C# 中的数据库操作~存储过程篇Mysql SqlServer

• Mysql
  • 存储过程查询方式
• SQL server
  • 普通数据库操作
  • EF 调用SQL SERVER存储过程

Mysql

存储过程查询方式：

  public  NetPort GetNetdevicePortName(string uuid)
        {
var ret = new NetPort();
try
            {

                MySqlDataReader myreader = null;
                MySqlCommand myCommand = null;


using (MySqlConnection connection = new MySqlConnection(_connectionMysqlString))
                {

                    connection.Open();
                    myCommand = new MySqlCommand();
                    myCommand.Connection = connection;
                    myCommand.CommandText = "Pro_GetNetdevice_Typename";
                    myCommand.CommandType = CommandType.StoredProcedure;
                    MySqlParameter uuidParameter = new MySqlParameter("?uuid", MySqlDbType.String);//mysql的存储过程参数是以?打头的！！！！
                    uuidParameter.Value = uuid;
                    myCommand.Parameters.Add(uuidParameter);
                    myreader=myCommand.ExecuteReader();
                    List<string> PortNames = new List<string>();
                    List<string> FeatureIds = new List<string>();
while (myreader.Read())
                    {
                        PortNames.Add(myreader["type_name"].ToString());
                        FeatureIds.Add(myreader["featureid"].ToString());
                    }
                    ret.PortNames = PortNames;
                    ret.FeatureIds = FeatureIds;
return ret;
                }

            }
catch (Exception ex)
            {
                _log.Error("查询端口失败" + ex);
return null;
            }
        }  

SQL server

普通数据库操作

    var ret = new List<ChartConfig>();
            try
            {

                using (SqlConnection conn=DbHelper.GetConnection())
                {
                    conn.Open();
                string sql = "SELECT * FROM Netdevice_DetailView_Config where Category=@category";
                    SqlCommand command = conn.CreateCommand();
                    command.CommandType = CommandType.Text;
                    command.CommandText = sql;
                    command.Parameters.Add("@Category",SqlDbType.VarChar);
                    command.Parameters["@Category"].Value = category; 
                    SqlDataReader reader = command.ExecuteReader();
                    while (reader.Read())
                    {                      
                          var Node = new ChartConfig
                        {
                            Category = reader["Category"].ToString(),
                            FeatureIds = Array.ConvertAll(reader["FeatureId"].ToString().Split(','), new Converter<string, int>(int.Parse)),
                            FeatureNames = reader["FeatureName"].ToString().Split(','),
                            Title = reader["TitleFormat"].ToString()
                        };
ret.Add(Node); 
                    }
                    return ret;
                }

            }
            catch (Exception ex)
            {
                _log.Error("查询网络设备配置数据失败" + ex);
                return null;
            }  

EF 调用SQL SERVER存储过程

  using (var ctx = new busContext())
            {
                SqlParameter[] para = new SqlParameter[] {
new SqlParameter("@in_station_id",1),
new SqlParameter("@in_register_type",2)
                };
var busDetails = ctx.Database.SqlQuery<BusDetail>("EXEC [dbo].[bus_message] @in_station_id,@in_register_type", para);
                Console.WriteLine(busDetails.First().sname);
                Console.ReadLine();
            }

待更新，mysql普通操作，sqlserver调用存储过程
