Hi List,

I have the below query which returns 13 records.  In this I want to display
only the 1st row.  Is it possible to do this through rownum or any other
function or pseudo column?  If so, please let me know the same.  Any help in
this regard is very much appreciated.

select 'shipment' table_name,ce.display_name,st.timestamp, sequence 
from shipment_timestamp st, customer_event ce, xm_field xm 
where shipment_id = 10402344721477 
and ce.CUSTOMER_MOT_ID = 1040130035205
and xm.field_id = ce.field_id
and st.event_id = xm.event_id
union
select 'container' table_name,ce.display_name,sct.timestamp, sequence  
from shipment_container_timestamp sct, customer_event ce, xm_field xm 
where shipment_id = 10402344721477 
and ce.CUSTOMER_MOT_ID = 1040130035205
and xm.field_id = ce.field_id
and sct.event_id = xm.event_id
union
select 'order' table_name,ce.display_name,ot.timestamp, sequence  
from order_timestamp ot, shipment_order so,customer_event ce, xm_field xm 
where so.shipment_id = 10402344721477 
and so.order_id = 2
and ot.shipment_order_id = so.shipment_order_id  
and ce.CUSTOMER_MOT_ID = 1040130035205
and xm.field_id = ce.field_id
and ot.event_id = xm.event_id order by sequence desc 

Thanks and Regards,

Ranganath
