Informix Error -16356: Too many parameters passed to function function-name.

Cause and resolution

Too many parameters passed to function function-name.

Your argument list in a CALL command includes more parameters than the function is defined as receiving. If you are not sure how many parameters should be passed to the function, you can use a VIEW command to display the source code of the function.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-16356 fires when a CALL command's argument list has more parameters than the function is defined to take — per the official guidance.

  1. A CALL command with more parameters than the function accepts, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Remove the extra parameters, per the official guidance.
  2. Use VIEW to display the function's source code if unsure how many parameters it expects, per the official guidance.
Examples
A CALL command with too many parameters
> CALL myfunc(arg1, arg2, arg3)
Corrected
> CALL myfunc(arg1, arg2)
Diagnostic Checks
  1. Use VIEW on the function's source to confirm its expected parameter count.
