使用sql server存储过程,可以在数据库中实现多种功能,下面就为您介绍其中的一种,供您参考,希望对您学习sql server存储过程的使用有所帮助。

如果需要同时插入N条数据,不想在程序里控制,但是SQL Sever又不支持数组参数.所以只能用变通的办法了.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sql server存储过程中用SubString配合CharIndex把分割开来。
详细的sql server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
 - Set @PointerCurr=CharIndex(',',@ProductId_Array,@PointerPrev+1)
 - set @TId=cast(SUBSTRING(@ProductId_Array,@PointerPrev,@PointerCurr-@PointerPrev) as int)
 - Insert into ProductListSpecial (ModuleId,ProductId) Values(@ModuleId,@TId)
 - SET @PointerPrev = @PointerCurr
 - while (@PointerPrev+1 < LEN(@ProductId_Array))
 - Begin
 - Set @PointerCurr=CharIndex(',',@ProductId_Array,@PointerPrev+1)
 - if(@PointerCurr>0)
 - Begin
 - set @TId=cast(SUBSTRING(@ProductId_Array,@PointerPrev+1,@PointerCurr-@PointerPrev-1) as int)
 - Insert into ProductListSpecial (ModuleId,ProductId) Values(@ModuleId,@TId)
 - SET @PointerPrev = @PointerCurr
 - End
 - else
 - Break
 - End
 - set @TId=cast(SUBSTRING(@ProductId_Array,@PointerPrev+1,LEN(@ProductId_Array)-@PointerPrev) as int)
 - Insert into ProductListSpecial (ModuleId,ProductId) Values(@ModuleId,@TId)
 - Set NoCount OFF
 - if @@error=0
 - begin
 - commit transaction
 - end
 - else
 - begin
 - rollback transaction
 - end
 - GO
