MySQL Error 3559: Invalid Option Value in Function
Description
MySQL Error 3559 occurs when a function is called with an option (parameter) that has an invalid value. This typically happens when SQL statements provide a value that does not match the expected data type, is outside the permissible range, or has an incorrect format for the specified function option.
Error Message
Invalid value '%s' for option '%s' in function '%s'.
Known Causes
3 known causesIncorrect Data Type
An option value provided to a function does not match the expected data type, such as using a string where an integer is required.
Invalid Range or Enumerated Value
The supplied value for an option is outside the permissible minimum/maximum range or is not one of the allowed enumerated values for that option.
Malformed Option Value Syntax
A string value provided for an option does not conform to the expected syntax or format required by the function (e.g., an improperly formatted date string).
Solutions
3 solutions available1. Correct Function Argument Syntax easy
Ensure function arguments are correctly formatted and valid for the specific function being used.
1
Identify the function and the option that is causing the error. The error message provides this information (e.g., `Invalid value '%s' for option '%s' in function '%s'`).
2
Consult the MySQL documentation for the specific function. Look up the expected syntax and valid values for the option that is reported as invalid.
https://dev.mysql.com/doc/3
Modify your SQL query or stored procedure to use the correct value for the option. Pay close attention to data types, case sensitivity (if applicable), and allowed characters.
-- Example: Correcting a potential issue with a string option
-- Original (potentially incorrect):
-- SELECT some_function('invalid_option_value', 'some_other_arg');
-- Corrected (based on documentation):
SELECT some_function('valid_option_value', 'some_other_arg');2. Verify Data Type Compatibility medium
Confirm that the data type of the value passed to the function option matches what the function expects.
1
Examine the function call and the specific option that is causing the error. Note the data type of the value you are providing.
2
Check the MySQL documentation for the function to determine the expected data type for that option. Common types include strings, integers, booleans, or specific enumerated values.
3
If there's a mismatch, cast or convert the provided value to the correct data type. This might involve using `CAST()`, `CONVERT()`, or ensuring the literal value is formatted correctly (e.g., enclosing strings in quotes).
-- Example: Passing an integer where a string is expected
-- Original:
-- SELECT some_function(123, 'some_arg');
-- Corrected:
SELECT some_function(CAST(123 AS CHAR), 'some_arg');
-- Example: Passing a boolean value incorrectly
-- Original:
-- SELECT some_function('NO', 'some_arg'); -- 'NO' might not be recognized
-- Corrected:
SELECT some_function(0, 'some_arg'); -- Assuming 0 is valid for FALSE3. Review System Variables and Configuration advanced
Some function options might be influenced by MySQL system variables or server configuration settings.
1
Identify if the problematic function option is known to be affected by specific MySQL system variables. The error message might hint at this, or it might require looking at the function's implementation or related documentation.
2
Check the current values of relevant system variables using `SHOW VARIABLES LIKE 'variable_name%';` or by querying the `performance_schema.global_variables` table.
SHOW VARIABLES LIKE 'lower_case_table_names%'; -- Example variable3
If a system variable is set to an invalid or unexpected value that could affect the function's interpretation of the option, adjust it. This might require modifying the `my.cnf` (or `my.ini`) configuration file and restarting the MySQL server, or using `SET GLOBAL variable_name = value;` for dynamic variables (though this is less common for fundamental option validation).
-- Example: If a function's behavior depends on case sensitivity controlled by lower_case_table_names
-- This is a complex scenario and requires careful consideration of impact.
-- my.cnf edit example (requires restart):
-- [mysqld]
-- lower_case_table_names = 1
