1 reject 01/01/2016 01/02/2017 03/04/2009
2 approve 03/02/2013 03/04/2008 02/02/2012
3 in progress 03/02/2014 04/05/2016 06/05/2013
itemcode
1 abs
2 edf
3 esd
now here what i am doing is
select itemno,item code,closedate
from item a join itemcode b
on a.itemno= b.itemno
where a.itemdesc ='aprove'
select itemno,item code,opendate
from item a join itemcode b
on a.itemno= b.itemno
where a.itemdesc ='inprogress '
select itemno,item code,eventdate
from item a join itemcode b

Use OR/IN in the your WHERE clause.

SELECT itemno,item code,closedate FROM item a INNER JOIN itemcode bFROM item a INNER JOIN itemcode b ON a.itemno= b.itemnoON a.itemno= b.itemno WHERE a.itemdesc IN *('approve', 'in progress', 'received');WHERE a.itemdesc IN *('approve', 'in progress', 'received');

Why not make things easy for everyone and tell us all what your expected output is given the data you have already provided?

maybe something like:
SELECT a.itemno, b.itemcode, CASE a.itemdesc WHEN 'aprove' THEN a.closedate WHEN 'inprogress' THEN a.opendate WHEN 'reject' THEN a.eventdate END AS evemtdate FROM item a INNER JOIN itemcode b ON a.itemno = b.itemno WHERE a.itemdesc IN ('aprove', 'inprogress', 'reject')
