Description

Error 1584 indicates that a stored function was called with arguments that do not match its defined signature. This typically occurs when the number, data types, or order of the parameters provided in the function call are incorrect.

💬

Error Message

Incorrect parameters in the call to stored function '%s'

🔍

Known Causes

4 known causes

⚠️

Mismatched Argument Count

The number of arguments supplied in the function call does not correspond to the number of parameters defined for the stored function.

⚠️

Data Type Mismatch

One or more arguments passed to the function have a data type that is incompatible with the corresponding parameter in the function's definition.

⚠️

Incorrect Argument Order

Arguments are provided in an order different from the sequence defined for the parameters in the stored function, leading to incorrect value assignments.

⚠️

Stored Function Redefinition

The definition of the stored function (e.g., parameter count, types) was altered after the calling code was written, creating an incompatibility.

Solutions

4 solutions available

1. Verify Function Signature and Call Arguments easy

Ensure the number and types of arguments passed to the stored function match its definition.

1

Identify the stored function being called. The error message will usually contain the function name in the '%s' placeholder.

2

Retrieve the definition of the stored function using `SHOW CREATE FUNCTION`.

SHOW CREATE FUNCTION your_database_name.your_function_name;

3

Carefully compare the parameters defined in the `CREATE FUNCTION` statement with the arguments being passed in your SQL query or application code.

4

Adjust the number of arguments or their data types in the function call to precisely match the function's signature. For example, if the function expects an INTEGER and you're passing a VARCHAR, you might need to cast it.

SELECT your_function_name(CAST(your_variable AS SIGNED INTEGER));

2. Check for Missing or Extra Arguments easy

A common cause is providing too few or too many arguments when calling the function.

1

Examine the `CREATE FUNCTION` statement for the exact number of parameters it requires.

2

Review your SQL query or application code where the function is invoked. Count the number of values you are passing as arguments.

3

Add or remove arguments in your function call to match the expected count. If a parameter is optional and has a default value, ensure you are either providing a value or relying on the default correctly.

-- If function expects 2 args and you're calling with 1:
SELECT your_function_name(arg1, arg2);

-- If function expects 2 args and you're calling with 3:
SELECT your_function_name(arg1, arg2);

3. Review Data Type Mismatches medium

Ensure the data types of arguments passed to the function align with the defined parameter types.

1

Using `SHOW CREATE FUNCTION`, note the precise data type for each parameter of the stored function.

SHOW CREATE FUNCTION your_database_name.your_function_name;

2

Examine the data types of the variables or literals you are passing as arguments in your function call.

3

If there's a mismatch, use explicit casting to convert the argument to the expected data type. MariaDB has a rich set of casting functions.

-- Example: Function expects INT, you're passing VARCHAR
SELECT your_function_name(CAST(your_varchar_column AS SIGNED INTEGER));

-- Example: Function expects DATE, you're passing DATETIME
SELECT your_function_name(DATE(your_datetime_column));

4

Consider if implicit type conversion by MariaDB is failing or behaving unexpectedly. Explicit casting is often more reliable.

4. Recreate the Stored Function medium

If the function definition is corrupted or if subtle issues persist, recreating it can resolve the problem.

1

Backup the current function definition. This is crucial in case the recreation process fails or introduces new issues.

SHOW CREATE FUNCTION your_database_name.your_function_name INTO OUTFILE '/tmp/your_function_backup.sql';
-- Or, copy the output of SHOW CREATE FUNCTION to a file manually.

2

Drop the existing stored function.

DROP FUNCTION IF EXISTS your_database_name.your_function_name;

3

Review the backed-up `CREATE FUNCTION` statement for any syntax errors or inconsistencies. Correct them if found.

4

Recreate the stored function using the corrected `CREATE FUNCTION` statement.

-- Paste your corrected CREATE FUNCTION statement here.

5

Test the function call again after recreation.
