I know how to select the last N sets of rows, using DENSE_RANK - where multiple rows have the same timestamp but I want to only select those rows which do NOT have the top 2 unique timestamps.
i.e.:
SELECT *
FROM ( SELECT DENSE_RANK() OVER (ORDER BY myTimestamp DESC) DENSE_RANK, HISTORYID, USER_ID, myTimestamp, STATUS, FROM TXN_HIST)
WHERE DENSE_RANK > 2 order by myTimestamp DESC, HISTORYID, USER_ID;
But how do I DELETE these same rows?
My homework requires me to create a booking table for a hotel and I have created the table but I'm having trouble inserting the dates.
This is my table:
DROP TABLE BookingDM CASCADE CONSTRAINTS PURGE;
CREATE TABLE BookingDM (
hNo NUMBER(3),
gNo NUMBER(5),
dFrom DATE NOT NULL,
[code]......
This is the first set I'm attempting to insert
hNo = 148
gNo = 11169
dFrom = 09/03/2009
dTo = 09/10/2009
rNo = 202
This is my attempt to insert the set:
SQL> INSERT INTO BookingDM VALUES('148', '11169', '09/03/2009', '09/10/2009', '202');
INSERT INTO BookingDM VALUES('148', '11169', '09/03/2009', '09/10/2009', '202')

we have to split the date by 7 days,should be on Sunday...and if we split by 7 days we have upto 31/01,07/02 and 14/02...but we have to generate 6 days because 20,10,10,15,25,20 (since comma separated value is 6 ).
I want to find the dates which have a date plus with in 2 days after this date. I mean group by 3 days each even the date i missing between two days. Actualy I want to find the start date where the employ was missing on job.
Basic concept is employes have allowed to use 10 personal leaves of a year. Each leave can be use for maximum 3 days.
If employ did not come on the job for one day or two days or three days, it shoul be count as ONE personal leave. And If employ is missing at job for four or five days, it should be count as 2 personal leaves.

After finding these days I want to select the starting date of 5th personal leave. (which is 16.01.10).
I am not a expert of using SQL, but I think it could be possible with using partitioning a table on the givin reslult and further partition the reslut on rownum() as rn and the using case statement where rn = 5.
Split a date into new dates according to black out dates!
Here is my tables:
CREATE TABLE travel
(
start_date,
end_date
)
AS
SELECT DATE '0000-01-01', DATE '9999-12-31' FROM DUAL;
[code]....
I have lets say a "travel date" and black out dates. I will split the travel date into pieces according to the black out dates.
Note: Travel Date can be between 0000-01-01 - 9999 12 31
Sample:
Travel Date:
Travel | START DATE | END DATE
T | 2011 01 04 | 2011 12 11
Black Out Dates:
BO | START DATE | END DATE
A | 2010 11 01 | 2011 02 11
B | 2011 01 20 | 2011 02 15
C | 2011 03 13 | 2011 04 10
D | 2011 03 20 | 2011 06 29
Excepted Result:
New Travel | START DATE | END DATE
X1 | 2011 02 16 | 2011 03 12
X2 | 2011 06 30 | 2011 12 11
Visually:
Travel Date : -----[--------------------------]--
A : --[------]-------------------------
B : ------[---]------------------------
C : --------------[---]----------------
D : ----------------[------]-----------
Result :
X1 : -----------[--]--------------------
X2 : -----------------------[--------]--
Sample 2:
Travel Date : -[--------------------------------]--
BO Date A : ----[------]-------------------------
BO Date B : -------------------------[---]-------
BO Date C : ----------------[---]----------------
BO Date D : ------------------[------]-----------
Result X1 : -[-]-------------------------------
Result X2 : -----------[--]--------------------
Result X3 : -----------------------------[--]--
