I am getting daily basis data from third party in excel format which i am converting into CSV format and then uploading into oracle tables using External tables.Now problem is that every time i getting the dates in diff format i.e. sometimes dd-mon-yyyy , dd/mm/yyyy etc.
Now every time i have to open my code and change it there ...to make it as oracle date format. IS there way i can find out format of date and based on format i can do operations with getting errors every time.
I am storing the TP(Excel date) date into varchar columns only and then varchar2 column value i m inserting/updating into date format using to_Date ().

I have two tables
table_1
--Emp_id--|--Sup_id--|Sup_name|--Date--|
-------------------------------------------------
--00001--|--00005 --|---ABCD--|01-MARCH-2004
--00002--|--00006 --|---BCDE--|02-MARCH-2004
--00003--|--00007 --|---CDEF--|03-MARCH-2004
--00001--|--00008 --|---DEFG--|04-APRIL-2004
--00003--|--00009 --|---EFGH--|05-APRIL-2004
table_2
--Emp_id--|Emp_name|
--------------------------------
--00001--|--QWER--|
--00002--|--ASDF--|
--00003--|--ZXCV--|
--00004--|--POIU--|
table_1 contain records on employee and the supervisor they are under at a certain date.
As some employee(00001 & 00003) have a different supervisor from different date, I'll like to extract from table_1 the record of each employee in the table that only contain the supervisor info on the most recent date.And from table_2, i'll like to extract the employee's name. These records extracted from both the tables would the be put into a new table,table_3
Example: For employee 00001, only extract record that have the most recent date which is 04-APRIL-2004 and not on 01-MARCH-2004
table_3
Emp_id|Emp_name|Sup_id|Sup_name|Date|
------------------------------------------------
00001 |--QWER--|00008 |--DEFG---|04-APRIL-2004
00002 |--ASDF-- |00006 |--BCDE---|02-MARCH-2004
00003 |--ZXCV-- |00009 |--EFGH---|05-APRIL-2004

we can easily find out the locks which are currently active session.
Is any other way to find out locks on particular date and time using data dictionary?
For example, we have to find whether TT_objects occured the lock or not on ON yesterday.

My table has two date columns EFF_DT which is the start date and TERM_DT is the end date. The EFF_DT of the next record should be the next date of the TERM_DT record.
My table looks like this.
Input Table:
-----------
CK_IDPI_IDEFF_DT TERM_DT
Mem1ABC1-Jan-1331-Mar-13
Mem1ABC1-Apr-1331-May-13
Mem1ABC1-Jun-1330-Sep-13
Mem1ABC15-Oct-1331-Dec-13
Mem1ABC1-Jan-1431-Mar-14
Mem1XYZ1-Apr-1430-Jun-14
Mem1XYZ1-Jul-1431-Dec-14
Expected Output:
----------------
CK_IDPI_IDEFF_DT TERM_DT
Mem1ABC1-Jan-1330-Sep-13
Mem1ABC15-Oct-1331-Mar-14
Mem1XYZ1-Apr-1431-Dec-14
In the fourth record, the effective date should be 1-Oct-13 which is the next date to the last TERM_DT 30-Sep-13.As the is the break in the date, the output should show 15-Oct-13 sa the second start date.
Note: Refer to the PI_ID columns, there is a break in the date for the sale PI_ID 'ABC'.
Here I am trying to generate a pseudo column, so that the table with the pseudo column looks like as shown below. and I can use first_value and LAST_value by partitioning on the pseudo column to get the desired output.
1) CNT_VAL is the pseudo column:
-----------------------------
CK_IDPI_IDEFF_DT TERM_DT CNT_VAL
Mem1ABC1-Jan-1331-Mar-131
Mem1ABC1-Apr-1331-May-131
Mem1ABC1-Jun-1330-Sep-131
[code].....
My Query :
----------
I not getting the desired output here as the value in pseudo column is 3.
select CK_ID, PI_ID,EFF_DT,TERM_DT,
(case
when case_CONT - LAG(case_CONT,1) over (ORDER BY EFF_DT) = 0 then to_char(case_CONT)
when case_CONT - LAG(case_CONT,1) over (ORDER BY EFF_DT) <> 0 then to_char(LAG(case_CONT,1) over (ORDER BY EFF_DT) + 1)
else to_char(nvl(case_CONT,0))
[code].....
Scripts:
--------------------
Create table lead_test(
CK_ID varchar2(10),
PI_IDvarchar2(10),
EFF_DTDate,
TERM_DT date);
[code].....

The requirement is to find the last date when either ATTRIB1 or ATTRIB2 were modified for each ID. There are many other columns in the table, but I'm not interested in other columns.
Test Case
SET LINES 100
SET PAGES 100
DROP TABLE test_log
/
CREATE TABLE test_log
[code]....
Expected Output
ID LAST_CHANGE_DATE
---------- --------------------
11 02-SEP-2012 10:58:32
35 05-AUG-2012 10:58:32
I have written the below query, to get the required output.
SELECT MAX(i_date) last_change_date
FROM
(
SELECT seq,id, attrib1, attrib2, i_date,
row_number() OVER (PARTITION BY attrib1 ORDER BY i_date) rn1,
row_number() OVER (PARTITION BY attrib2 ORDER BY i_date) rn2

Lets say I have a table,
Claim_id,dateA,dateB
it has 5 million rows
I need to see if any dateA,dateB of a claim_id falls within any other dateA,dateB of another claim ID
Basically
select * from table a, table b, where
(a.dateA,a.dateB) overlaps (b.dateA,b.dateB)
now I can write the query simply enough by aliasing the table 2x but no matter how I try I cant see a way to get around doing a Carteasion join
Index are ignored because it has to scan the full table anyway even if I hint the index
and the cost of the join ends up astronomical aka 5million rows X 5 million Rows....
And it ends up doing the full table scan a few times
AHHHHHHHHHHHHHHHHHH
this table is expected to grow to at least 20 million records

I have to create a function. I need to find the max last logout date for each agent daily. For example, if an agent logged in for the first time at 9:00 and he logged out at 12:00 and he logged in again in 14:00 and he logged out at 15:00 the time I need my report to show is 15:00. How can I do that?In order to make it easiest for you to understand I am sending you this query:
select
a.login as login2,
To_Char(max(s.endtime), 'dd/MM/yyyy, HH24:MI:SS') as lastLogout
from cti.agent a
inner join cti.agentsessionlog s
on s.agentid = a.agentid and To_Char(s.endtime) != '31-DEC-99 11.59.59.000000 PM'
group by a.login;
This query returns the agent's login and the agent's last logout time. It works fine if I enter a date between but I cannot do that. If a use this query as it is and I try to export a report for 31/5 it shows as lastlogout the logout for 01/06 or 2/06. Is there a function I can use? I have a deadline.

How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.

And display the data like this:

125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09
As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.
