The GetString() method allows you to display the string with only one Response.Write. It also eliminates the do...loop code and the conditional test that checks if the recordset is at EOF.
Syntax
str = rs.GetString(format,rows,coldel,rowdel,nullexpr)
To create an HTML table with data from a recordset, we only need to use three of the parameters above (all parameters are optional):
- 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
In the following example we will use the GetString() method to hold the recordset as a string:
Example
<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>
<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>
The str variable above contains a string of all the columns and rows returned by the SQL SELECT statement. Between each column the HTML </td><td> will appear, and between each row, the HTML </td></tr><tr><td> will appear. This will produce the exact HTML we need with only one Response.Write.
