ADO.NET 操作 Mysql

 

ADO.NET 操作Mysql

首先要通过Nuget安装mysql.data包， 

 

连接字符串：

 

public static string MysqlCnnectionString = "Server =localhost; Database =test; Uid =root; Pwd =mrf@2017;Pooling=true; Max Pool Size=20;Min Pool Size=10;Allow Batch=true";

　　或者 放在配置文件中：

插入：

static void MysqlInsert()
        {
            var sql = @"INSERT  table_a
                                ( name, create_time, parant_id )
                        VALUES  ( 'test', '2017-01-01', 1 )";
            using (MySqlConnection conn = new MySqlConnection(MysqlCnnectionString))
            {
                conn.Open();
                MySqlHelper.ExecuteNonQuery(conn,sql);
            }
        }

带参数参入

static void MysqlInsertByParameters()
        {
            var sql = @"INSERT  table_a
                                ( name, create_time, parant_id )
                        VALUES  ( @name, @create_time, @parant_id )";
            MySqlParameter[] parameter = new MySqlParameter[3];
            parameter[0] = new MySqlParameter("name", "test");
            parameter[1] = new MySqlParameter("create_time", DateTime.Now);
            parameter[2] = new MySqlParameter("parant_id", 1);
            using (MySqlConnection conn = new MySqlConnection(MysqlCnnectionString))
            {
                conn.Open();
                MySqlHelper.ExecuteNonQuery(conn, sql, parameter);
            }
        }

 

修改：

static void MysqlUpdate()
        {
            var sql = "UPDATE table_a SET name = '1111' where id = 1";
            using (MySqlConnection conn = new MySqlConnection(MysqlCnnectionString))
            {
                conn.Open();
                MySqlHelper.ExecuteNonQuery(conn, sql);
            }
        }

　

删除：

static void MysqlDelete()
        {
            var sql = "delete from  table_a  where id = 1";
            using (MySqlConnection conn = new MySqlConnection(MysqlCnnectionString))
            {
                conn.Open();
                MySqlHelper.ExecuteNonQuery(conn, sql);
            }
        }

　　

查询， 后期补...
