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

if you can't or don't want to set the autoincrement property of the id, you can set value for the id for each row, like this:

INSERT INTO role (id, name, created)
SELECT 
      (select max(id) from role) + ROW_NUMBER() OVER (ORDER BY name)
    , name
    , created
FROM (
    VALUES 
      ('Content Coordinator', GETDATE())
    , ('Content Viewer', GETDATE())
) AS x(name, created)
