Missing parameter error after running MySql query

Question

Hello,

I'm completely new to MySql and haven't used SqlDataSource with UpdateParameters before, so I'm probably missing something very obvious.

When trying to update a record, the update does happen but then throws an error saying "'id' parameter is missing at the statement". So the query works and the database gets updated as it should, but an error is thrown afterwards.

These are the update parameters:

<UpdateParameters>
                <asp:Parameter Name="business_name" Type="string" Size="256" />
                <asp:Parameter Name="addr_line_1" Type="string" Size="256" />
                <asp:Parameter Name="addr_line_2" Type="string" Size="256" />
                <asp:Parameter Name="addr_line_3" Type="string" Size="256" />
                <asp:Parameter Name="postcode" Type="string" Size="32" />
                <asp:Parameter Name="county" Type="string" Size="128" />
                <asp:Parameter Name="town_city" Type="string" Size="256" />
                <asp:Parameter Name="tl_url" Type="string" Size="256" />
                <asp:Parameter Name="customer_id" Type="string" Size="16" />
                <asp:Parameter Name="region_id" Type="Int16" />
                <asp:Parameter Name="description" Type="string" Size="1024" />
                <asp:Parameter Name="approval_status" Type="string" Size="1" />
                <asp:Parameter Name="tl_user_name" Type="string" Size="256" />
                <asp:Parameter Name="phone"  Type="string" Size="50" />
                <asp:Parameter Name="uploaders_own" Type="Int16" />
            </UpdateParameters>

Here's the update statement:

UPDATE myTable SET business_name = ?, addr_line_1 = ?, addr_line_2 = ?, addr_line_3 = ?, postcode = ?, county = ?, town_city = ?, tl_url = ?, customer_id = ?, region_id = ?, description = ?, approval_status = ?, tl_user_name = ?, phone = ?, uploaders_own = ? WHERE id = " + id

Here's the stack trace:

Does anyone know what I'm doing wrong?

Answer 1

at the very end of your query id parameter mentioned.
but it doesn't seem to be defined somewhere
