MySQL cannot save a new stored procedure, function, trigger, or event in the mysql system tables.
MySQL Error 1307: ER_SP_STORE_FAILED appears when the server cannot write a new stored procedure, function, trigger, or event into the mysql system tables. Check object name conflicts, permissions, and system table health, then recreate the routine after correcting those issues.
Failed to CREATE %s %s
MySQL raises error 1307 with message "Failed to CREATE %s %s" when it cannot save a new stored procedure, function, trigger, or event in the mysql system tables. The failure happens after parsing, so the definition is valid SQL but cannot be stored.
The problem surfaces on CREATE PROCEDURE, CREATE FUNCTION, CREATE TRIGGER, or CREATE EVENT statements.
The server tries to record the object in the mysql.routines or mysql.event meta-tables and fails, aborting the transaction.
Until resolved, you cannot deploy or alter affected routines, blocking application releases, automated jobs, and business logic inside the database. Ignoring the issue risks inconsistent environments and lost work.
Most failures trace back to privilege gaps, naming collisions, corrupted system tables, or filesystem problems.
Understanding these root causes lets you apply a precise remedy instead of trial-and-error fixes.
Begin with a privilege and existence check, then inspect system table integrity. If corruption is suspected, run mysqlcheck or mysql_upgrade. Finally, recreate or alter the routine once underlying issues are cleared.
Privileges missing on DEFINER accounts, duplicate routine names across databases, or lost upgrades after version changes are the most frequent triggers.
Each scenario has a targeted, repeatable fix described below.
Grant explicit CREATE ROUTINE and ALTER ROUTINE privileges, enforce naming conventions, automate integrity checks on mysql.* tables, and run mysql_upgrade after every server upgrade to prevent 1307 from resurfacing.
Errors 1304 (ER_PROC_CREATE_FAILED) and 1435 (ER_CANT_UPDATE_TABLE_IN_CREATE_TRIGGER) often appear in similar contexts. Reviewing their differences helps you troubleshoot faster when multiple errors coexist.
.
The DEFINER user or current session lacks CREATE ROUTINE or TRIGGER privilege on the database, so MySQL blocks the write to mysql.routines.
A procedure, function, or trigger with the same name already exists in the target schema, causing the metadata insert to violate a uniqueness constraint.
Tables such as mysql.routines or mysql.event are corrupted or out of sync after an upgrade, blocking any insert or update operations.
The underlying storage engine cannot write to disk due to full disk, read-only mount, or file-system quota limits, causing the store failure.
The routine definition uses a character set unsupported by the mysql system tables, leading to encoding errors during the insert.
.
No. Privilege gaps and name conflicts are more common. Check those first before assuming table corruption.
MySQL offers no FORCE option for CREATE ROUTINE. You must resolve underlying issues then recreate the object.
A restart only helps if the failure was due to transient file-system locks. Most cases require privilege or metadata fixes.
Galaxy’s AI copilot warns about duplicate routine names and missing privileges before execution, reducing the chance of hitting error 1307 in production.
