通过sql case when对商品表自定义属性进行查询，实现行专列效果。

declare @sql varchar(8000)

set @sql='select StyleNo'

select @sql=@sql+','+[A_GoodsAttr].AttrName+'=isnull(max(case AttrName when '''+[A_GoodsAttr].AttrName+''' then AttrValue end),0)'

 from A_GoodsAttr order by AttrId 

set @sql=@sql+' from A_ProAttrList where  1=1 and StyleNo=''100010'' group by StyleNo order by StyleNo'

print @sql

exec(@sql)

1、全部商品自定义属性 2、单货号自定义属性
