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();
