I've got a lot of tables that I want to fill with a missing data value when the entity is NULL. I really don't want to do this one column at a time. By using the FCOUNT() function I can get the number of fields, and the FIELD() function I can get the field name. How can I use this to then test if the value of column returned by FIELD() is null, and then fill it with the appropriate missing data value?

thanks
