<h1>ADO Recordset</h1>

<p class="intro">To be able to read database data, the data must first be loaded
into a
recordset.&nbsp;</p>
<hr />
<h2>Create an ADO Table Recordset</h2>
<p>After an ADO Database Connection has been created, as demonstrated in the
previous chapter, it is
possible to create an ADO Recordset.&nbsp;&nbsp;</p>
<p>Suppose we have a database named &quot;Northwind&quot;, we can get access to the
&quot;Customers&quot; table inside the database with
the following lines:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
  <tr>
    <td>
      <pre>&lt;%
set conn=Server.CreateObject(&quot;ADODB.Connection&quot;)
conn.Provider=&quot;Microsoft.Jet.OLEDB.4.0&quot;
conn.Open &quot;c:/webdata/northwind.mdb&quot;</pre>
      <pre>set rs=Server.CreateObject(&quot;ADODB.recordset&quot;)
rs.Open &quot;Customers&quot;, conn
%&gt;</pre>
    </td>
  </tr>
</table>
<br />
<hr />
<h2>Create an ADO SQL Recordset</h2>
<p>We can also get access to the data in the &quot;Customers&quot; table using
SQL:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
  <tr>
    <td>
      <pre>&lt;%
set conn=Server.CreateObject(&quot;ADODB.Connection&quot;)
conn.Provider=&quot;Microsoft.Jet.OLEDB.4.0&quot;
conn.Open &quot;c:/webdata/northwind.mdb&quot;</pre>
      <pre>set rs=Server.CreateObject(&quot;ADODB.recordset&quot;)
rs.Open &quot;Select * from Customers&quot;, conn
%&gt;</pre>
    </td>
  </tr>
</table>
<br />
<hr />
<h2>Extract Data from the Recordset</h2>
<p>After a recordset is opened, we can extract data from recordset.&nbsp;&nbsp;</p>
<p>Suppose we have a database named &quot;Northwind&quot;, we can get access to the
&quot;Customers&quot; table inside the database with
the following lines:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
  <tr>
    <td>
      <pre>&lt;%
set conn=Server.CreateObject(&quot;ADODB.Connection&quot;)
conn.Provider=&quot;Microsoft.Jet.OLEDB.4.0&quot;
conn.Open &quot;c:/webdata/northwind.mdb&quot;</pre>
      <pre>set rs=Server.CreateObject(&quot;ADODB.recordset&quot;)
rs.Open &quot;Select * from Customers&quot;, conn</pre>
      <pre>for each x in rs.fields
   response.write(x.name)
   response.write(&quot; = &quot;)
   response.write(x.value)
next
%&gt;</pre>
    </td>
  </tr>
</table>
<br />
<hr />
<h2>The ADO Recordset Object</h2>
<p>The ADO Recordset object is used to hold a set of records from a database table.&nbsp;</p>
<p><a href="ado_ref_recordset.asp">View all methods and properties of the Recordset object</a>.</p>
