如何更新表SQL的所有行

Question

以下是我的代码：

@{

    Layout = "/_SiteLayout.cshtml";
    var db = Database.Open("MyDatabase");

    var query = "SELECT * FROM Team";
    var Teams = db.Query(query);
 }

    <form>
        <table>
        <tr>
            <td>Team Name</td>
            <td>Played</td>
            <td>Points</td>
        </tr>
  @{  foreach(var Team in Teams){
        <tr>
            <td>@Team.TeamName</td>
            <td><input type="text" value="@Team.Played" name="Played"/></td>
            <td><input type="text" value="@Team.Points" name="Points"/></td>
        </tr>
    }    
   }        
        </table>
    </form>

结果如下：

所以我想做的就是更新我的整个表格。

执行此操作的SQL查询是什么？我希望在发布表单后，为我的数据库中的所有团队更新Points和Games Played。

我实际上并不明白你想要实现的目标（用什么来更新你的整个表格？），但这里有一些你可能会觉得有用的信息：

以下是我的解决方案。任何人都有一个有效的解决方案？

@ {

var db = Database.Open("MYDATABSE");

var query = "SELECT * FROM Team";
var Teams = db.Query(query);
var InsertQuery = "";
if(IsPost){

   foreach(var Team in Teams){
       var Points = Request[Team.TeamName];
       var TeamId = Team.TeamId.ToString();
       var Played = Request[TeamId];

       var executeQueryString="UPDATE Team Set Points=@0, Played=@1 WHERE TeamId=@2";
       db.Execute(executeQueryString, Points, Played, Team.TeamId);

   }
   Response.Redirect("~/UpdateTable.cshtml");

}

}

 <form  action="" method="post">
        <table>
        <tr>
            <td><h5>Team Name</h5></td>
            <td><h5>Played</h5></td>
            <td><h5>Points</h5></td>
        </tr>
  @{  foreach(var Team in Teams){
        <tr>
            <td>@Team.TeamName</td>
            <td><input type="text" value="@Team.Played" name="@Team.TeamId"/></td>
            <td><input type="text" value="@Team.Points" name="@Team.TeamName"/></td>
        </tr>
    }    
   }
