Transaction usage

Hi,

I would like to implement a daily job in order to read from a database table if there are results, it will insert into two different tables and finally updates the record which is being read from the original table. Is the transaction usage is correct? Can you give me feedback, please?

using log4net;
using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DailyPINReconJob
{
    class Program
    {
       
        private static readonly log4net.ILog log1 = LogManager.GetLogger("FileAppenderError");
        private static readonly log4net.ILog log2 = LogManager.GetLogger("FileAppenderLog");

        static void Main(string[] args)
        {

			SqlTransaction trans; 
			
            try
            {
                DateTime runday = DateTime.Today;
                if (args.Length > 0)
                {
                    Console.WriteLine(args[0].ToString());
                    runday = DateTime.Parse(args[0].ToString());
                }
                using (var conn = new SqlConnection())
                {
                    conn.ConnectionString ="Server=(localdb)\\MSSQLLocalDB; Initial Catalog=Test; Integrated Security=True; MultipleActiveResultSets=True; Trusted_Connection=yes;";
                    conn.Open();
					//Transaction
					trans = connection.BeginTransaction(); 
                    var command = new SqlCommand("SELECT cf.productCode, cf.productDescription, cf.quantity, cf.unitPrice, cf.totalPrice, cf.currency, cf.totalPayablePrice, c.serial, c.pin, c.expiryDate, cf.referenceId, Id FROM [GameConfirmResponses] cf INNER JOIN [Coupons] c ON cf.Id = c.confirmResponseID WHERE cf.purchaseStatusDate>=@Today AND cf.purchaseStatusDate<DATEADD(day,1,@Today) and cf.status in (0,2) and cf.service != 'OUR'", conn, trans);
                    command.Parameters.Add(new SqlParameter("Today", runday));
