The EXTFNAPIV4_DESCRIBE_PARM_NAME attribute indicates the parameter name. Used in a describe_parameter_set scenario.
char[]
The name of a parameter to a UDF.
If the UDF sets this property, the server compares the value with the name of the parameter supplied in the CREATE PROCEDURE statement. If the two values do not match, the server returns an error. This allows the UDF to ensure the CREATE PROCEDURE statement has the same parameter names as the UDF is expecting.
On success, returns the length of the parameter name.
