Nobel Quiz

nobel
yr subject winner
1960 Chemistry Willard F. Libby
1960 Literature Saint-John Perse
1960 Medicine Sir Frank Macfarlane Burnet
1960 Medicine Peter Medawar
1960 Physics Donald A. Glaser
1960 Peace Albert Lutuli
...

1. Pick the code which shows the name of winner's names beginning with C and ending in n

SELECT name FROM nobel WHERE winner LIKE '%C%' AND winner LIKE '%n%'
SELECT name FROM nobel WHERE winner LIKE '%C' AND winner LIKE 'n%'
SELECT name FROM nobel WHERE winner LIKE 'C%' AND winner LIKE '%n'
SELECT winner FROM nobel WHERE winner LIKE '%C' AND winner LIKE 'n%'
SELECT winner FROM nobel WHERE winner LIKE 'C%' AND winner LIKE '%n'

2. Select the code that shows how many Chemistry awards were given between 1950 and 1960

SELECT COUNT(subject) FROM nobel WHERE subject = 'Chemistry' AND BETWEEN 1950 and 1960
SELECT COUNT(subject) FROM nobel WHERE subject = 'Chemistry' AND yr BETWEEN (1950, 1960)
SELECT COUNT(subject) FROM nobel WHERE subject = 'Chemistry' AND yr BETWEEN 1950 and 1960
SELECT subject FROM nobel WHERE subject = 'Chemistry' AND yr BETWEEN 1950 and 1960
SELECT subject FROM nobel WHERE subject = 'Chemistry' AND yr BETWEEN (1950, 1960)

3. Pick the code that shows the amount of years where no Medicine awards were given

SELECT COUNT(DISTINCT yr) FROM nobel WHERE yr IN (SELECT DISTINCT yr FROM nobel WHERE subject <> 'Medicine')
SELECT COUNT(DISTINCT yr) FROM nobel WHERE yr NOT IN (SELECT DISTINCT yr FROM nobel WHERE subject = 'Medicine')
SELECT DISTINCT yr FROM nobel WHERE yr NOT IN (SELECT DISTINCT yr FROM nobel WHERE subject LIKE 'Medicine')
SELECT COUNT(DISTINCT yr) FROM nobel WHERE yr NOT IN (SELECT DISTINCT yr FROM nobel WHERE subject NOT LIKE 'Medicine')
SELECT COUNT(yr) FROM nobel WHERE yr NOT IN (SELECT DISTINCT yr FROM nobel WHERE subject = 'Medicine')

4. Select the result that would be obtained from the following code: SELECT subject, winner FROM nobel WHERE winner LIKE 'Sir%' AND yr LIKE '196%'

5. Select the code which would show the year when neither a Physics or Chemistry award was given

SELECT yr FROM nobel WHERE subject NOT IN(SELECT yr from nobel WHERE subject IN ('Chemistry','Physics'))
SELECT yr FROM nobel WHERE subject NOT IN(SELECT subject from nobel WHERE subject IN ('Chemistry','Physics'))
SELECT yr FROM nobel WHERE yr NOT IN(SELECT yr from nobel WHERE subject IN ('Chemistry','Physics'))
SELECT yr FROM nobel WHERE yr NOT IN(SELECT subject from nobel WHERE subject IN ('Chemistry','Physics'))
SELECT yr FROM subject WHERE yr NOT IN(SELECT yr from nobel WHERE subject IN ('Chemistry','Physics'))

6. Select the code which shows the years when a Medicine award was given but no Peace or Literature award was

SELECT DISTINCT yr FROM nobel WHERE subject='Medicine' and subject NOT IN(SELECT yr from nobel WHERE subject='Literature') and yr NOT IN (SELECT yr FROM nobel WHERE subject='Peace')
SELECT DISTINCT yr FROM nobel WHERE subject='Medicine' and yr NOT IN(SELECT yr from nobel WHERE subject='Literature' AND subject='Peace')
SELECT DISTINCT yr FROM nobel WHERE subject='Medicine' and yr NOT IN(SELECT yr from nobel WHERE subject='Literature') and yr NOT IN (SELECT yr FROM nobel WHERE subject='Peace')
SELECT DISTINCT yr FROM subject WHERE subject='Medicine' and yr NOT IN(SELECT yr from nobel WHERE subject='Literature' and subject='Peace')
SELECT DISTINCT yr FROM subject WHERE subject='Medicine' and yr NOT IN(SELECT yr from nobel WHERE subject='Literature') and yr NOT IN (SELECT yr FROM nobel WHERE subject='Peace')

7. Pick the result that would be obtained from the following code: SELECT subject, COUNT(subject) FROM nobel WHERE yr ='1960' GROUP BY subject
