<p>MySQL throws error 1458 (ER_SP_WRONG_NAME) when a stored routine, function, or trigger name contains illegal characters or exceeds length rules.</p>
<p>MySQL Error 1458: ER_SP_WRONG_NAME occurs when the server encounters an invalid routine name during CREATE, ALTER, or DROP statements. Review the identifier - remove spaces, punctuation, or reserved words - then rerun the statement to resolve the issue.</p>
Incorrect routine name '%s'
Error 1458 arises when MySQL rejects a stored procedure, function, trigger, or event name because it violates identifier rules.
The server checks names during CREATE, ALTER, DROP, and CALL statements. If the identifier contains spaces, starts with a digit, uses reserved keywords, or exceeds 64 characters, MySQL returns ER_SP_WRONG_NAME with message "Incorrect routine name '%s'".
Fixing the error is crucial because calls to an invalidly named routine will fail, breaking application workflows and scheduled jobs.
Most cases stem from typos such as including hyphens, dots, or spaces inside the routine identifier.
Developers sometimes paste code from other platforms that wrap names in backticks incorrectly or mix case sensitivity in a lower_case_table_names environment.
The error also appears when attempting to create a routine whose name matches an existing table or view, leading to a conflict.
First, validate the identifier against MySQL rules: 1-64 characters, alphanumeric or underscore, start with a letter or underscore, and avoid reserved words.
Second, rename the routine in the CREATE or ALTER statement. Use SHOW FUNCTION STATUS or SHOW PROCEDURE STATUS to confirm the chosen name is free.
Finally, rerun the DDL. If the old invalid routine was partially created, DROP ROUTINE IF EXISTS before recreating it.
Scenario: Using hyphens like get-user-data. Solution: rename to get_user_data and recreate.
Scenario: Copying Excel column header "Total Sales" as a function name. Solution: change to total_sales and update all CALL statements.
Scenario: Migration tools prepend schema names with dots, producing store.sales.calc. Remove dots or wrap each part with the schema separator.
Adopt a strict naming convention: lowercase, snake_case, and prefix routine types (sp_, fn_).
Automate linting with CI scripts or Galaxy's AI copilot to flag invalid identifiers before deployment.
Document reserved words and enforce code review checklists to catch naming conflicts early.
ER_BAD_DB_ERROR - database does not exist; verify schema name.
ER_NO_SUCH_PROCEDURE - procedure not found; check routine name spelling.
ER_SP_ALREADY_EXISTS - routine exists; choose a unique name.
Hyphens, dots, spaces, or special symbols inside the routine name break MySQL identifier rules.
Naming a routine SELECT, ORDER, or any reserved word forces MySQL to reject the statement.
Identifiers longer than 64 characters exceed MySQL's limit and return ER_SP_WRONG_NAME.
Routine names starting with a number are invalid and trigger the error.
Raised when creating a routine with a name that already exists in the schema.
Occurs when calling or dropping a routine that MySQL cannot find.
Indicates insufficient privileges to access or modify a stored routine.
MySQL allows up to 64 characters for procedure, function, trigger, and event names.
No. Even with backticks, spaces in routine names are disallowed and will raise ER_SP_WRONG_NAME.
Yes. TRIGGER and EVENT identifiers follow the same naming rules and can return ER_SP_WRONG_NAME.
Galaxy's context aware AI autocompletes valid identifiers and warns when a proposed name violates MySQL rules, preventing errors before execution.
