需要將上圖變為下圖結果。
實現行轉列，及把第一張圖片中紅圈的部分的內容放置到 列上，作為列的標題。。。
declare @sql varchar(8000)
select @sql=isnull(@sql+',','')+modelname from #tb group by modelname
set @sql = 'select * from #tb pivot (sum(val) for modelname in ('+@sql+') )a' //val 為值 modelname為需要將行轉列
exec (@sql)
//寫這種sql的思路就是，先自己寫出類似圖一 的結果，確定那一個需要行轉列。。這裡我們就是需要modelname 這一列的值，都放過去作為列的屬性名。。。看圖兩個圈的描述吧。具體本人也不是很好描述。
