The function is always evaluated whether parameters are null at the time the function is to be called or not.

If the PARAMETER STYLE for the function is TD_GENERAL, nulls generate an exception condition.

This clause is optional and can only be specified once per function definition.

The default is CALLED ON NULL INPUT.
