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)
Using the SELECT
statement.
Winners from 1950
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
1962 Literature
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'
Albert Einstein
Show the year and subject that won 'Albert Einstein' his prize.
SELECT yr, subject
FROM nobel
WHERE winner = 'Albert Einstein'
Recent Peace Prizes
Give the name of the 'Peace' winners since the year 2000, including 2000.
SELECT winner
FROM nobel
WHERE subject = 'Peace'
AND yr >= 2000
Literature in the 1980's

'Literature')
SELECT * FROM nobel
WHERE winner IN ('Theodore Roosevelt',
'Woodrow Wilson',
'Jimmy Carter',
'Barack Obama')

Show the winners with first name John
SELECT winner FROM nobel
WHERE winner LIKE 'John %'
Chemistry and Physics from different years
Show the year, subject, and name of Physics winners for 1980 together with the Chemistry winners for 1984.
SELECT *
FROM nobel
WHERE (subject='physics' AND yr=1980) OR
(subject='chemistry' AND yr=1984)
Exclude Chemists and Medics
Show the year, subject, and name of winners for 1980 excluding Chemistry and Medicine
SELECT *
FROM nobel
WHERE yr=1980 AND
subject NOT IN ('Chemistry','Medicine')
Early Medicine, Late Literature
Show year, subject, and name of people who won a 'Medicine' prize in an early year (before 1910, not including 1910) together with winners of a 'Literature' prize in a later year (after 2004, including 2004)

List the winners, year and subject where the winner starts with Sir. Show the the most recent first, then by name order.
SELECT winner, yr, subject
FROM nobel
WHERE winner LIKE 'Sir%'
ORDER BY yr DESC, winner
Chemistry and Physics last
The expression subject IN ('Chemistry','Physics') can be used as a value - it will be 0 or 1.
Show the 1984 winners and subject ordered by subject and winner name; but list Chemistry and Physics last.
SELECT winner, subject, subject IN ('Physics','Chemistry')
FROM nobel
WHERE yr=1984
ORDER BY subject,winner
select winner, subject
from nobel
where yr=1984
order by subject in ('Physics','Chemistry'),subject,winner
