Why is SQL server throwing this error: Cannot insert the value NULL into column 'id'?

Question

I\'m using the following query:

INSERT INTO role (name, created) VALUES (\'Content Coordinator\', GETDATE()), (\'Content Viewer\', GETDATE())

Answer 1

You can insert a value manually in the ID column (here I call it "PK"):

insert into table1 (PK, var1, var2)
values ((select max(PK)+1 from table1), 123, 456)
