Question

我试图在OpenCart中从MySQL插入小时和分钟相反，当我点击单独保存

时，将更新输入值更新为12:00 AM

这是查询

$this->db->query("UPDATE " . DB_PREFIX . "delivery_time SET delivery_time_name = '" . $this->db->escape($data['delivery_time_name']) . "', delivery_time_from = 'TIME( STR_TO_DATE( " . $this->db->escape($data['delivery_time_from']) . ", \"%h:%i %p\" ) )', delivery_time_to = '" . $this->db->escape($data['delivery_time_to']) . "', status = '" . (int)$data['status'] . "' WHERE delivery_time_id = '" . (int)$delivery_time_id . "'");

但同样适用于phpmyadmin

UPDATE `oc_delivery_time` SET `delivery_time_name`="Slot2",`delivery_time_from`=TIME( STR_TO_DATE( "9:30 AM", "%h:%i %p" ) ),`delivery_time_to`=TIME( STR_TO_DATE( "12:00 PM", "%h:%i %p" ) ),`status`="1" WHERE `delivery_time_id`="2"

Answer 1

您应该使用%H代替%h，错误的模式

h 代表00到12

H 表示00至23

Answer 2

使用MySQL interval或STR_TO_DATE('1:00 PM', ' %h:%i')+ interval 12 hour

Select STR_TO_DATE('1:00 PM', ' %h:%i')+ interval 12 hour

或尝试此查询： -

using System.Globalization;
using Microsoft.Win32;

namespace MyFirstAddIn
{
// Early binding. Doesn't need AutoDual.

public interface IFinancialFunctions
{
    double Bid(string symbol);
    double Ask(string symbol);
    double[,] BidnAsk(string symbol, string direction = null);
}

{
    // Private class members.
    private static readonly WebClient webClient = new WebClient();
    private const string UrlTemplate = "http://finance.yahoo.com/d/quotes.csv?s={0}&f={1}";

    // Private method - data download.
    private static double GetDoubleDataFromYahoo(string symbol, string field)
    {
        string request = string.Format(UrlTemplate, symbol, field);
        string rawData = webClient.DownloadString(request);

        return double.Parse(rawData.Trim(), CultureInfo.InvariantCulture);
    }

    // Public "interface" methods.
    public double Bid(string symbol)
    {
        return GetDoubleDataFromYahoo(symbol, "b3");
    }

    public double Ask(string symbol)
    {
        return GetDoubleDataFromYahoo(symbol, "b2");
    }

    public double[,] BidnAsk(string symbol, string direction = null)
    {
        double bid = GetDoubleDataFromYahoo(symbol, "b3");
        double ask = GetDoubleDataFromYahoo(symbol, "b2");

        return direction == "v" ? new[,]{{bid}, {ask}} : new[,]{{bid, ask}};
    }

    [ComRegisterFunctionAttribute]
    public static void RegisterFunction(Type type)
    {
        Registry.ClassesRoot.CreateSubKey(GetSubKeyName(type, "Programmable"));
        RegistryKey key = Registry.ClassesRoot.OpenSubKey(GetSubKeyName(type, "InprocServer32"), true);
        key.SetValue("",System.Environment.SystemDirectory + @"\mscoree.dll",RegistryValueKind.String);
    }

    [ComUnregisterFunctionAttribute]
    public static void UnregisterFunction(Type type)
    {
        Registry.ClassesRoot.DeleteSubKey(GetSubKeyName(type, "Programmable"), false);
    }

    private static string GetSubKeyName(Type type, string subKeyName)
    {
        System.Text.StringBuilder s = new System.Text.StringBuilder();
        s.Append(@"CLSID\{");
        s.Append(type.GUID.ToString().ToUpper());
        s.Append(@"}\");
        s.Append(subKeyName);

        return s.ToString();
    }  
}
}
