SP_STORE_FAILED occurs when the server cannot write a new procedure, function, trigger, or event to the mysql system tables. Check routine name conflicts, DEFINER user existence, system-table integrity, and required privileges. Re-run CREATE after correcting privileges or repairing mysql.proc.
Failed to CREATE %s %s
MySQL throws ER_SP_STORE_FAILED with SQLSTATE HY000 when it fails to store a new stored procedure, function, trigger, or event in the mysql system tables during a CREATE statement.
The accompanying message “Failed to CREATE %s %s” identifies the object type and name that could not be saved. The server has rolled back the CREATE, so the routine is unavailable until the underlying problem is fixed.
Name conflicts happen first – attempting to create a routine, trigger, or event that already exists with the same schema and name produces a storage failure.
Missing or invalid DEFINER users prevent MySQL from writing the routine metadata because it cannot resolve the user identifier recorded in the DEFINER clause.
Corrupted or outdated system tables (mysql.proc before MySQL 8, mysql.routines in MySQL 8) block inserts, leading to ER_SP_STORE_FAILED.
Lack of SUPER or CREATE ROUTINE privilege on the target database stops MySQL from inserting the metadata row.
Disk-space shortages or read-only file systems stop the engine from persisting the new entry.
Confirm the routine does not already exist. Drop or rename duplicate objects before re-creating.
Verify the DEFINER user exists. Either create the user with CREATE USER or remove/adjust the DEFINER clause to CURRENT_USER.
Check privileges with SHOW GRANTS; grant CREATE ROUTINE, ALTER ROUTINE, and EXECUTE as required.
Repair system tables: run mysql_upgrade or mysqlcheck --repair mysql proc to rebuild damaged metadata tables.
Ensure the data directory has free space and correct read-write permissions, then retry the CREATE statement.
Duplicate routine name: Execute DROP PROCEDURE IF EXISTS db.myproc; then re-run CREATE PROCEDURE.
Missing DEFINER user after migration: Replace DEFINER='olduser' with DEFINER=CURRENT_USER in the CREATE definition.
Upgrade from MySQL 5.6 to 8.0: Run mysql_upgrade to convert mysql.proc to the new data dictionary.
Readonly replica: Enable --super-read-only=0 or connect to primary before creating routines.
Always check for existing routine names with INFORMATION_SCHEMA.ROUTINES before running CREATE statements.
Use role-based accounts and reference DEFINER=CURRENT_USER instead of hard-coding individual accounts.
Automate mysql_upgrade after version upgrades to keep system tables consistent.
Developers using Galaxy can run pre-commit checks and lint SQL definitions, catching duplicate names and missing privileges before pushing to production.
Error 1304 ER_SP_ALREADY_EXISTS: Triggered when a stored routine with the same name already exists. Drop or rename the routine.
Error 1548 ER_CANT_CHANGE_TX_ISOLATION: Raised when a routine modification needs a different isolation level. Change session isolation or wrap in autocommit.
Error 1418 ER_NO_SUCH_USER: Happens when DEFINER user is missing. Create the user or change the DEFINER clause.
A procedure, function, trigger, or event with the same name already exists in the schema.
The account specified in the DEFINER clause does not exist or lacks necessary privileges.
The mysql.proc (pre-8.0) or data dictionary tables are damaged or out of sync after an upgrade.
The caller lacks CREATE ROUTINE or SUPER privilege on the target database.
Read-only mounts or full disks block MySQL from persisting the routine metadata row.
Raised when attempting to create a routine that already exists. Resolve by dropping or renaming the existing routine.
Occurs when the DEFINER user specified in a routine does not exist. Create the user or modify the DEFINER clause.
Triggered when a CREATE TRIGGER statement conflicts with an existing trigger of the same name on the table.
Thrown when MySQL cannot change transaction isolation level while modifying or creating routines.
No. MySQL rolls back the CREATE statement. The routine is not available until you rerun CREATE successfully.
Older clients send legacy statements. Run mysql_upgrade to align system tables or use MySQL 8 client libraries.
Yes. Use DEFINER=CURRENT_USER or SQL SECURITY INVOKER so deployment scripts work across environments.
Galaxy’s linter warns about duplicate names and missing privileges before executing CREATE statements, reducing production failures.
