FreeSql （五）插入数据

var connstr = "Data Source=127.0.0.1;Port=3306;User ID=root;Password=root;" + 
    "Initial Catalog=cccddd;Charset=utf8;SslMode=none;Max pool size=10";

IFreeSql fsql = new FreeSql.FreeSqlBuilder()
    .UseConnectionString(FreeSql.DataType.MySql, connstr)
    .UseAutoSyncStructure(true) //自动同步实体结构到数据库
    .Build();

[Table(Name = "tb_topic")]
class Topic {
    [Column(IsIdentity = true, IsPrimary = true)]
    public int Id { get; set; }
    public int Clicks { get; set; }
    public string Title { get; set; }
    public DateTime CreateTime { get; set; }
}

插入

fsql.Insert(new Topic { Id = a + 1, Title = $"newtitle0", Clicks = 100 }).ExecuteAffrows();

执行SQL如下：

INSERT INTO `tb_topic`(`Clicks`, `Title`, `CreateTime`) VALUES(?Clicks0, ?Title0, ?CreateTime0)
