David,
insert into companies (company_nbr,company_name,industry,status) values
(DEFAULT,'new company name','Industry','Opportunity')
With DEFAULT as the company_nbr why can't the company_name not have a value?

I changed the company_name for all company_nbr using the 'new company name'
for all rows with 'Industry' in that column.

Then I cannot use the sequence for adding new rows in the table and I must
manually enter each PK number?

Yes, that's the theory. It didn't work for me and why it didn't is what I
want to understand.
