Question

I have the following code:

updated

 try
    {
        ArticleId = Request.QueryString["ArticleId"].ToString();
        NewArticleTitle = Request.Form["ArticleTitle"].ToString();
        NewArticleDate = Request.Form["ArticleDate"].ToString();
        NewArticleBody = Request.Form["ArticleBody"].ToString();


        string dpath = Server.MapPath(@"App_Data") + "/MySite.mdb";
        string connectionstring = @"Data source='" + dpath + "';Provider='Microsoft.Jet.OLEDB.4.0';";
        OleDbConnection con = new OleDbConnection(connectionstring);
        string QuaryString = String.Format("update tblarticles set articletitle='{0}', articlebody='{1}', postdate='{2}'  where articleid={3}", NewArticleTitle, NewArticleBody, NewArticleDate, ArticleId);
        OleDbCommand cmd = new OleDbCommand(QuaryString, con);
        OleDbDataAdapter da = new OleDbDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds, "tbl");
        con.Close();
        Response.Redirect("ArticlesTable.aspx");
    }
        catch { }

The ArticleId is an AUTO INCREMENT (in number type)
When it got to this line da.Fill(ds, "tbl"); the program coutinue to the catch.
My quastion is how can I prevent it so the table will be really update ?
Wish for help, thanks!

Answer 1

As the ArticleId is Numeric so you need to replace this:

where ArticleId='{3}'

With this:

where ArticleId={3}

So your where clause should look like:

"update tblArticles set ArticleTitle='{0}', ArticleBody='{1}',PostDate='{2}'  where ArticleId={3}"
