PL SQL help
Anyone that could confirm if this is possible would be great,

I have a table with the following columns

EMPLOYEEID NUMBER(12,0)
PUNCHDTM DATE
TIMEZONEID NUMBER(12,0)

I want to return any results where any employee id that has 2 different timezoneid's on the same date. I would actually like, if its possibe, to select these etnries to display on one row per employee per day. So for example

EMPLOYEEID - PUNCHDTM - TIMEZONEID - PUNCHDTM - TIMEZONEID
12345 - 6/20/2012 5:00 am - 123 - 6/20/2012 10:00am - 456

To me who is newer with SQL this sounds like i would be 'joining' the table to itself so i've searched for that but not found what i need.

Thank you in advance for any help

This should get you started:
Code:
select e1.employeeid, 
       e1.punchdtm,
       e1.timezoneid,
       e2.punchdtm,
       e2.timezoneid
from a_table e1
  join a_table e2 
       on e1.employeeid = e2.employeeid 
      and e1.timezoneid <> e2.timezoneid

Note that this won't work correctly if an employee has more than 2 timezones.
