Nobel Laureates
We continue practicing simple SQL queries on a single table.
This tutorial is concerned with a table of Nobel prize winners:
nobel(yr, subject, winner)
Exercises
Using the SELECT
statement.
Change the query shown so that it displays Nobel prizes for 1950.
SELECT yr, subject, winner
FROM nobel
WHERE yr = 1960
SELECT yr, subject, winner
FROM nobel
WHERE yr = 1950
Show who won the 1962 prize for Literature.
SELECT winner
FROM nobel
WHERE yr = 1960
AND subject = 'Physics'
SELECT winner
FROM nobel
WHERE yr = 1962
AND subject = 'Literature'
Show the year and subject that won 'Albert Einstein' his prize.
SELECT yr, subject
FROM nobel
WHERE winner = 'Albert Einstein'
Give the name of the 'Peace' winners since the year 2000, including 2000.
SELECT winner
FROM nobel
WHERE subject = 'Peace'
AND yr >= 2000
Show all details (yr, subject, winner) of the Literature prize winners for 1980 to 1989 inclusive.
SELECT yr,subject,winner
FROM nobel

AND yr BETWEEN 1980 AND 1989
Show all details of the presidential winners: ('Theodore Roosevelt', 'Woodrow Wilson', 'Jed Bartlet', 'Jimmy Carter')
SELECT * FROM nobel

AND subject IN ('Cookery',

'Literature')
SELECT * FROM nobel
WHERE winner IN ('Theodore Roosevelt',
'Woodrow Wilson',
'Jed Bartlet',
'Jimmy Carter')
Show the winners with first name John
SELECT winner FROM nobel
WHERE winner LIKE 'John %'
In which years was the Physics prize awarded but no Chemistry prize. (WARNING - this question is way too hard for this level, you will need to use sub queries or joins).
SELECT DISTINCT yr
FROM nobel
WHERE subject='Physics' and yr NOT IN
(SELECT yr from nobel
WHERE subject='Chemistry')
