Re: Setting a field to default if blank value

Robert,

I use a default value on columns that I define as not null and want particular data to be inserted if no value is
supplied. After you create your table a simple alter statement is all you need: 
alter table table_name alter column column_name set default ' ';

Hope this helps

Yes, they are strings (varchar). Know the best way to handle it?
