//                       clob_col CLOB, date_col DATE);

$conn oci_connect("hr""hrpwd""localhost/XE");
if (!
$conn) {
    
$m oci_error();
    
trigger_error(htmlentities($m['message']), E_USER_ERROR);
}

$stid oci_parse($conn"SELECT * FROM mytab");
oci_execute($stidOCI_DESCRIBE_ONLY); // Use OCI_DESCRIBE_ONLY if not fetching rows

echo "<table border=\"1\">\n";
echo 
"<tr>";
echo 
"<th>Name</th>";
echo 
"<th>Type</th>";
echo 
"<th>Length</th>";
echo 
"</tr>\n";

$ncols oci_num_fields($stid);

for (
$i 1$i <= $ncols$i++) {
    
$column_name  oci_field_name($stid$i);
    
$column_type  oci_field_type($stid$i);
    
$column_size  oci_field_size($stid$i);

    echo 
"<tr>";
    echo

    echo 
"<td>$column_type</td>";
    echo

    echo 
"</tr>\n";
}

?>

Note

Nota:

In PHP versions before 5.0.0 you must use ocicolumntype() instead. This name still can be used, it was left as alias of oci_field_type() for downwards compatability. This, however, is deprecated and not recommended.
