c#Dapper 批量插入Mysql

 <connectionStrings>
    <add name="sqlconnectionString" connectionString="server=127.0.0.1;database=MyDataBase;User=sa;password=123456;Connect Timeout=1000000"/>
    <add name="mysqlconnectionString" connectionString="Database=zyzs_terminal_info;Data Source=192.168.1.220;User Id=root;Password=root;CharSet=utf8;port=3306"/>
  </connectionStrings>

插入时格式与sql 不一样格式

没有方括号[]

 string mysqlconnectionString = ConfigurationManager.ConnectionStrings["mysqlconnectionString"].ToString();
 
        #region 向数据库中添加多条记录 +int Insert(Model.Contacts model)
 
        public int InsertBaseList(List<BaseTable> model)
        {
        #region SQL语句
        const string sql = @"
           INSERT INTO zyzs_terminal_base (license_number,shop_name,user_name,phone_number,shop_address)
            VALUES (

            );select @@IDENTITY";
 
            using (var connection = new MySqlConnection(mysqlconnectionString))
            {
                connection.Open();

MySql.Data.MySqlClient   添加引用

这个方法就是简单insert的方式插入,速度很慢.数据量大,应使用Mysql MySqlBulkLoader 批量上传
