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

As id is PK it MUST be unique and not null. If you do not mention any field in the fields list for insert it'll be supposed to be null or default value. Set identity (i.e. autoincrement) for this field if you do not want to set it manualy every time.
