Average of the difference in date in minutes
Hi friendsI have a table called attendance with 3 columns
eid number
in date
out date
two columns (in, out) of date are stored with date and time. The table will have multiple entriesIs it possible that I can calculate the average of the difference in minutes between in and out of all the records
using a single query or don't we have the right to use the loop.
For Example
eid in out difference in minutes
1 01-01-2012 09:00:00 01-01-2012 10:00:00 60
2 01-01-2012 09:05:00 01-01-2012 10:10:00 65
3 01-01-2012 09:10:00 01-01-2012 10:20:00 80
The result should be the average difference of minutes IE (60 + 65 + 80) / 3 which would be 68.33Thanks in advance

Thank you
Hello
Here's one way:
SELECT ID1
, ADD_MONTHS (start_time, 12 * (LEVEL - 1)) AS start_time value
, ADD_MONTHS (start_time, 12 * LEVEL) AS end_time
id2
FROM table_x
CONNECT BY LEVEL<= months_between="" (end_time,="" start_time)="">=>
AND PRIOR id2 = id2
AND PRIOR SYS_GUID () IS NOT NULL
;
I'm assuming that id2 is unique.
Would what results you if end_time wasn't exactly N years after start_time?

Unlike COUNTY and the difference in data between 2 sets of data
Hey guys,.
I have a question here, probably, it revolves around the UNION, INSERSECT and LESS and maybe something else I'm missing.
I'm two sets of questions, and I have 2 paintings.

Groovy Script to find the difference between Dates
I am trying to build a script that takes a date from a RequestField and calculates the number of days between this date and the current date (from session).
So far, I have a problem, the analysis to-date from the RequestField chain. I found this code but it doesn't seem to work...
date = new Date().parse('yyyy/MM/dd', '1973/07/09')
I get the following error...
Error Message: groovy.lang.MissingMethodException: No signature of method: java.util.Date.parse() is applicable for argument types: (java.lang.String, java.lang.String) values: {"yyyy/MM/dd", "1973/07/09"}
Any help would be greatly appreciated.
Hello
What version of server? The extract you have here works fine on mine (563).
This also works for me
new java.text.SimpleDateFormat('yyyy/MM/dd').parse('1973/07/09')

Don't know if that works better, but instead of using to_char, you could use trunc. Try something like this:
select trunc(some_timestamp,'DD'), avg(parameter1) from bigtable where some_timestamp between systimestamp-180 and systimestamp group by trunc(some_timestamp,'DD');
Hope that helps,

How to get the difference in dates in days
Hi friends,
How to get the date difference between two dates exactly
date2-date1 days exactly... shouyld rounded to the nearest value of...
and one entire display i mean positive integer
Select round ((sysdate) - to_date (date_start)), date_start days of per_periods_of_service
This gives negative also resultHello

Date1 - date2 is the exact number of days is after date2 date1. (It is as accurate as possible, given that the DATEs do not have fractions of a second).
and one entire display i mean positive integer
Select round ((sysdate) - to_date (date_start)), date_start days of per_periods_of_serviceYou want to probably get the exact number of days first, then ROUND this number:
SELECT ROUND (SYSDATE - TO_DATE (date_start, ...)) AS days FROM per_periods_of_service;
Always pass arguments at least 2 to TO_DATE:
(1) the string to be converted, and
(2) a saying string how (1) is formattedThis gives negative also result
Right; If date1 is before date2 then date1 - date2 returns a negative number.
If you want to never get a negative value, use ABS (date2 - date1). If it returns 4, then you know that one of the DATEs was 4 days before the other, but you won't know who was earlier.I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
Explain, using specific examples, how you get these results from these data.
Always tell what version of Oracle you are using. -
Hello
I get 2 different types of data from the controller. How to differentiate b/w them.
After receiving my code in deccissions. There are 6 different control elements in my project attached to the controller. Thanks for give me idea how I send data to the controller for this controller to differentiate that exit to be active or low
First, look at the couple of serial examples that come with LabVIEW. You use the VISA functions to read and write. Your technique to separate the values will work as well in LabVIEW. You would be to convert the string returned by VISA reading to a digital (i.e. with the Scan of the chain). Then do the comparison, then the result of wire to one of the two indicators. Put the terminal of each indicator inside a case statement would be a way to do it.

How to get the difference of two dates in months
Dear friends,
I have 4 items on my page.
2 entered message text (value of loan, monthly deduction)
2 are message style fields (start date, end date)
I need to get the difference from above 2 dates in no.. of months. (for example say N)
So with N, loanvalue should be divided and populated as monthly deduction.
I tried this way, but not able to get the difference of dates
{if ("populateMonthlyDeduction". Equals (PageContext.GetParameter (EVENT_PARAM)))}
System.out.println ("enter populateMonthlyDeduction loop1");
String xxDeductionStartDate = vo.getCurrentRow ().getAttribute("DeducStartDt").toString ();

The output of the table of the ANNEX should be now like this:create table schedule(iloan_code number , schedule_date date); insert into schedule values(1001, to_date('01-jun-2012')); insert into schedule values(1001, to_date('01-jul-2012')); insert into schedule values(1001, to_date('01-aug-2012')); insert into schedule values(1001, to_date('01-sep-2012')); insert into schedule values(1001, to_date('01-oct-2012')); commit;
We want an additional column by name as well as the existing columns DAYS that would be the difference between dates.ILOAN_CODE SCHEDULE_DATE 1001 01-JUN-12 1001 01-JUL-12 1001 01-AUG-12 1001 01-SEP-12 1001 01-OCT-12
First line should be the difference between sysdate as well as the date of June 1, 2012 and successive lines must be the difference between successive calendar date
For example in the second row the DAYS column should represent the difference between 1 July 2012 and 1 June 2012 and so on for the following ranks too.
We need get the result by a SELECT statement
The output of the table in the ANNEX must be something like that.
Please notify;iloan_code schedule_date days Logic which we need 1001 1-Jun-12 22 sysdate-1st June 2012 1001 1-Jul-12 30 difference between 1st July 2012 and 1st June 2012 1001 1-Aug-12 31 difference between 1st aug 2012 and 1st July 2012 1001 1-Sep-12 31 difference between 1st sep 2012 and 1st aug 2012 1001 1-Oct-12 30 difference between 1st oct 2012 and 1st sep 2012
Hello
You can change the Hoek solution like this:
SELECT iloan_code , schedule_date , schedule_date - LAG ( schedule_date , 1 , TRUNC (SYSDATE) ) OVER (ORDER BY schedule_date) AS days_between FROM schedule ORDER BY schedule_date ;
If all schedule_dates will be after SYSDATE, then you need not the CASE expression to test if it is.
The argument optional 3rd to LAG is a return value in case there is no previous line.Sri says:
... The output of the table in the ANNEX must be something like that.iloan_code schedule_date days Logic which we need 1001 30-Jun-12 07 sysdate-30June 2012 1001 1-Jul-12 30 difference between 1st July 2012 and 30 June 2012 ...
The difference between 30 June 2012 and July 1, 2012 is not only 1 day?

The moving average of the data file
Hello
I'm doing a Subvi, which has jumps in the data points.
The algorithm:
-build an array of samples (of size round(FPS/2))
-Take the average
-subtract the data of the table of average points: = absolute difference (medium-sized data point).
-compare the difference threshold: If difference > = point, then add 1 to the counter.
The Subvi (jump detect) is intended to be used in a larger vi, and I need to make sure that it works. But it doesn't now.
When the vi works and everything is calculated, it does not count the jumps that are visible on the ground.
Any ideas what I am doing worng?
Thank you
The exsist problem in your loop in your Subvi. At this stage you are iterating FPS/2 size of the array, and you only show the last value of all of your calculations. Unless the last value is reported as a jump, it will not be saved. You can easily fix this by putting registers at offset on your loop for, the only question is do something with your Boolean indicator. You can index the Boolean values, and then make a chart or works, but this part is up to you.

How to calculate the difference between 2 dates, but with interruptions and stops between
Hello
How can I calculate the difference in minutes between 2 dates but taking into account the existence of a table in the Appendix, so if between start_date and end_date arguments, there is no 'work time' then this part of the time will not be included in the total difference.
Records of the time table example:
Time_configuration start_hour end_day end_hour 2 19:00 3 07:00 3 19:00 4 07:00 so for example first record said that on Monday you start at 19:00 and leave the next day at 7:00 and then save the same sort of thing.
There is an event that I want to track how many minutes lasted. for example, this event began the day 2 at 19:00 and ended the day 3 at 21:00
Theoretically, this event really lasted: 840 minutes. This 840 minutes are within the limits of the annex.
Thanks in advance.
The storage of the dates not as data type DATE in most cases is bad design. In addition, how do you know what day of the date is 2 at 19:00? East - Monday 2 November 2015 or Monday, March 7, 2016? It is the same for the event. In any case, assuming that both calendar and events don't extend over several weeks:
According to schedule)
Select time_configuration 2, 19:00 ' start_hour, end_day 3,' 07:00 ' end_hour of all the double union
Select 3, 19:00 ', 4,' 07:00 ' double
),
event like)
Select event_id 1, time_configuration 2, 19:00 ' start_hour, end_day 3: 21:00 ' end_hour of the double
)
Select e.event_id,
Sum)
less (e.end_day + to_date (e.end_hour, 'HH24'), s.end_day + to_date (s.end_hour, 'hh24:mi')).
greater (e.start_day + to_date (e.start_hour, 'HH24'), s.start_day + to_date (s.start_hour,'hh24:mi'))))
) * 24 * 60 minutes
Appendix s,
e event
where e.start_day + to_date(e.start_hour,'hh24:mi')< s.end_day="" +="">
and e.end_day + to_date(e.end_hour,'hh24:mi') > s.start_day + to_date(s.start_hour,'hh24:mi')
