使用存储过程更新数据库！成功了但是返回值为 -1 的变态问题的解决办法！

今天遇到个表态的问题！使用带事务的存储过程执行sql语句，看数据库里面插入更新都正常！ 但是返回值一直为-1！ 头那个大哦！ 先贴2个存储过程吧！看大侠们能否找到问题的存在 USE [RevolutionDB_Test] GO /****** Object: StoredProcedure [dbo].[UpdatePointByUser] Script Date: 03/29/2010 16:06:23 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author:jinho -- Create date: 2010年3月22日16:13:06 -- Description: 修改用户的点数 [Point] -- ============================================= ALTER PROCEDURE [dbo].[UpdatePointByUser] @point int = 0, @uid int =0 AS BEGIN SET NOCOUNT ON; declare @error int ; set @error = 0; -- Insert statements for procedure here begin tran update UserInfo set Point = Point + @point where Id = @uid; set @error = @error+@@error; if(@error=0) commit tran ; else rollback tran; END ////////////////////////////////////////////////////////////// USE [RevolutionDB_Test] GO /****** Object: StoredProcedure [dbo].[AddAnnouncement] Script Date: 03/29/2010 15:43:51 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[AddAnnouncement] @ATitle nvarchar(max) ='', @ACreateTime datetime ='', @AWhere nvarchar(max) = '', @AUserId int =0, @point int =0 AS BEGIN SET NOCOUNT ON; declare @error int ; set @error = 0; begin tran insert into Announcements values(@ATitle,@ACreateTime,@AWhere,@AUserId); set @error = @error+@@error; exec UpdatePointByUser @point,@AUserId set @error = @error+@@error; if(@error=0) commit tran ; else rollback tran; END declare @rev int exec [AddAnnouncement] 'mytest','2008-05-09','ChengDu',13,-1222200 print @rev; print @@ROWCOUNT 这里测试 @rev,@@ROWCOUNT 都为0; C# 代码: public bool AddAnnouncement(Model announcement) { SqlConnection con = null; SqlCommand cmd = null; int row = 0; SqlParameter[] paras = {new SqlParameter("@ATitle",announcement.ATitle), new SqlParameter("@ACreateTime",announcement.ACreateTime), new SqlParameter("@AWhere",announcement.AWhere), new SqlParameter("@AUserId",announcement.AUserId), new SqlParameter("@point",1)}; try { using (con = new SqlConnection(DBHelper.DefaultConnectionString)) { con.Open(); using (cmd = new SqlCommand("[AddAnnouncement]", con)) { cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddRange(paras); row = cmd.ExecuteNonQuery(); return row > 0; } } } catch (Exception) { throw; } finally { if (con != null) con.Close(); } 上面代码的Row返回为-1！ 但是我去数据库看,执行存储过程的两条语句都成功了！ 嘿嘿：注意看到上面的存储过程的“SET NOCOUNT ON;”这句代码！就是他在作怪！他的意思为 “开启设置不影响的行数”！ 你只要 把SET NOCOUNT OFF即可！ 当然也可以不写!因为默认为OFF!如果你看到默认为ON时请修改为OFF！ OK！
