Example
To create an HTML table with data from a recordset, we only need to use three of the parameters above:
- coldel - the HTML to use as a column-separator
- rowdel - the HTML to use as a row-separator
- NullExpr - the HTML to use if a column is NULL
Note: The GetString() method is an ADO 2.0 feature. You can download ADO 2.0 at
http://www.microsoft.com/data/download.htm.
In the following example we will use the GetString() method to hold the
recordset as a string:
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"
set rs = Server.CreateObject("ADODB.recordset")
rs.Open "SELECT Companyname, Contactname FROM Customers", conn
str=rs.GetString(,,"</td><td>","</td></tr><tr><td>"," ")
%>
<table border="1" width="100%">
<tr>
<td><%Response.Write(str)%></td>
</tr>
</table>
<%
rs.close
conn.close
set rs = Nothing
set conn = Nothing
%>
</body>
</html>
