怎样同时插入N条数据而不在程序里控制

怎样同时插入N条数据而不在程序里控制

问:“怎样同时插入N条数据,却不在程序里控制?”

答:“由于SQL Sever不支持数组参数.所以只能用另类的办法了.利用SQL Server强大的字符串处理传把数组格式化为类似"1,2,3,4,5,6"。

然后在存储过程中用SubString配合CharIndex把分割开来。

详细的存储过程:

CREATE PROCEDURE dbo.ProductListUpdateSpecialList

@ProductId_Array varChar(800),

@ModuleId int

AS

DECLARE @PointerPrev int

DECLARE @PointerCurr int

DECLARE @TId int

Set @PointerPrev=1

set @PointerCurr=1

begin transaction

Set NoCount ON

delete from ProductListSpecial where ModuleId=@ModuleId

-- If empty, return

IF (@ProductId_Array IS NULL OR LEN(LTRIM

(RTRIM(@ProductId_Array))) = 0)

RETURN

DECLARE @idoc int

EXEC sp_xml_preparedocument @idoc OUTPUT, @ProductId_Array

Insert into ProductListSpecial (ModuleId,ProductId)

Select

@ModuleId,C.[ProductId]

FROM

OPENXML(@idoc, '/Products/Product', 3)

with (ProductId int ) as C

where

C.[ProductId] is not null

EXEC sp_xml_removedocument @idoc
