DECLARE @cols As nvarchar(max), @query As nvarchar(MAX);

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(agent_first_name) FROM #Temp2
               FOR XML PATH(''), TYPE

              ).value('.', 'nvarchar(max)')
               ,1,1,'');



Set @query ='Select question_text, ' + @cols +'

From
(

	Select question_text,  agent_first_name,avgcount
	From #Temp2
) As SourceTable Pivot
(
	avg(avgcount) For agent_first_name In (' + @cols + ')
) As PivotTable'
print @query
EXECUTE sp_executesql @query
