Question

Using VB.NET with ASP.NET and and ms-access 2003 data, I’m trying to input data from a web form to the a table in db.mdb called ‘USER’.

I tried this code:

 Protected Sub btnCreateAccount_Click(sender As Object, e As System.EventArgs) Handles btnCreateAccount.Click

    Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\Brian\Documents\Visual Studio 2010\WebSites\WebSite3\db.mdb;User Id=admin;Password=;")

    Dim cmd As OleDbCommand = New OleDbCommand("INSERT INTO USER (Name, Surname, Username, Country, TelNo, Password, Address) VALUES (?, ?, ?, ?, ?, ?, ?)", conn)

    If txtPass.Text = txtCPass.Text Then

        cmd.Parameters.Add("@Name", OleDbType.VarChar, 255).Value = txtName.Text
        cmd.Parameters.Add("@Surame", OleDbType.VarChar, 255).Value = txtSurname.Text
        cmd.Parameters.Add("@Address", OleDbType.VarChar, 255).Value = txtAddress.Text
        cmd.Parameters.Add("@Country", OleDbType.VarChar, 255).Value = txtCountry.Text
        cmd.Parameters.Add("@Username", OleDbType.VarChar, 255).Value = txtUsername.Text
        cmd.Parameters.Add("@Password", OleDbType.VarChar, 255).Value = txtPass.Text
        cmd.Parameters.Add("@TelNo", OleDbType.Integer).Value = txtTelNo.Text

        Try

            conn.Open()
            cmd.ExecuteNonQuery()
            conn.Close()

        Catch ex As OdbcException
            Throw ex
        Finally
            conn.Close()
            lblAccount.Visible = True


        End Try

    End If

End Sub

But it’s returning me an error message:

Any suggestions to why the problem might be cause?

Answer 1

User and Password are reserved keywords. Change the names, or use square brackets around the names in the query:

    Dim cmd As OleDbCommand = New OleDbCommand("INSERT INTO [USER] (Name, Surname, Username, Country, TelNo, [Password], Address) VALUES (?, ?, ?, ?, ?, ?, ?)", conn)

Then, for then next error that you will encounter: As the parameters are not named in the query, the parameter objects in the Parameters collection has to be added in the same order as they are used in the query.
