I have a table that has a field that wants to be converted to allow null values.
I also have an existing program that performs a 'Select *' from the table into a data structure defined using ExtName(). The null capable field, is not referenced anywhere in the program, it is only ever being inserted into this data structure.
I am wondering what steps, if any, will I need to perform in order to ensure that this program will not break when a null value is inserted into this field.
