Question

I have a select query that currently produces the following results:

Description   Code    Price  Product 1     A        5  Product 1     B        4  Product 1     C        2 

Using the following query:

SELECT DISTINCT np.Description, p.promotionalCode, p.Price FROM            Price AS p INNER JOIN                          nProduct AS np ON p.nProduct = np.Id 

I want to produce the following:

Description  A  B  C  Product 1   5  4  2 

Answer 1

SELECT      np.Id,      np.Description,      MIN(Case promotionalCode WHEN 'A' THEN Price ELSE NULL END) AS 'A',     MIN(Case promotionalCode WHEN 'B' THEN Price ELSE NULL END) AS 'B',     MIN(Case promotionalCode WHEN 'C' THEN Price ELSE NULL END) AS 'C' FROM      Price AS p  INNER JOIN nProduct AS np ON p.nProduct = np.Id GROUP BY      np.Id,     np.Description

Here is a simple test example:

DECLARE @temp TABLE (     id INT,     description varchar(50),     promotionalCode char(1),     Price smallmoney )  INSERT INTO @temp select 1, 'Product 1', 'A', 5     union SELECT 1, 'Product 1',  'B', 4     union SELECT 1, 'Product 1', 'C', 2    SELECT     id,     description,     MIN(Case promotionalCode WHEN 'A' THEN Price ELSE NULL END) AS 'A',     MIN(Case promotionalCode WHEN 'B' THEN Price ELSE NULL END) AS 'B',     MIN(Case promotionalCode WHEN 'C' THEN Price ELSE NULL END) AS 'C' FROM      @temp GROUP BY      id,     description
