SQL Server Pivot or "dynamic" query data available for join

I have the following code that creates the data I want
CREATE TABLE #CourseSales
(Course VARCHAR(50),Year INT,Earning MONEY)
GO
--Populate Sample records
INSERT INTO #CourseSales VALUES('.NET',2012,10000)
INSERT INTO #CourseSales VALUES('Java',2012,20000)
INSERT INTO #CourseSales VALUES('.NET',2012,5000)
INSERT INTO #CourseSales VALUES('.NET',2013,48000)
INSERT INTO #CourseSales VALUES('Java',2013,30000)
GO



DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)
 
--Get distinct values of the PIVOT Column
SELECT @ColumnName= ISNULL(@ColumnName + ',','')
       + QUOTENAME(Course)
FROM (SELECT DISTINCT Course FROM #CourseSales) AS Courses
 
--Prepare the PIVOT query using the dynamic
SET @DynamicPivotQuery =
  N'SELECT Year, ' + @ColumnName + '
    FROM #CourseSales
    PIVOT(SUM(Earning)
          FOR Course IN (' + @ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql @DynamicPivotQuery

What I need is for the result to be available to join on an actual table Individuals

So I can select like this...

Select i.FirstName, i.LastName, i.BirthDate, r.*
From Individuals i
JOIN @resultdata r on i.IndividualID, r.IndividualID
