Do wordpress support Oracle 10g or 8i

No it doesn’t support oracle

you need MySQL 4.1.2 or greater

I wonder as Oracle have now bought sun if this will ever happen!

And Oracle also owns MySQL (kind of).

But here’s an article that has some info though not necessarily Oracle: Using_Alternative_Databases

It depends on what you plan on doing; to run WordPress I would stick with MySQL, but since PHP can talk with Oracle through OCI8, you can use this function to make a connection, do a query and show the results (example uses the Resources schema that comes with Oracle Express):

function MyOracleConnection ()

{
$conn = oci_connect('hr', 'tester', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
	}
	else	{
	echo '<p>Congrats: Oracle meets WordPress!</p>';
}

// Prepare the statement
$stid = oci_parse($conn, 'SELECT * FROM departments');
if (!$stid) {
    $e = oci_error($conn);
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

// Perform the logic of the query
$r = oci_execute($stid);
if (!$r) {
    $e = oci_error($stid);
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

// Fetch the results of the query
print "<table border='1'>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
    print "<tr>\n";
    foreach ($row as $item) {
        print "    <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : "&nbsp;") . "</td>\n";
    }
    print "</tr>\n";
}
print "</table>\n";

oci_free_statement($stid);
oci_close($conn);
}

You can then use this function in your WordPress template to do the magic.

Tibor,

You do that magic?

Tibor, you helped me so much =D
Thanks!
