@RecordNoItem INT，

@ItemName NVarChar（200）Out，

@NetStock Money Out

）

As

开始



选择

@ ItemName = tbl_Items.ItemName

来自

tbl_Items

其中

tbl_Items.RecordNoItem =@RecordNoItem < br $>
订购商品

tbl_Items.RecordNoItem



选择

@ NetStock = SUM（ tbl_Stock.ItemIn）-SUM（tbl_Stock.ItemOut）

来自

tbl_Stock

其中

tbl_Stock.RecordNoCompany = @RecordNoItem

现在我正在尝试在sql server management st中执行此过程像这样的udio ......



执行sp_InventoryAnalysis_M 15



但是它给了我以下错误.. 。

Hello to All !

I m working in VB.NET 2010 with SQL Server 2008.

I created a Stored Procedure with output parameter in my Database using SQL Server 2008 Management Studio
Like this ...

Create PROCEDURE sp_InventoryAnalysis_M(

@RecordNoItem INT,
@ItemName NVarChar(200) Out,
@NetStock Money Out
)
As
Begin

Select
@ItemName=tbl_Items.ItemName
From
tbl_Items
Where
tbl_Items.RecordNoItem=@RecordNoItem
Order By
tbl_Items.RecordNoItem

Select
@NetStock=SUM(tbl_Stock.ItemIn)-SUM(tbl_Stock.ItemOut)
From
tbl_Stock
Where
tbl_Stock.RecordNoCompany=@RecordNoItem
End

now i am trying to execute this procedure in sql server management studio like this ...

Execute sp_InventoryAnalysis_M 15

but it gives me the following error ...

Msg 201, Level 16, State 4, Procedure sp_InventoryAnalysis_M, Line 0
Procedure or function 'sp_InventoryAnalysis_M' expects parameter '@ItemName', which was not supplied.

任何人都可以识别我犯错误的地方吗？



第二个问题是我想在我的VB.NET应用程序中执行此过程并从其输出参数中获取值并使用将其分配给变量。



谢谢。

can anyone identify where i made mistake ?

The second question is this i want to execute this procedure in my VB.NET application and get value from its output parameter and use assign it into a variable.

Thanks.
