AS400 C#.net inserting new record problems

Question

I am trying to build a C#.net program that works like a RPG Subfile on the AS400.

Have the general subfile part working. I can display and then edit and update existing records.

Am blowing up in my code where I am trying to insert a new record. Blowing up on the

cmd.ExecuteNonQuery();

If you want to see how this works without the insert go to

Look at the Website1a

Here is the code.

using IBM.Data.DB2.iSeries;
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class WebForm3 : System.Web.UI.Page
{
     protected void btnBack_Click(object sender, EventArgs e)
    {
        Server.Transfer("WebForm1a.aspx");
    }
    protected void btnUpdate_Click(object sender, EventArgs e)
    {
        ConnectionStringSettingsCollection cssc =
            ConfigurationManager.ConnectionStrings;

        String connString = cssc["FTWAS400"].ToString();

        iDB2Connection conn = new iDB2Connection(connString);

        conn.Open();

        iDB2Command cmd = new iDB2Command(
                   "insert into tburrows.qcustcdt (cusnum, init, lstnam, street, city, state, zipcod, cdtlmt, chgcod, baldue, cdtdue) values (@cusnum, @init, @lstnam, @street, @city, @state, @zipcod, @cdtlmt, @chgcod, @baldue, @cdtdue)", conn);


        cmd.DeriveParameters();

        cmd.Parameters["@cusnum"].Value = Request["txtCUSNUM"];
        cmd.Parameters["@init"  ].Value = Request["txtINIT"];
        cmd.Parameters["@lstnam"].Value = Request["txtLSTNAM"];
        cmd.Parameters["@street"].Value = Request["txtSTREET"];
        cmd.Parameters["@city"].Value   = Request["txtCITY"];
        cmd.Parameters["@state"].Value  = Request["txtSTATE"];
        cmd.Parameters["@zipcod"].Value = Request["txtZIPCOD"];
        cmd.Parameters["@cdtlmt"].Value = Request["txtCDTLMT"];
        cmd.Parameters["@chgcod"].Value = Request["txtCHGCOD"];
        cmd.Parameters["@baldue"].Value = Request["txtBALDUE"];
        cmd.Parameters["@cdtdue"].Value = Request["txtCDTDUE"];


        cmd.ExecuteNonQuery();

        cmd.Dispose();
        conn.Close();

        btnBack_Click(sender, e);
    }
}

Any help will greatly be appreciated.

Answer 1

There is another option within the

cmd.Parameters["@cusnum"].Value = field;

to specify the field type. Use

cmd.Parameters.Add("@cusnum", iDB2DbType.iDB2Decimal).Value = Convert.ToDecimal(field);

instead. This should convert your data types properly. You will need to change the iDB2Decimal to the proper field type if not decimal.
