How To Create a New View?

You can create a new view based on one or more existing tables by using the "CREATE VIEW viewName AS selectStatement" statement as shown in the following script:

mysql> CREATE TABLE comment (faqID INTEGER, 
   message VARCHAR(256));
Query OK, 0 rows affected (0.45 sec)

mysql> INSERT INTO comment VALUES (1, 'I like it');
Query OK, 1 row affected (0.00 sec)

mysql> CREATE VIEW faqComment AS SELECT f.id, f.title, 
   f.description, c.message FROM faq f, comment c 
   WHERE f.id = c.faqID;
Query OK, 0 rows affected (0.06 sec)

mysql> SELECT * FROM faqComment;
