1.
自动生化曾的一些查询
可以自定义查询语句
2.自定义查询过程调用
USE [mydb] GO /****** Object: StoredProcedure [dbo].[procLogin] Script Date: 08/14/2017 19:18:31 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author: <Author,,Name> -- Create date: <Create Date,,> -- Description: <Description,,> -- ============================================= ALTER PROCEDURE [dbo].[procLogin] @userName varchar(50), @password varchar(50) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here SELECT * FROM [user] WHERE user_name = @userName AND password = @password END
调用
SqlConneteion conn = new SqlConnection("数据库信息");
SqlCommand command = new SqlCommand("存储过程名"，conn)
command.CommandType = CommandType.StoreProcedure.
command.Parameter是.Add（new SqlParameter("@userName",userName)）;
SqlReader dr = command.executeReader()
一行一行读 读取不到返回false
得到宿处参数值
SqlParameter count = new SqlParameter("@count", 0);
count.Direction = System.Data.ParameterDirection.Output;
command.Parameters.Add(count);
int a= count.value();
