I think the approach Hugo suggested may work. Since I am using this column as a placeholder the field value will be set according to the business logic of the program (I know that me and logic do not go together well <g>). Most of the values will be set to 0 or 1. But there could be a case where the value will be NULL and this is why I want to allow NULLs.
Thank you, Hugo.
