c# - 按降序排列日期

Question

我想在 Gridview 中默认以降序显示日期。

DataTable dt = new DataTable();
SqlDataAdapter adp = 
   new SqlDataAdapter("SELECT Customer.CustomerID, Customer.lastname, Customer.firstname, 
                              Ticket.Date, Ticket.Store, Ticket.Amount, Ticket.NoStub " +
                      "FROM Customer INNER JOIN Ticket ON Customer.CustomerID = Ticket.CustomerID 
                       WHERE Customer.CustomerID like " + txtCustomerID.Text, cn);
adp.Fill(dt);
gvHistory.DataSource = dt;

Answer 1

只需添加:

 order by Ticket.Date desc

到你的sql语句的结尾，像下面这样:

DataTable dt = new DataTable();
        SqlDataAdapter adp = new SqlDataAdapter("SELECT Customer.CustomerID,             Customer.lastname, Customer.firstname, Ticket.Date, Ticket.Store, Ticket.Amount, Ticket.NoStub " +
                                                "FROM Customer INNER JOIN Ticket ON Customer.CustomerID = Ticket.CustomerID WHERE Customer.CustomerID like " + txtCustomerID.Text + " order by Ticket.Date desc", cn);
        adp.Fill(dt);
        gvHistory.DataSource = dt;
