Add a column with a default value to an existing table in SQL Server

Question

How can I add a column with a default value to an existing table in SQL Server 2000 / SQL Server 2005?

Answer 1

First create a table with name student:

CREATE TABLE STUDENT (STUDENT_ID INT NOT NULL)

Add one column to it:

ALTER TABLE STUDENT 
ADD STUDENT_NAME INT NOT NULL DEFAULT(0)

SELECT * 
FROM STUDENT

The table is created and a column is added to an existing table with a default value.
