Description

This error indicates that a built-in MariaDB function was called with an incorrect number of arguments. It typically occurs when a SQL statement provides either too many or too few parameters than the native function expects, preventing the query from executing.

💬

Error Message

Incorrect parameter count in the call to native function '%s'

🔍

Known Causes

3 known causes

⚠️

Missing Required Parameters

A native function was invoked without providing all of its mandatory arguments, leading to an incomplete function call.

⚠️

Too Many Parameters Provided

The native function received more arguments than its defined signature allows, resulting in an excess of input.

⚠️

Misunderstanding Function Signature

The SQL query or application code misinterprets the expected number of parameters for a specific native function.

Solutions

4 solutions available

1. Verify Function Signature and Usage easy

Ensure the function is called with the correct number and types of arguments as defined by its signature.

1

Identify the specific native function mentioned in the error message (e.g., '%s').

ERROR MESSAGE: Incorrect parameter count in the call to native function 'SUBSTRING'

2

Consult the MariaDB documentation for the exact signature of that function. Pay close attention to the number of expected parameters and their data types.

SELECT argument_list FROM information_schema.routines WHERE routine_name = 'SUBSTRING';

3

Review your SQL query or stored procedure where the function is being called. Count the number of arguments you are providing.

SELECT SUBSTRING('abcdef', 2) FROM dual; -- Incorrect if SUBSTRING expects 3 arguments
SELECT SUBSTRING('abcdef', 2, 3) FROM dual; -- Correct if SUBSTRING expects 3 arguments

4

Adjust the number of arguments in your call to match the function's signature. If a parameter is optional, ensure you are not omitting it incorrectly or providing too many.

UPDATE your_table SET column = NEW_VALUE WHERE some_condition;

2. Check for Typographical Errors in Function Names easy

A simple typo in the function name can lead to MariaDB interpreting it as an unknown function, triggering this error.

1

Carefully examine the function name in your query or code. Compare it character by character with the correct function name.

SELECT CONCATENATE('Hello', ' ', 'World') FROM dual; -- Typo, should be CONCAT

2

Refer to the MariaDB documentation or a reliable reference to confirm the correct spelling of the function you intend to use.

3

Correct any spelling mistakes in your SQL statements or application code that calls the function.

SELECT CONCAT('Hello', ' ', 'World') FROM dual; -- Corrected

3. Review Custom User-Defined Functions (UDFs) medium

If the error points to a user-defined function, verify its definition and how it's being called.

1

Determine if the function mentioned in the error is a built-in MariaDB function or a custom User-Defined Function (UDF).

SELECT routine_type, routine_name FROM information_schema.routines WHERE routine_name = 'your_custom_function_name';

2

If it's a UDF, examine its definition in the `mysql.general_log` or `mysql.slow_log` if logging is enabled, or directly query the `information_schema.routines` table.

SELECT routine_definition FROM information_schema.routines WHERE routine_name = 'your_custom_function_name' AND routine_type = 'FUNCTION';

3

Compare the number of parameters expected in the UDF's definition with the number of arguments provided in the call.

CREATE FUNCTION my_add(a INT, b INT) RETURNS INT RETURN a + b;
SELECT my_add(5); -- Incorrect parameter count

4

Modify the UDF definition or the call to the UDF to ensure parameter counts match.

SELECT my_add(5, 10); -- Corrected call

4. Investigate MariaDB Version Compatibility medium

Some functions might have different parameter requirements or might not exist in older MariaDB versions.

1

Determine the exact MariaDB version you are running.

SELECT VERSION();

2

Check the MariaDB documentation for the specific function you are using and its parameter requirements for your MariaDB version.

Visit https://mariadb.com/kb/en/ and search for the function and your version.

3

If the function's behavior or parameter count has changed between versions, you may need to update your queries to align with the current version's expectations.

Example: A function that previously took 1 argument might now require 2 in a newer version.

4

Consider upgrading your MariaDB instance if you are using a very old version and encountering issues with newer function syntax.

Consult MariaDB upgrade guides for your specific version.
