[sql] SQL multiple column ordering

I am trying to sort by multiple columns in SQL, and in different directions. column1 would be sorted descending, and column2 ascending.

How can I do this?

This question is related to sql sql-order-by

The answer is


SELECT  *
FROM    mytable
ORDER BY
        column1 DESC, column2 ASC

The other answers lack a concrete example, so here it goes:

Given the following People table:

 FirstName |  LastName   |  YearOfBirth
----------------------------------------
  Thomas   | Alva Edison |   1847
  Benjamin | Franklin    |   1706
  Thomas   | More        |   1478
  Thomas   | Jefferson   |   1826

If you execute the query below:

SELECT * FROM People ORDER BY FirstName DESC, YearOfBirth ASC

The result set will look like this:

 FirstName |  LastName   |  YearOfBirth
----------------------------------------
  Thomas   | More        |   1478
  Thomas   | Jefferson   |   1826
  Thomas   | Alva Edison |   1847
  Benjamin | Franklin    |   1706

You can use multiple ordering on multiple condition,

ORDER BY 
     (CASE 
        WHEN @AlphabetBy = 2  THEN [Drug Name]
      END) ASC,
    CASE 
        WHEN @TopBy = 1  THEN [Rx Count]
        WHEN @TopBy = 2  THEN [Cost]
        WHEN @TopBy = 3  THEN [Revenue]
    END DESC 

Multiple column ordering depends on both column's corresponding values: Here is my table example where are two columns named with Alphabets and Numbers and the values in these two columns are asc and desc orders.

Now I perform Order By in these two columns by executing below command:

Now again I insert new values in these two columns, where Alphabet value in ASC order:

and the columns in Example table look like this. Now again perform the same operation:

You can see the values in the first column are in desc order but second column is not in ASC order.
