> There are four types of implementation of table-valued function:
> 1. FixedSchemaOutput. The output of the TVF is pre-defined.
> 2. InputSchemaForwardToOutput. The output schema of the TVF is the same as input schema.
> 3. InputSchemaForwardToOutputWithAppendedColumns. The output schema of the TVF is the same as input schema plus columns appended.
> 4. TemplatedTVF. Parameters of TVF are templated. (e.g. ANY TYPE, ANY TABLE, etc.)
