使用sql server存储过程,可以在数据库中实现多种功能,接下来的SQL server内容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。
假如需要同时插入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
