I don't think this should be as hard as I am making it. I want to select the
earlier of all records that have the same message. There is a bit of
extraneous data in here but I'm lazy and it was easier to leave it in so my
apologies for that. I hope this formats ok.
CREATE TABLE "JOE" ( "ID_ACTIVITY" NUMBER(10),
"CREATED_USERNAME" VARCHAR2(100),
"OWNER_USERID" VARCHAR2(100),
"CREATED_TIME" TIMESTAMP(6),
"CATAGORY" VARCHAR2(8),
"MESSAGE" VARCHAR2(2000));
insert into joe values (61061, 'bill@xxxxx', 'fred@xxxxx', to_date('07-May-2009
01:00:00', 'DD-MON-YYYY HH24:MI:SS'), 'request', 'Message1');
insert into joe values (61061, 'bill@xxxxx', 'nelson@xxxxx',
to_date('08-May-2009 02:00:00', 'DD-MON-YYYY HH24:MI:SS'), 'request',
'Message1');
insert into joe values (160172, 'sam@xxxxx', 'bill@xxxxx', to_date('25-Sep-2009
06:35:00', 'DD-MON-YYYY HH24:MI:SS'), 'request', 'Message2');
insert into joe values (160172, 'bill@xxxxx', 'meywr@xxxxx',
to_date('25-Sep-2009 07:44:00', 'DD-MON-YYYY HH24:MI:SS'), 'request',
'Message2');
insert into joe values (818035, 'blah@xxxxx', 'bill@xxxxx',
to_date('31-Aug-2011 02:22:00', 'DD-MON-YYYY HH24:MI:SS'), 'request',
'Message3');
insert into joe values (818035, 'bill@xxxxx', 'kilburn@xxxxx',
to_date('31-Aug-2011 02:32:00', 'DD-MON-YYYY HH24:MI:SS'), 'request',
'Message3');
insert into joe values (824115, 'nobody@xxxxx', 'bill@xxxxx',
to_date('12-Sep-2011 11:40:00', 'DD-MON-YYYY HH24:MI:SS'), 'request',
'Message4');
insert into joe values (824115, 'bill@xxxxx', 'kilburn@xxxxx',
to_date('13-Sep-2011 01:31:00', 'DD-MON-YYYY HH24:MI:SS'), 'request',
'Message4');
select * from joe;
1. 61061 bill@xxxxx fred@xxxxx 07-MAY-09
01.00.00.000000000 AM request Message1
2. 61061 bill@xxxxx nelson@xxxxx 08-MAY-09
02.00.00.000000000 AM request Message1
3. 160172 sam@xxxxx bill@xxxxx 25-SEP-09
06.35.00.000000000 AM request Message2
4. 160172 bill@xxxxx meywr@xxxxx 25-SEP-09
07.44.00.000000000 AM request Message2
5. 818035 blah@xxxxx bill@xxxxx 31-AUG-11
02.22.00.000000000 AM request Message3
6. 818035 bill@xxxxx kilburn@xxxxx 31-AUG-11
02.32.00.000000000 AM request Message3
7. 824115 nobody@xxxxx bill@xxxxx 12-SEP-11
11.40.00.000000000 AM request Message4
8. 824115 bill@xxxxx kilburn@xxxxx 13-SEP-11
01.31.00.000000000 AM request Message4
So, I am looking for a statement that would return rows 1, 3, 5, and 7. I have
tried various things with min(created_time) but that is too limiting since I
only get one row (duh).
Any/all pointers/tips welcome.
thanks,
-joe
