SQL & PL/SQL :: Date Overlap And Merge Date Query
May 11, 2011
Lets say the contents of the table are like this -
key dte_start(number) dte_end(number)
1 20010101 20011231
1 20020101 20081231
1 20030601 20071231
1 20100101 20101231
2 20090101 20091231
2 20090401 20101231
2 20101231 20111231
2 20140101 20141231
3 20080101 20091231
3 20070101 20081231
3 20100101 20101231
3 20120101 20120630
I want the query to resolve overlapping dates as well as merge contiguous segment and leave non-contiguous segments as is. The final result of the query should be like this.
key dte_start(number) dte_end(number)
1 20010101 20081231
1 20100101 20101231
2 20090101 20111231
2 20140101 20141231
3 20070101 20101231
3 20120101 20120630
I tried using the lead over partition along with the standard overlap query and case logic to get the results but couldn't get it to work.

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 this requirement to pull the ACTIVE days that a participant holds true in a given month for a specific position he/she holds.
The three date ranges here are: LOA dates(leave of absence), XFER dates(TRANSFER in/out of the position),Quality compliance(QUAL start/end dates).
So,
INACTIVE DAYS = [(LOA + XFER + WW) - OVERLAPPING DAYS OF (LOA+XFER+QUAL)]
Here is the scenario:
---------------------
CREATE TABLE PAYEES
(
RUN_PERIOD DATE NOT NULL,
PAYEEID VARCHAR2(20 BYTE) NOT NULL,
LOA_START_DATE DATE,
LOA_END_DATE DATE,
[Code].....
---------------------------------------------------------
---------------------------------------------------------
Now Active days is to be pulled for Two payees - TESTD01 and TESTD02 for the period of June month.
Desired Results :
Payee InActive_days Active_Days Period
---------------------------------------------------------------------------------------
TESTD01 13 17 June
TESTD02 14 16 June
I am able to pull out the no of days on a individual basis(count of days for Xfer/LOA/Qual) but I am really not sure as to how should i go about determining the overlapping days between 3 date ranges to determine the ACTIVE/INactive days.

When I run a query form the the Query Window in Visuial Studios 2012 all the date fields truncated to 'mm/dd/yyyy', but i need the full date returned. I am able to get full date from TO_char(MyDateField, 'yyyy-mm-dd hh24:mi:ss'), but if I do TO_DATE(MyDateField, 'yyyy-mm-dd hh24:mi:ss') it only returns 'mm/dd/yyyy'. I'm sure this is a simple setting in Visual studios but I cant find it to save my life. Is there there a way to have the full date returned by default?

I'm trying to work out how to take a table like this:
IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09
And display the data like this:
IDPeriodPeriod StartPeriod End
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.

How to get the payment date less than the sch date?
example:
1) for 07/24/2012 sch date the nearest payment date is 07/27/2012.
sch date should be less than the payment date.
Sch dates 07/24/2012 and 07/26/2012 are less than payment date 07/27/2012 but we take the least one.
2) sch date 07/27/2012 is less than the payment date 08/08/2012 so 07/27/2012
Below is the scripts and output needed.
create table cust_sch_tbl
(
customer_NUMBER number,
c_CODE char(5),
sch_DATE date
);
[Code]...
Output needed:
cust cust code payment date sch date
4611 c1 7/27/2012 7/24/2012
4611 c1 8/8/2012 16:57 7/27/2012
4611 c1 10/19/2012 16:37 10/11/2012

Version : 4.1.1, I have a tabular form on a DB table. One of the columns is a date field. When the user hits the "add Row" button on the tabular form, I want the Date field to be defaulted to sysdate. Here is what I have tried so far,
1. Created a "hidden" item P1_SYSDATE and populated the default value with sysdate. After this, under the DB tabular report date field, I used default type - Item/application on this page and entered P1_sYSDATE
2. Instead of populating the default value of the P1_SYSDATE hidden item, I created a before regions process and added
:P1_SYSDATE := sysdate
and added P1_SYSDATE to default type of the tabular date field with default type as "ITem/application on this page.
I get the error
ORA-01790: expression must have same datatype as corresponding expression
I tried to_Char(sysdate,'dd-mon-yyyy') and then converting it back to to_date. still no luck.

Write a program to declare a date variable and assign it to the current system date. Depending on the day of the month the program should print the following:
If day is 1-10 then print "It is day<day number> of <month name>. It is early in the month".
If day is 11-20 then print "It is day<day number> of <month name>. It is the middle of the month".
If day is 21-31 then print "It is day<day number> of <month name>. It is nearly the end of the month".
For example, if the day is November 30, then print "It is day 30 of November. It is nearly the end of the month".

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.

I have a small prolem thats best described like this....
a table called TONY with a field named VISITED (date as YYYYMMDD).
We want to populate the field TIMESTAMP (Last visited timestamp, 18 digits) using midnight or 00:00:00 on VISITED value.
Something like:
UPDATE TONY SET TIMESTAMP = �(whatever the formula is involving VISITED).
but i cannot figure out the best way to derive the TIMESTAMP value...
it's a date to epoch conversion, and i can find many examples of Epoch to date, but thats the wrong way around for me i'm afraid!
Oracle 11gR2 by the way...

DBMS_OUTPUT.PUT_LINE('The new date format is : '|| v_latest_close);

I need to convert the type of GMT to Local time, during data entry. I have a source table and a target table.
To make the insert get the most value, I have no problems:
insert into destination (SELECT * FROM WHERE source pointnumber = (SELECT MAX (pointnumber) FROM source));
But since times are different between the tables, I want to convert the data obtained to GMT -4:30 Time (Caracas - Venezuela), before inserting it.
I can use a function?

I am having problems with the XMLTable function. I cant get it to see the entire date/time value in a date field. This wont work
select x1.* from XMLTABLE('/DOCUMENT' passing xmltype('<DOCUMENT><STR>abc def ghi</STR><NUM>1234</NUM><DT>2013-02-17T04:24:02</DT></DOCUMENT>') columns STR varchar2(25), NUM number, DT date) x1;
However if I change the DT tag to just the date only "2013-02-17" it works. Why wont Oracle see the entire date/time format even if its ISO 8601 compliant?

We have one oracle table, which has one column "Creation_Date" of the datatype date.
This column has data like
"14-Aug-2010 01:30:30"
"14-Aug-2010 03:30:30"
"15-Aug-2010 01:30:30"
"16-Aug-2010 01:30:30"
"16-Aug-2010 03:30:30"
We want to write SQL query which will group rows by date wise without considering time..I mean for above rows the date wise output should be
Count Date

I have a query with a few tables in join, and I filter data with something like
where mytable.initial_date > sysdate-30
If I use any date, it takes about 5 seconds to run, but if I use
to_date('01010001','ddmmrrrr')
instead of any other dates, it takes just a few milliseconds. Now, it's just a curiosity, but why that date makes the query VERY fast? Does Oracle treat it in some special way? Maybe it knows every date is greatest than that date and doesn't consider the filter?
