選擇代碼找出以U開頭的國家名稱。

SELECT name
  FROM world
 WHERE name
 BEGIN with U

SELECT name

選擇代碼以顯示英國United Kingdom的人口。

SELECT population
  FROM 'United Kingdom'

SELECT name
  FROM world
 WHERE population = 'United Kingdom'

SELECT FROM world
 WHERE population IN 'United Kingdom'

SELECT population

 WHERE name = 'United Kingdom'

SELECT population
  FROM world
 WHERE 'United Kingdom' IN name

這個SQL代碼有什麼錯處。預計結果應該是含'France'的單列。

continent 應該是 'continent'

'name' 應該是 name

'France' 應該是 "France"

'France' 應該是 France

= 應該是 IN
