This tutorial introduces the notion of a join. The database consists of three tables movie , actor and casting .

movie
id	title	yr	director	budget	gross

actor
id	name

casting
*movieid*	*actorid*	ord

1962 movies

what is a cast list?

The cast list is the names of the actors who were in the movie.

Use movieid=11768, (or whatever value you got from the previous question)

SELECT name FROM actor A

LEFT JOIN Casting C ON a.id=c.actorid

LEFT JOIN movie M ON m.id = c.movieid

WHERE movieid=27;

Alien cast list

LEFT JOIN movie M ON m.id = c.movieid

WHERE title ='Alien';

Harrison Ford movies

SELECT title FROM actor A

LEFT JOIN Casting C ON a.id=c.actorid

LEFT JOIN movie M ON m.id = c.movieid

WHERE name = 'Harrison Ford';

Harrison Ford as a supporting actor

List the films where 'Harrison Ford' has appeared - but not in the starring role. [Note: the ord field of casting gives the position of the actor. If ord=1 then this actor is in the starring role]

SELECT title FROM actor A

LEFT JOIN Casting C ON a.id=c.actorid

LEFT JOIN movie M ON m.id = c.movieid

WHERE name = 'Harrison Ford'

And ord <> 1;

Lead actors in 1962 movies

Which were the busiest years for 'Rock Hudson', show the year and the number of movies he made each year for any year in which he made more than 2 movies.

SELECT yr,COUNT(title) FROM movie

JOIN casting ON movie.id=movieid

JOIN actor ON actorid=actor.id

WHERE name='Rock Hudson'

GROUP BY yr

HAVING COUNT(title) > 2；

Lead actor in Julie Andrews movies

12.

List the film title and the leading actor for all of the films 'Julie Andrews' played in.

Did you get "Little Miss Marker twice"?

Julie Andrews starred in the 1980 remake of Little Miss Marker and not the original(1934).

Title is not a unique field, create a table of IDs in your subquery(不知道为什么我没有遇到提示的问题，不过这题的代码是真的长，希望有人能指导一下更加简化的写法呢~）

P.S.橙色部分是重复字段，关联三张表用的

Select title,name FROM actor A

LEFT JOIN Casting C ON a.id=c.actorid

LEFT JOIN movie M ON m.id = c.movieid

Where title IN(SELECT title FROM actor A

LEFT JOIN Casting C ON a.id=c.actorid

LEFT JOIN movie M ON m.id = c.movieid

Where name = 'Julie Andrews')

And ord = 1；

ORDER BY name;

14.

SELECT title,COUNT(DISTINCT actorid) FROM movie M

LEFT JOIN casting C ON m.id = c.movieid

WHERE yr = 1978

GROUP BY title

ORDER BY COUNT(DISTINCT actorid) desc,title;

15.

List all the people who have worked with 'Art Garfunkel'.

P.S.橙色部分是重复字段，关联actor 和 casting表用的。

SELECT DISTINCT name FROM actor A

LEFT JOIN casting C ON a.id=c.actorid

Where name <> 'Art Garfunkel'

And movieid IN(SELECT movieid From actor A

LEFT JOIN casting C ON a.id=c.actorid

WHERE name = 'Art Garfunkel')

ORDER BY name;

JOIN Quiz 2

网址：JOIN Quiz 2 - SQLZOO

1. Select the statement which lists the unfortunate directors of the movies which have caused financial loses (gross < budget)

SELECT name FROM actor

INNER JOIN movie ON actor.id = director

2. Select the correct example of JOINing three tables

SELECT * FROM actor

JOIN casting ON actor.id = actorid

JOIN movie ON movie.id = movieid;

3. Select the statement that shows the list of actors called 'John' by order of number of movies in which they acted

SELECT name, COUNT(movieid) FROM casting

JOIN actor ON actorid=actor.id

WHERE name LIKE 'John %'

GROUP BY name

ORDER BY 2 DESC;

4. Select the result that would be obtained from the following code:

 SELECT title FROM movie JOIN casting ON (movieid=movie.id)JOIN actor   ON (actorid=actor.id)WHERE name='Paul Hogan' AND ord = 1

link the director column in movies with the primary key in actor

connect the primary keys of movie and actor via the casting table

 SELECT title, yr FROM movie, casting, actor WHERE name='Robert De Niro' AND movieid=movie.id AND actorid=actor.id AND ord = 3
