我正在尝试在 SQL 数据库类型中将邮政编码设为 VarChar，并将其与字母和数字一起提交到数据库中。当邮政编码具有 int SQL 数据库类型时，表单将提交到数据库中的 zip 列，但当邮政编码的值为 VarChar 50 时，该值不会提交到名为 zipPostal 的数据库中的新列。
这是aspx中的代码：
<asp:Label runat="server" ID="zipLabel" AssociatedControlID="zip">Zip/Postal
Code</asp:Label>
<asp:TextBox ID="zip" name="zip" runat="server"></asp:TextBox>
以下是 C# 中的代码片段：
/// Form post data from registration form
string username = Request.Form["UserName"];
string first = Request.Form["first"];
string last = Request.Form["last"];
string zip = Request.Form["zip"];
sqlCommand.Parameters.Add(new SqlParameter("@email", SqlDbType.VarChar, 50,
ParameterDirection.Input, false, 0, 0, "", DataRowVersion.Proposed, emails));
sqlCommand.Parameters.Add(new SqlParameter("@username", SqlDbType.VarChar, 15,
ParameterDirection.Input, false, 0, 0, "", DataRowVersion.Proposed, username));
sqlCommand.Parameters.Add(new SqlParameter("@firstName", SqlDbType.VarChar, 20,
ParameterDirection.Input, false, 0, 0, "", DataRowVersion.Proposed, first));
sqlCommand.Parameters.Add(new SqlParameter("@lastName", SqlDbType.VarChar, 20,
ParameterDirection.Input, false, 0, 0, "", DataRowVersion.Proposed, last));
sqlCommand.Parameters.Add(new SqlParameter("@zip", SqlDbType.VarChar, 50,
ParameterDirection.Input, false, 0, 0, "", DataRowVersion.Proposed, zip));
SQL 命令类型：
int chk = sqlCommand.ExecuteNonQuery();
public string CheckEmail(string Email)
{
string returnValue = string.Empty;
SqlConnection conn = new SqlConnection(strConnection);
SqlCommand sqlCommand = new SqlCommand
("CheckEmailAvailability", conn);
try
{
sqlCommand.CommandType =
CommandType.StoredProcedure;
sqlCommand.Parameters.AddWithValue("@Email",
Email.Trim());
conn.Open();
returnValue = sqlCommand.ExecuteScalar().ToString();
conn.Close();
}
catch
{
}
finally
{
conn.Close();
sqlCommand.Dispose();
}
return returnValue;
}
////
public string CheckUsername(string Username)
{
string returnValue = string.Empty;
SqlConnection conn = new SqlConnection(strConnection);
SqlCommand sqlCommand = new SqlCommand
("CheckUsernameAvailability", conn);
try
{
sqlCommand.CommandType =
CommandType.StoredProcedure;
sqlCommand.Parameters.AddWithValue("@UserName",
Username.Trim());
conn.Open();
returnValue = sqlCommand.ExecuteScalar().ToString();
conn.Close();
}
catch
{
}
finally
{
conn.Close();
sqlCommand.Dispose();
}
return returnValue;
}
}
//存储过程
if (username != "")
{
string checkUN = CheckUsername(username);
if (checkUN == "true")
{
Label2.Text = "Username already exists.";
gotoauth = 0;
return;
}
}
//[ckc] end check username
if (password != confirmpwd)
{
Label2.Text = "The Password and Confirmation
Password must match.";
gotoauth = 0;
return;
}
//connection with db and call procedure.
SqlConnection conn = new SqlConnection(strConnection);
SqlCommand sqlCommand = new SqlCommand
("customers_insert", conn);
sqlCommand.CommandType = CommandType.StoredProcedure;
conn.Open();
try
{
if (gotoauth == 0)
{}
else
{
var customerGateway = new
CustomerGateway(_loginApikey, _TransactionKey,
ServiceMode.Live);
var NewCustomer = customerGateway.CreateCustomer
(emails, "Live User Account");
var datetime = DateTime.Now.ToString();
string proid = NewCustomer.ProfileID;
Session["Customerproid"] = proid;

在 SQL 数据库中，有一列用于 zip（int，not null）和一列用于 zipPostal（varChar(50)，null）。我希望邮政编码数据进入 zipPostal 列，以便它接受字母和数字。
任何帮助将不胜感激。
