<p>Error 1582 occurs when a MySQL built-in function is called with an incorrect number of arguments.</p>
<p>MySQL Error 1582: ER_WRONG_PARAMCOUNT_TO_NATIVE_FCT appears when a built-in function receives too few or too many parameters. Verify the function signature, match the exact argument count, and rerun the statement to resolve the issue.</p>
Incorrect parameter count in the call to native function
MySQL throws error 1582 (SQLSTATE 42000) with the message "Incorrect parameter count in the call to native function" when a built-in function is invoked with the wrong number of arguments.
The server checks the argument list during parsing. If the supplied count does not match the expected signature, it aborts execution to prevent unpredictable results.
Mismatched argument counts trigger the fault. Sending three parameters to SUBSTRING or only one to ROUND breaks the syntax rules enforced by MySQL.
Typos, misplaced commas, and dynamic SQL that builds function calls at runtime frequently introduce the extra or missing parameters.
Read the official documentation for the function in question, count the required parameters, and adjust your call. Remove surplus commas, add missing arguments, or switch to an alternative function if the signature does not fit your need.
SUBSTRING expects either 2 or 3 parameters. Calling SUBSTRING(col) fails with 1582. Add the starting position and length to fix the query.
ROUND(value, places) requires two arguments. Round(price) triggers the error. Supply the decimal places or drop ROUND entirely if rounding is unnecessary.
Always reference the function signature before use. Enable strict SQL mode so that MySQL surfaces errors early.
Editors like Galaxy highlight function prototypes and autocomplete arguments, reducing the chance of mismatch in the first place.
Error 1064 signals general SQL syntax issues that can include bad function calls. Error 1210 indicates an illegal mix of collations when arguments differ by charset. Review each error's specific message to guide debugging.
Supplying more parameters than the function definition supports causes error 1582 immediately.
Omitting required parameters leaves MySQL unable to evaluate the function and raises the same error.
Extra commas or missing parentheses create the appearance of additional arguments.
String concatenation that builds queries on the fly often miscounts parameters.
General syntax error often linked to incorrectly formed function calls.
Illegal mix of collations in function arguments, differing from pure count issues.
FUNCTION does not exist, triggered when a user-defined function name is mistyped.
No. It only applies to native MySQL functions. User-defined functions raise a different error when misused.
Yes. STRICT mode forces MySQL to reject statements with mismatched parameter counts immediately.
Galaxy’s autocomplete displays function signatures, alerting you when you miss or add parameters.
No. Argument count validation is mandatory for native functions and cannot be bypassed.
