Ok first I created one table:
</p>
<p>
CREATE TABLE TEMP1234( <br>
     location     VARCHAR2(6),<br>
     date_start     DATE<br>
);<br>
</p>
<p>
ALTER SESSION SET NLS_DATE_FORMAT='YYYY/MM/DD';
</p>
<p>
INSERT into TEMP1234 values ('l1', '2006/10/01');<br>
INSERT into TEMP1234 values ('l1', '2006/10/20');<br>
INSERT into TEMP1234 values ('l1', '2006/11/01');<br>
INSERT into TEMP1234 values ('l2', '2006/11/03');<br>
INSERT into TEMP1234 values ('l2', '2006/11/19');<br>
INSERT into TEMP1234 values ('l1', '2006/11/28');<br>
INSERT into TEMP1234 values ('l1', '2006/12/10');<br>
<br>
COMMIT;
</p>
<p>
Now once it is done, now issue following SQL.
</p>
<p>
SELECT location, date_start, (MAX(date_start) OVER ( order by date_start rows <br>between current row and 1 following)) as date_end<br>
FROM TEMP1234<br>
ORDER BY date_start<br>
</p>
<p>
Result will be as follows:<br>
</p>
<p>
LOCATI DATE_START DATE_END<br>
------ ---------- ----------<br>
l1 2006/10/01 2006/10/20<br>
l1 2006/10/20 2006/11/01<br>
l1 2006/11/01 2006/11/03<br>
l2 2006/11/03 2006/11/19<br>
l2 2006/11/19 2006/11/28<br>
l1 2006/11/28 2006/12/10<br>
l1 2006/12/10 2006/12/10<br>
</p><br>
<p>
7 rows selected.<br>
</p>
<p>
I hope this will solve your problem.
