<p>Error 1584 indicates that the parameters supplied to a stored function do not match its definition.</p>
<p>MySQL Error 1584: ER_WRONG_PARAMETERS_TO_STORED_FCT occurs when the argument list used in a stored function call differs in number, order, or type from the function signature. Check the function definition, adjust the CALL or SELECT argument list, and retry the query to resolve the problem.</p>
Incorrect parameters in the call to stored function %s
MySQL Error 1584 (SQLSTATE 42000) signals that the parameters sent to a stored function do not match the function definition. Mismatches include wrong count, order, data type, length, or missing IN/OUT qualifiers, so MySQL aborts the call.
The error appears during compilation of a CALL or SELECT statement, inside prepared statements, during procedure execution, or while creating a view that invokes the function with incompatible arguments.
Unresolved parameter mismatches block queries, break application logic, and can halt deployments. Rapid fixes restore functionality and avoid cascading timeout errors.
Root triggers include extra or missing arguments, implicit type conversions that fail with strict SQL_MODE, different collations, or referencing renamed parameters after a schema change.
Locate the stored function definition with SHOW CREATE FUNCTION, compare each argument, adjust the calling statement, or alter the function. Re-test in a transaction to confirm the fix.
Applications that upgraded to STRICT mode need explicit casts. Migration scripts that reordered parameters require updating every stored call. CI pipelines should include unit tests that run CALLs with sample data.
Use named parameters in code generators, version functions in Git, validate calls during code review, and rely on Galaxy’s inline linting to flag mismatches before execution.
Errors 1414, 1415, and 1318 often surface when argument lists cross between procedures and functions. Their fixes follow similar compare-and-align steps.
Supplying fewer or more arguments than the function definition immediately triggers Error 1584.
Passing VARCHAR where INT is expected or vice versa fails when strict SQL_MODE is active.
A NOT NULL parameter receiving NULL violates the definition and raises the error.
Renaming or reordering parameters without updating every call site leaves old code calling the new signature.
Raised when a NOT NULL parameter receives NULL, often adjacent to 1584.
Occurs when an argument type is illegal for the procedure or function.
Reported when arguments for a function are incorrect in general, especially for UDFs.
No. Ignoring the error prevents the query from running and can mask deeper schema drift issues.
Yes. MySQL matches by position, not by name, so order must be exact.
CAST resolves type issues but not wrong counts. Always verify argument quantity first.
Galaxy’s editor inspects the function signature in real time and highlights calls with wrong argument lists before execution.
