我有一条语句将其插入数据库中，但是插入后，我想更新中表中的数据webservice。我该怎么做？

这是我插入数据的代码：

 [WebMethod]
    public static void InsertStudentTransaction(string Name, string CLass, string NRIC, int StallNo, float AmountSpent, DateTime GetDate)
     {
        using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString2"].ConnectionString))
     {

        SqlCommand command = new SqlCommand("INSERT Into StudentTransactions (Name, CLass,NRIC,StallNo,AmountSpent, TimeDate) VALUES (@Name, @CLass, @NRIC, @StallNo, @AmountSpent, @GetDate)");

        command.Parameters.AddWithValue("@Name", "Name");
        command.Parameters.AddWithValue("@CLass", "CLass");
        command.Parameters.AddWithValue("@NRIC", "NRIC");
        command.Parameters.AddWithValue("@StallNo","StallNo");
        command.Parameters.AddWithValue("@AmountSpent", "AmountSpent");
        command.Parameters.AddWithValue("@TimeDate", "GetDate");

        command.Connection.Open();
        command.ExecuteNonQuery();
     }

Shamcs

试试这个

[WebMethod]
        public static void UPDATEStudentTransaction(string Name, string CLass, string NRIC, int StallNo, float AmountSpent, DateTime GetDate)
         {
            using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString2"].ConnectionString))
         {

            SqlCommand command = new SqlCommand("UPDATE StudentTransactions set Name=@Name, CLass=@CLass,StallNo=@StallNo,AmountSpent=@AmountSpent, TimeDate=@TimeDate WHERE <condition>");

            command.Parameters.AddWithValue("@Name", Name);
            command.Parameters.AddWithValue("@CLass", CLass);
            command.Parameters.AddWithValue("@NRIC", NRIC);
            command.Parameters.AddWithValue("@StallNo",StallNo);
            command.Parameters.AddWithValue("@AmountSpent", AmountSpent);
            command.Parameters.AddWithValue("@TimeDate", GetDate);

            command.Connection.Open();
            command.ExecuteNonQuery();
         }
