Hi All,

I am working on a application in which I have to find the Min and Max time of the user 
session. Since there will be multiple records for a single session with the 
overlapping time. the example data is as foll.

MMCR_APPNO         MMCR_START_TIME      MMCR_END_TIME
------------------ -------------------- ------------------
10000                                10                 30
10000                                20                 40
10000                                40                 45
10000                                10                 50

10000                                60                 80
10000                                70                 90
10000                                65                100

10000                               110                120
10000                               105                140

expected result

MMCR_APPNO         MMCR_START_TIME      MMCR_END_TIME
------------------ -------------------- ------------------
10000                                10                 50
10000                                60                100
10000                               105                140

the comparision has to be done on end time not lying between starttime and endtime of 
the next record if it does then the user belong to same session....

cheers
Swajit
