MySQL Error 1307: Failed to Create Stored Program

📦 MySQL
📋

Description

MySQL Error 1307 indicates a failure to create a stored program, such as a stored procedure, function, trigger, or event. This error commonly occurs when the SQL statement for creating the object encounters issues related to syntax, user permissions, or server configuration settings.

Known Causes

4 known causes
⚠️
Invalid Program Syntax
The SQL definition within the stored program (procedure, function, trigger, or event) contains syntax errors or references non-existent objects.
⚠️
Insufficient User Privileges
The MySQL user attempting to create the stored program lacks the necessary `CREATE ROUTINE`, `CREATE TRIGGER`, or `CREATE EVENT` privileges for the target database.
⚠️
Server Configuration Restrictions
MySQL server variables, such as `log_bin_trust_function_creators`, are configured to restrict the creation of certain stored programs, especially in replication environments.
⚠️
Non-existent Database/Schema
The database or schema specified in the `CREATE` statement does not exist, or the user does not have access to it.

Solutions

3 solutions available

1. Verify Stored Program Permissions easy

Ensure the user executing the CREATE statement has the necessary privileges.

1
Connect to your MySQL server as a user with administrative privileges (e.g., root).
2
Check the privileges granted to the user attempting to create the stored program. They need the `CREATE ROUTINE` privilege.
SHOW GRANTS FOR 'your_user'@'your_host';
-- If CREATE ROUTINE is missing, grant it:
GRANT CREATE ROUTINE ON your_database.* TO 'your_user'@'your_host';
FLUSH PRIVILEGES;
3
Re-attempt to create the stored program after verifying or granting the necessary permissions.

2. Check for Syntax Errors in the Stored Program Definition easy

A malformed stored program definition is a common cause of this error.

1
Carefully review the `CREATE PROCEDURE` or `CREATE FUNCTION` statement for any syntax errors. Pay close attention to:
- Delimiters (especially if using `DELIMITER` outside of a stored procedure context).
- Commas, parentheses, and keywords.
- Data types and parameter definitions.
2
If you are using a tool that handles delimiters automatically (like MySQL Workbench), try executing the statement directly in the MySQL client to see if the delimiter handling is the issue.
3
Simplify the stored program to its most basic form to isolate potential syntax issues. For example, create an empty procedure and then gradually add complexity.
DELIMITER //
CREATE PROCEDURE simple_test()
BEGIN
  -- Empty body
END //
DELIMITER ;

-- Then add logic step-by-step.

3. Investigate Server Configuration Limits medium

Certain server configurations might prevent the creation of very complex or large stored programs.

1
Check the MySQL server's `max_allowed_packet` setting. If the stored program definition is very large, it might exceed this limit.
SHOW VARIABLES LIKE 'max_allowed_packet';
2
If `max_allowed_packet` is too small, increase it. This can be done temporarily or permanently.

**Temporary (until server restart):**
sql
SET GLOBAL max_allowed_packet = 16777216; -- Example: 16MB


**Permanent (edit my.cnf/my.ini):**
Add or modify the `max_allowed_packet` line under the `[mysqld]` section:
ini
[mysqld]
max_allowed_packet = 16M


Remember to restart the MySQL server after making permanent changes.
3
Consider other server limits that might indirectly affect stored program creation, such as memory allocation or thread limits, although these are less common causes for this specific error message.
