SqlSugar C#代碼中批量更新時報錯：You cannot have no primary key and no conditions

問題：使用SqlSugar批量更新時報錯“SqlSugar.SqlSugarException: You cannot have no primary key and no conditions”；

  主鍵或條件不存在

  Db.Updateable<User>(users).ExecuteCommand();

解決辦法

  就是用WhereColumns指定條件，無主鍵更新

  Db.Updateable<User>(users).WhereColumns(it => new { it.Id }).ExecuteCommand();
