CREATE VIEW

CREATE VIEW

The table games shows the year and the city hosting the Olympic Games.

games

yr	city
2004	Athens
2008	Beijing

schema:scott

 DROP TABLE games;
DROP TABLE old_games;
DROP TABLE og

 CREATE TABLE games(
  yr INTEGER PRIMARY KEY,
  city VARCHAR(20));
INSERT INTO games VALUES (2000,'Sydney');
INSERT INTO games VALUES (2004,'Athens');
INSERT INTO games VALUES (2008,'Beijing');
INSERT INTO games VALUES (2012,'London');

The CREATE VIEW names a SELECT query. That query may be used as if it were a table in many contexts. In this example the VIEW old_games shows those games before 2006.

CREATE VIEW og AS
  SELECT yr,city FROM scott.games
   WHERE yr<2006;
SELECT * FROM og;

CREATE VIEW og AS
  SELECT yr,city FROM games
   WHERE yr<2006;
SELECT * FROM og;
