The parameter list must correspond to the parameter style in the CREATE FUNCTION statement for the UDF.

Use parameter style SQL to allow a UDF to pass null values for the result or for input arguments; otherwise, use parameter style TD_GENERAL.

When you use parameter style SQL, you must define indicator parameters for the result and for each parameter.
