Its a good idea for some of our tables actually, some of the smaller ones anyway, but some bigger tables we use have loads of NULL values, which im understanding is pretty bad in a database anyway. The only way I can see to overcome them is do a mass table update to change their values in the table to non-null, like above (which is time consuming and doesnt seem ideal to be honest), or change the field to allow nulls and do what you said. The only issue I can see with this is the way MSSQL exports the data, because it just gives you ”,” for nulls instead of something useful such as NULL.. but im starting to see we could benifit from the info, so muchly apreciated!
