报错：
在将 varchar 值 'select ProductID from dbo.Product where PdTypeID in (select PdTypeID from dbo.ProductType where PdTypeParentID in (select PdTypeID from dbo.ProductType where PdTypeParentID=1))' 转换成数据类型 int 时失败。
visual代码： string storeName = "pd_SearchHotTypeProduct";
SqlParameter[] paramters = { new SqlParameter("@Condition",SqlDbType.VarChar,200) };
paramters[0].Value = condtion;
DataSet ds = DbHelperSQL.RunProcedureDs(storeName, paramters);
return ds;
sql 存储过程：create procedure pd_SearchHotTypeProduct
(
@Condition varchar(250)--类型条件--
)
as
create table #ProductSell(ProductID int,totalSum int)--产品销售表--
insert into #ProductSell select ProductID,sum([Sum]) as totalSum from dbo.OrderList where ProductID in (@Condition) group by ProductID order by totalSum desc
select top 15 ProductID,Name from dbo.Product where ProductID in
(select ProductID from #ProductSell )
drop table #ProductSell
go

怎么置顶？
@星休: insert into #ProductSell select ProductID,sum([Sum]) as totalSum from dbo.OrderList where ProductID in (@Condition) group by ProductID order by totalSum desc 这种代码是走不通的。不能直接在in里面跟动态sql。一般做法是你顶一个临时表，然后利用exec将@Condition的查询结果写入到临时表中，然后在in里面用，select * from #TempTable
@幻天芒: create procedure pd_SearchHotTypeProduct
(
@Condition varchar(250)--类型条件--
)
as
create table #ProductSell(ProductID int,totalSum int)--产品销售表--
create table #ConditionTable(ProductID int)
insert into #ConditionTable select ProductID from (@Condition) as condition --消息 102，级别 15，状态 1，过程 pd_SearchHotTypeProduct，第 8 行
')' 附近有语法错误。--
insert into #ProductSell select ProductID,sum([Sum]) as totalSum from dbo.OrderList where ProductID in (select ProductID from #ConditionTable) group by ProductID order by totalSum desc
select top 15 ProductID,Name from dbo.Product where ProductID in
(select ProductID from #ProductSell )
drop table #ProductSell
go
@幻天芒: 帮看一下急
@星休: from之后不支持参数~
