sql动态行转列的两种方法

　　本文标签：sql,动态行,转列

第一种方法：

复制代码 代码如下:

select *from ( select Url,case  when  Month=01 then  1月 when  Month=02 then 2月 when  Month=03 then  3月 when  Month=04 then 4月 when  Month=05 then  5月 when  Month=06 then 6月 when  Month=07 then  7月 when  Month=08 then 8月 when  Month=09 then  9月 when  Month=10 then 10月 when  Month=11 then  11月 when  Month=12 then 12月

 end  month,Quality from  (

select Url,DATENAME(M,AuditingTime)Month,SUM(Quality) Quality from  tb_order as a left join  tb_WebSiteInfo as b on a.WebSiteInfoID=b.ID left join  tb_OrderList as c on c.OrderID=a.ID where AuditingTime>2013-01-01 and b.ID>0 and Auditing=2

group by Url,DATENAME(M,AuditingTime) )as h ) as hh

 pivot ( sum(Quality) for month in([1月],[2月],[3月],[4月],[5月],[6月],[7月],[8月],[9月],[10月],[11月],[12月])) as a


第二种方法：
复制代码 代码如下:

declare @sql varchar(8000)

select @sql = isnull(@sql + , , ) + [+CONVERT(varchar(7),AuditingTime,20)+]

from  tb_order as a left join  tb_WebSiteInfo as b on a.WebSiteInfoID=b.ID left join  tb_OrderList as c on c.OrderID=a.ID where AuditingTime>2013-01-01 and b.ID>0 and Auditing=2

group by CONVERT(varchar(7),AuditingTime,20) print @sql declare @sql2 varchar(8000)= set @sql2= select *from (

select Url, CONVERT(varchar(7),AuditingTime,20) AuditingTime,SUM(Quality) Quality from  tb_order as a left join  tb_WebSiteInfo as b on a.WebSiteInfoID=b.ID left join  tb_OrderList as c on c.OrderID=a.ID where b.ID>0 and Auditing=2

group by Url, CONVERT(varchar(7),AuditingTime,20)

) as hh pivot (sum(Quality) for AuditingTime in ( + @sql + )) b

print @sql2

exec(@sql2)
