"DESCRIBE" is a command of Oracle's own client - SQL*Plus. When run, it displays the structure of a table i.e. column names, their datatypes, sizes, whether they are nullable or not etc.

I believe fpmurphy wanted you to use that command, rather than plain English, to describe your table.

In any case, you may want to try this Oracle query -

Code:
--
-- This query fetches all records that have LASTOCCURRENCE values between
-- 5-Dec-2010 2:00 PM and 5-Dec-2010 8:00 PM, **both timestamps inclusive**
--
SELECT   node, nodealias, summary, tally, alertkey, alertgroup, manager, agent
   FROM mrtg_alerts
  WHERE lastoccurrence BETWEEN TO_DATE ('5-DEC-2010 14:0:0', 'DD-MON-YYYY HH24:MI:SS')
                           AND TO_DATE ('5-DEC-2010 20:0:0', 'DD-MON-YYYY HH24:MI:SS')
ORDER BY manager DESC;

Note that "between" over here means:
- the timestamp 5-Dec-2010 2:00 PM, and
- all timestamps between 2:00 PM and 8 PM on 5-Dec-2010, and
- the timestamp 5-Dec-2010 8:00 PM

Here's an equivalent query that uses the numeric relational operators instead of BETWEEN -

Code:
-- Equivalent query
SELECT   node, nodealias, summary, tally, alertkey, alertgroup, manager, agent
   FROM mrtg_alerts
  WHERE lastoccurrence >= TO_DATE ('5-DEC-2010 14:0:0', 'DD-MON-YYYY HH24:MI:SS')
    AND lastoccurrence <= TO_DATE ('5-DEC-2010 20:0:0', 'DD-MON-YYYY HH24:MI:SS')
ORDER BY manager DESC;

HTH,

OCI_SET_MODULE_NAME(3)													    OCI_SET_MODULE_NAME(3)

oci_set_module_name - Sets the module name

SYNOPSIS
bool oci_set_module_name (resource $connection, string $module_name) DESCRIPTION
Sets the module name for Oracle tracing. The module name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed. The name can subsequently be queried from database administration views such as V$SESSION. It can be used for tracing and monitoring such as with V$SQLAREA and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE. The value may be retained across persistent connections. PARAMETERS
o $connection -An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3). o $module_name - User chosen string up to 48 bytes long. RETURN VALUES
Returns TRUE on success or FALSE on failure. NOTES
Note Oracle version requirement This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards. Tip Performance With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack- age. This is less efficient than using oci_set_client_info(3). Caution Roundtrip Gotcha Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is enabled. EXAMPLES
Example #1 Setting the module name <?php $c = oci_connect('hr', 'welcome', 'localhost/XE'); // Record the module oci_set_module_name($c, 'Home Page'); // Code that causes a roundtrip, for example a query: $s = oci_parse($c, 'select * from dual'); oci_execute($s); oci_fetch_all($s, $res); sleep(30); ?> // While the script is running, the administrator can see the // modules in use: sqlplus system/welcome SQL> select module from v$session; SEE ALSO
oci_set_action(3), oci_set_client_info(3), oci_set_client_identifier(3). PHP Documentation Group OCI_SET_MODULE_NAME(3)
