I have a dropdown box with 3 selections in it. I placed some code to dynamically show from the database the current field it is set to however it is duplicated with my static choices. is there a way to keep the static selection but not have duplication?

Thanks in advance.

If you are using classic asp then you can compare static values in database if they do not match then display the data...


<select>
<%
set rs = Server.CreateObject("ADODB.recordset")
rs.Open "Select * from Customers", conn
do until rs.EOF
    if not rs("fieldname") = "staticfield" then  
       'add the option in select box..
    end if
    rs.MoveNext
loop
%>
--you can add static option here..
</Select>

Hello and thank you. I am not certain how to incorporate that code, especially, the ", conn" part.

Here is my code.

Thank s in advance experts.

<select  name="Header" id="Header">
          <option value="<%=((Recordset1.Fields.Item("Page_Header").Value))%>" selected="selected"><%=((Recordset1.Fields.Item("Page_Header").Value))%></option>
          <option value="Maintenance Notice">Maintenance Notice</option>
          <option value="Systems Down">Systems Down</option>
          <option value="All Systems Go">All Systems Go</option>
        </select>

And to add what I would get as a result shown in dropbox from the above is:

All Systems Go
Maintenance Notice
Systems Down
All Systems Go

The currently selected stuts from the database is "All Systems Go"
But it is repeated.

<%
static_value = split("Maintenance Notice,System Down,All Systems Go",",")
sql = "select Page_Header from tbl"  ' Adjust ur query 
set dr = con.execute(sql)
dim chk_duplicate
chk_duplicate = false
%>

<select distinct name="Header" id="Header">
         
           <% for each static_ind in static_value%>
          <option value="<%=static_ind%>"><%=static_ind%></option>
           <%next%>
          <%
		  while not dr.eof 
		     for each static_ind in static_value
			     if  trim(static_ind) = trim(dr(0)) then 
				    chk_duplicate = true

</select>
