现有两表A，B

A表存储商品点击日志，B表存储商品

要求显示当天所有商品点击量列表并附带总数并按天排序

declare @sql varchar(2000)
set @sql=’select CONVERT(varchar(100), a.[Time], 23) as 时间,count(b.title) as 总数’
select @sql =@sql+ ‘,sum(case b.title when ”’+Title+”’ then 1 else 0 end) as ‘+'[‘+Title+’]’
from (select distinct title from B) as B
set @sql=@sql+’ from A as a left join B as b on a.AId=B.Aid
group by CONVERT(varchar(100), a.[Time], 23) order by CONVERT(varchar(100), a.[Time], 23) desc’
exec(@sql)

显示结果

时间	总数	商品1	商品2	商品3
