Hello
Here's one way:
WITH parameters AS
(
SELECT DATE '2011-05-31' AS start_date
, DATE '2011-06-30' AS end_date
, 'Thursday' AS day_o_week
FROM dual
)
, got_dt AS
(
SELECT end_date
, NEXT_DAY ( start_date - 1
, day_o_week
) + (14 * (LEVEL - 1)) AS dt
FROM parameters
CONNECT BY LEVEL <= CEIL ( (end_date - start_date)
/ 14
)
)
SELECT dt
FROM got_dt
WHERE dt <= end_date
;
This ID on NLS_DATE_LANGUAGE load. If you do not what it is, you can change the sub-quewry like this:
WITH parameters AS
(
SELECT DATE '2011-06-25' AS start_date
, DATE '2011-06-30' AS end_date
, TO_CHAR ( DATE '2011-05-30' -- or any Monday
, 'Day'
) AS day_o_week
FROM dual
) ...

Dynamic calculation of the number of days between two dates in a table
Hello
I'm working on request where I dynamically calculate the number of days between two dates in a table.
The calculation must be dynamic, i.e., when I recover the Start_date and End_date and move to the field following (call_duration) in the same row, the difference must be calculated dynamically in this area and make sure the field read-only.
APEX version: 5.0

APEX version: 5.0
one of the way to do this by calling ajax on change of end_date.
See the sample code given below to fetch the resulting duration and making the field read only after calculation
Step 1: Change your page
under CSS-> Inline, put the code below
.row_item_disabled { cursor: default; opacity: 0.5; filter: alpha(opacity=50); pointer-events: none; }
Step 2: Create on demand Ajax process I say CALC_DURATION
Please check Procces Ajax, see line 6.7 How to assign a value to the variable sent by ajax call
Declare p_start_date date; p_end_date date; p_duration number; Begin p_start_date := to_date(apex_application.g_x01); p_end_date := to_date(apex_application.g_x02); --do your calculation and assign the output to the variable p_duration select p_end_date - p_start_date into p_duration from dual; -- return calculated duration sys.htp.p(p_duration); End;
Step 3: Create the javascript function
Change your page-> the function and the declaration of the Global Variable-> put the javascript function
You must extract the rowid in the first place, for which you want to set the time, see line 2
assuming f06, f07 and f08 is the id of the start date, and end date columns respectively, and duration
See no line no 8 how set the value returned by the process of ajax at the duration column
Replace your column to the respective column identifiers in the code below
function f_calulate_duration(pThis) { var row_id = pThis.id.substr(4); var start_date = $('#f06_'+row_id).val(); apex.server.process ( "CALC_DURATION", { x01: start_date,x02: $(pThis).val() }, { success: function( pData ) { // set duration to duration column $('#f08_'+row_id).val(pData); // disable duration column $("#f08_" + row_id).attr("readonly", true).addClass('row_item_disabled'); } }); }
Step 4: choose the end date call the javascript function
Go to report attributes-> edit your Date column end-> column-> Attrbiutes element attributes-> put the code below
onchange="javascript:f_calulate_duration(this);"
hope this helps you,
Kind regards

JavaScript anomaly on the number of days between two dates
Use ApEx 4.0, I found an anomaly in a javascript code that calculates the number of days between two dates, the current_date and the past_date. If the past and present is the or before March 10, 2013, and the current_date lies between 10 March 2013 and November 3, 2013, the number of days will be from 1 day to less than the actual number. Between November 3, 2013 and on 4 November 2013, the increments of number by 2, then the count will be accurate from this date forward.
Here are some examples:
March 10, 2013 = 69 days of December 31, 2012
March 11, 2013 = 69 days of December 31, 2012
March 12, 2013 = 70 days of December 31, 2012
November 3, 2013 = 306 days in December 31, 2012
November 4, 2013 = 308 days in December 31, 2012
11 March should be 70 and 12 March should be 71. November 3 is 307 and 4 November corrects the number of fake, which began March 11.
Change the past_date to March 10, 2013 produces the following:
March 10, 2013 = 0 days of March 10, 2013
March 11, 2013 = 0 days of March 10, 2013
March 12, 2013 = 1 days of March 10, 2013
But change the past_date to 11 March 2013, product of the correct numbers:
March 11, 2013 = 0 days of March 11, 2013
March 12, 2013 = 1 days of March 11, 2013
March 13, 2013 = 2 days of March 11, 2013
I would certainly all help to determine the cause of this anomaly. Here's the javascript code:
var w1 = ($v ("P48_PAST_DATE"));
W1 = (w1.toString ());
vmon var = (w1.substr (3.3));
vyr var = (w1.substr (7));
var r = (vyr.length);
If (r == 2)
vyr. = (parseFloat (vyr) + 2000);
vday var = (w1.substr (0.2));
var y = (vmon.concat ("", vday, ",", vyr));
y = Date.parse (y);
var w2 = ($v ("P48_CURRENT_DATE"));
var vmon2 = (w2.substr (3.3));
var vyr2 = (w2.substr (7));
var vday2 = (w2.substr (0.2));
var x = (vmon2.concat ("", vday2, ",", vyr2));
x = Date.parse (x);
var numdays = (x - y);
numdays = (Math.floor(numdays / 86400000));
$s ("P48_NUMBEROFDAYS", numdays);Did you google for something like "javascript number of days between two dates. I think you will find the explanation to this observation:
This method does not work correctly if there is an advanced economies jump between the two dates.
There are examples available to calculate the difference between two dates.

Calculate the difference in days between two Dates
Hello
I'm trying to understand how to calculate the difference in days between two dates using JavaScript in LiveCycle. (Minimum = JavaScript knowledge)
Where 'Start_Date' and 'Current_Date' are the names of the two dates in the palette of the hierarchy. (the two Date/time field)
* Current date is using the object > value > execution property > current Date/time
I need a text or number field showing the difference in days. (Difference_in_Days)
I noticed the following code is pretty standard among other responses:
var
Start_date = new Date (Start_Date);
var
Current_Date = new Date (Current_Date);
var
nAgeMilliseconds = Current_Date.getTime) - Start_date.getTime ();
var
nMilliSecondsPerYear = 365 * 24 * 60 * 60 * 1000 ;
I know there is lack of code and code above are may not be not correct.
Please notify.
OK, that's because of the way that javascript and works of the calculate event. The field will be filled with whatever the script resolves at the end of execution. Technically, your script does not have a value because the last thing you do is an assignment to a variable. Change the last line as follows:
Math.ABS ((firstDate.getTime)
((- secondDate.getTime (()) / (oneDay));
(eliminate the variable assignment) and get rid of the app.alert. Your script will "return" (have) regardless of the value of calculation from the East and which will be stored in the field.

Calculate the number of days between two dates
Hello
Can someone help please change my formcalc script to calculate the number of working days between two date fields. My script currently calculates the total number of days between two dates, including the weekends which must be excluded from the total.
If
(HasValue (Start_Date1) & HasValue (End_Date1)) then
$
= Date2Num (End_Date1, "YYYY-MM-DD" "en_IE") - Date2Num (Start_Date1, "YYYY-MM-DD" "en_IE") + 1
on the other
""
endif
Any help will be most appreciated.
Thank you.
Check...
(1) you said that you put the script on the event «days1» calculate My sample imitates the variable names used in the original message, "Start_Date1" and "End_Date1". If the names of variables for the start and end dates are different, you will need to modify the script to account for these names.
(2) the Date2Num functions in the calculation of the "totalDays" use the date format "YYYY-MM-DD". If your date habits differ from "YYYY-MM-DD" FormCalc will complain.

Dynamically calculate the number of days between two dates and amounts of split
Hello
I have searched for a solution for this, but had no success.
I need to show the amounts broken down by days.
I have a table that has an amount column and start and end dates.
I need to write a query so that the amounts will be broken evenly based on the number of days between the start date and end date.
For example, for this line.
insert into my_test values (' 1, '' 3-mar-2010, ' 7 - mar - 2010 ", 1000);
the query returns this (split $1,000 over 5 days)
ID Date amount
1 ' 3-mar-2010' 200,00
1 ' 4-mar-2010' 200,00
1 ' 5-mar-2010' 200,00
1 ' 6-mar-2010' 200,00
1 ' 7-mar-2010' 200,00
create table my_test)
ID number (10),
start_date date,
End_date date,
amount number (10.2)
);
Select * from my_test
insert into my_test values (' 1, '' 3-mar-2010, ' 7 - mar - 2010 ", 1000);
insert into my_test values (2, 10-mar-2010 ", 19-mar-2010", 2000);
insert into my_test values (3, 20-mar-2010 ',' 21-mar-2010, 5000);
Thanks in advance.Hello
One way is to join a Meter of Table , a table, or (more often) a set of results includes a line for eery number 1, 2, 3,... until the maximum number of times you need to divide a line.
For example:WITH cntr AS ( SELECT LEVEL - 1 AS n FROM ( SELECT MAX (end_date - start_date) AS max_day_cnt FROM my_test ) CONNECT BY LEVEL <= 1 + max_day_cnt ) SELECT t.id , t.start_date + c.n AS dt , t.amount / (t.end_date + 1 - t.start_date) AS amt FROM my_test t JOIN cntr c ON c.n <= t.end_date - t.start_date ORDER BY id , dt ;
This assumes that all dates have the same number of hours, minutes, and seconds, as is the case in your sample data.
If this isn't the case, then use TRUNC (start_date) and TRUNC (end_date) instead of start_date and end_date or post some sample data and results if some lines do not represent a whole number of days. -
Calculation of the difference in days between two Dates
Hi all
I have two text fields with dates in them (P2_CURRENT_TIME_POINT_TEST_START_DATE, P2_ORGINAL_TEST_START_DATE). I would like to assign another text field (P3_TIME_FROM_INITIAL_TEST), the difference between the two days. I use a calculation page and tried suptracting them right or a date function diff, I found online, but nothing seems to work. Could someone lend me a hand on this one?
Thank you.Ben,
Sorry, please try the following:
:P3_TIME_FROM_INITIAL_TEST := TO_DATE(:P2_CURRENT_TIME_POINT_TEST_START_DATE, 'DD-MON-YYYY') - TO_DATE(:P2_ORGINAL_TEST_START_DATE, 'DD-MON-YYYY');
Remember to substitute the correct format string MON-DD-YYYY.

Behavior of days between two dates
Hello!
If anyone can help? ... with differences in Date? :
All I want is to calculate the number of days between two dates:
InitDate has been entered as 01/10/2010 planning, to recover is 20101001
HireDate was entered into the 1980-10-01 planning, to recover is 19801001
I tried
NumDays = @DATEDIFF (InitDate, HireDate, DP_DAY);
but give me only 0 and -1.
When I try the regular difference:
NumDays = InitDate - HireDate;
He returned to 30,000 (which in the example is 20101001-19801001) - which should not.
I use Essbase/Planning 11.1.1.2, I tried also to break dates in years and months using INT and operations, but when I want to get the calendar days he is ugly. The two dates live in the same block.
Someone at - it an idea?

How to find the difference "within weeks" between two date values?

Any suggestion would be appreciated.
Kind regards

You can use this method to get the number of days between the day and date, and then divided by 7 to get the number of weeks
public static long getDifferenceDaysBetweenTwoDates (d1, d2 oracle.jbo.domain.Date oracle.jbo.domain.Date)
{
If (d1! = null & d2! = null)
{
return (d1.getValue () .getTime () - d2.getValue () .getTime ()) / (24 * 60 * 60 * 1000);
}
return 0;
