How to Update All Rows of Table SQL

Question

Below is my code:

@{

    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>

This is the result:

So what I want to do is update my whole table.

What is the SQL query to do this? I want to update Points and Games Played in my database for all teams once the form is posted.

   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);

   }
