You have to use ALTER TABLE, here is example:

CREATE TABLE Foo (
keycol INT NOT NULL PRIMARY KEY);

ALTER TABLE Foo
ADD datacol VARCHAR(10) NOT NULL
CONSTRAINT df_datacol DEFAULT 'N/A';

INSERT INTO Foo (keycol) VALUES(1);

SELECT keycol, datacol
FROM Foo;

DROP TABLE Foo;

More details on ALTER TABLE:
