SQL Sever怎样同时插入N条数据而不在程序里控制2012-02-10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 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
