Using oci_fetch on dual is returning nothing.

Question

I am prototyping some PHP to Oracle applcations. I have a simple connection setup to fetch data on of dual, but nothing is being returned. The connection is occurring since no errors are generated.
               <?
               print'<tr>';
                    $db='(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ike.arsc.uscg.mil)(PORT = 1521))
                         (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=attest.arsc.uscg.mil)))';
                    $conn = oci_connect("scott","tiger",$db) or die;
                    if (!$conn)
                         $e = @oci_error();
                    $stmt = @oci_parse($conn, "select * from dual");
                    if (!$stmt)
                         $e = @oci_error($conn); // For oci_parse errors pass the connection handle
                         echo htmlentities($e['message']);
                         echo "<td>Broke</td>";
                    $r = @oci_execute($stmt);
                    if (!$r)
                         $e = @oci_error($stmt); // For oci_execute errors pass the statementhandle
                         echo htmlentities($e['message']);
                         echo "<td>Broke</td>";
                    while (@oci_fetch($r))
                                        print '<td>---- data ----</td>';
                         print '<td>'. ociresult($stmt).'</td>';
                    print '<td>test</td>';
                    print '</tr>';
               ?>
What am I doing wrong?

Answer 1

This will work for you:
<?php
// Connect to the database.
if ($c = @oci_connect("<i>username</i>","<i>passwd</i>","<i>oracle_sid</i>"))
// Parse a query to a resource statement.
$s = oci_parse($c,"SELECT * FROM dual");
// Execute query without an implicit commit.
oci_execute($s,OCI_DEFAULT);
// Read fetched headers.
for ($i = 1;$i <= oci_num_fields($s);$i++)
print oci_field_name($s,$i).'&lt;br /&gt;';
// Read fetched data.
while (oci_fetch($s))
for ($i = 1;$i <= oci_num_fields($s);$i++)
print oci_result($s,<b>$i</b>).'&lt;br /&gt;';
// Disconnect from database.
oci_close($c);
else
// Assign the OCI error and format double and single quotes.
$errorMessage = oci_error();
print htmlentities($errorMessage['message'])."&lt;br /&gt;";
?>
