You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Write a query to divide countries into these groups:

Continent id Belongs to Actual continent (for interest)
1 or 3 Eurasia Europe or Asia
5 or 6 Americas North and South America
2 or 4 Somewhere hot Africa and Australasia
7 Somewhere cold Antarctica
Otherwise Somewhere else International

Your query (based only on the tblCountry table) should show the following results:

Countries in order

The first few countries, sorted in reverse alphabetical order by your new column.

 

Save this query as Continental Drift, then close it down.

-- This should work---

 

SELECT [CountryName]
      ,CASE
      WHEN [ContinentID] in ('1','3') then 'Eurasia'
      When [ContinentID] in ('5','6') then 'Americas'
      When [ContinentID] in ('2','4') then 'Somewhere hot'
      When [ContinentID] = 7 then 'Somewhere cold'
      ELSE 'Somewhere else' END as 'CountryLocation'
  FROM [WorldEvents].[dbo].[tblCountry]
  order by CountryLocation desc
