Calculation of the time differences between several lines
HelloI have a table as below:
EVENT ID DATE
1. start 05/03/2012-13:00
1. stop the 15:00 05/04/2012
1. start 09:00 05/07/2012
1 stop on 05/09/2012 10:00
Start 2 08/06/2012-08:00
2 stop on 08/07/2012 10:00
I would like to calculate the duration (in hours ideally) between 'Start' and 'Stop' for each ID, so having a set of lines:
ID TimeSpan
---------------------
1 75
26 2
I would appreciate any idea how to solve this, ideally as a SQL solution or maybe a function.
Thank you very much!

The difference between two dates is a number, where 1 = 1 day. Multiply by 24 to get hours.
Use the LAG, as stated above, to compare the date prior to the current date.
create table T(TID, EVENT, TDATE) as select
1, 'start', TO_DATE('03/05/2012 13:00:00', 'dd/mm/yyyy hh24:mi:ss') from DUAL union all select
1, 'Stop', TO_DATE('04/05/2012 15:00:00', 'dd/mm/yyyy hh24:mi:ss') from DUAL union all select
1, 'start', TO_DATE('07/05/2012 09:00:00', 'dd/mm/yyyy hh24:mi:ss') from DUAL union all select
1, 'Stop', TO_DATE('09/05/2012 10:00:00', 'dd/mm/yyyy hh24:mi:ss') from DUAL union all select
2, 'start', TO_DATE('06/08/2012 08:00:00', 'dd/mm/yyyy hh24:mi:ss') from DUAL union all select
2, 'Stop', TO_DATE('07/08/2012 10:00:00', 'dd/mm/yyyy hh24:mi:ss') from DUAL;
select tid, round(sum(hours)) hours from (
select case
when EVENT = 'Stop' then 24*(TDATE - LAG(TDATE) over(partition by TID order by TDATE))
else 0 end hours,
TID from T
)
group by tid;
TID HOURS

calculate the time difference between several lines
Hello
I have a table as below:
create table select TEST_CASETBL (ID, CASE_NUM, CASE_STATUS, CASE_SUB_STATUS, LAST_UPD_DTTM)
112, 123-456', 'open', 'Work', TO_DATE (11 March 2015 13:00 ',' dd/mm/yyyy hh24:mi:ss') of the DUAL union all select

315, 123-456', 'open', 'Work', TO_DATE (September 15, 2015 10:00 ',' dd/mm/yyyy hh24:mi:ss') of the DUAL union all select

651, 123-456', 'open', 'Work', TO_DATE (August 20, 2015 10:00 ',' dd/mm/yyyy hh24:mi:ss') from DUAL;
I would like to calculate the duration total (days ideally) to CASE_SUB_STATUS, so have a set of lines:
CASE_NUM of work waiting on admin waiting on customer
-------------------------------------------------------------------------------------------------------------------------------------------------------
123-456 70days 6 hours
Here is the explanation of the pattern:
ex: for everyday business computing (timestamp timestamp of ID:651 - ID:219) +(timestamp of ID:315-timestamp of ID:114) + (ID:112 stamp - current_time) = 11 days + 21 days 22hrs 23hrs 36 days 9 hours
still waiting on admin
(ID:219 timestamp - timestamp of ID:315) + (ID:113 timestamp - timestamp of ID:112)
still waiting on the client
(ID:114 timestamp - timestamp of ID:113)
I would appreciate any idea how to solve this, ideally as an SQL

How do the time difference between two dates?
Hi all
I use this query to get the time difference between two dates.
Select to_timestamp ('2012-10-03 12:00 ',' YYYY-MM-DD hh)-to_timestamp ('2012-10-03 11:00 ',' YYYY-MM-DD hh) as double diff;
but do not get the correct result.

How to set the time difference between each data when using keithley 2400 scanning
Hello friends,
I use scanning Keithley vi the extent of SCANNING and acquire vi. I want to measure the voltage for each step and a pause between each two data, so I need a delay between each I step.
I'm a starter to use Labview, thank you very much for your answers.
Perry
As Dennis says, if you use the built-in scan function, you will need to consult the manual. See Section 10-16 (this is page 10 of article 16, only paragraphs not but 10, 16) for the manual Keithley 2400.
The Keithley 24xx series has a speed of measurement in units called PLC (Power Line Cycles). The default speed is 1PLC, which means a measure is taken with each cycle of line 1 power supply or 1/60th of a second (16.67ms). 24XX can range from 0.01 PLC (all 0.16ms) 10 PLC (all 166.6ms). The faster you measure, the less accuracy you get.
To programmatically set this value, the command is
ENSe:CURRent:NPLCycles
ENSe:VOLTage:NPLCycles
Depending on what you are sensing and where
is the number of controllers from 0.01 to 10. Another factor that will determine the time between data points is the cycle SDM. These are more complicated, look at your Keithley manual for more information. Look at article 6 and article 11 for more information.
Note:
PLC times are based on a cycle of 60 Hz US.

Hallo,
I use the following system:
- OR PXI-1044 with controller NI PXI-8109
- OR PXI-2564 switch module to turn on the monitor of my test device
- Data acquisition multifunction NI PXI-6259 to measure the signal that responded to the questionnaire jump
The two cards are the same - PXI trigger bus. For both, PXI-2564 and PXI-6259 I use DAQmx to set the reading and writing of the channels.
Now, I want to measure the time between the digital output, my unit turns and the analog input, which measures the response of my system.
I can't do work by myself, please help me!
I thank Ludwig.
Hi Ludwig,.
If you can't give us any VI we have difficulties with to help you.
Because I Donat knowledge how your program is mounted it is not easy to know where you should enter signals.

var repeat: Number = 1;yahooTime.start ();
yahooTime.addEventListener (TimerEvent.TIMER, displayCall);
function displayCall(event:TimerEvent):void

}your first trace() statement is almost certainly not what you want.
dtDate2 is 08/08/2009
and it's probably not what you want. Flash months are zero-based. That is to say, January corresponding to month 0 and December is the month 11.

"There is a time difference between the client and the server"
Unit 4.0.3
Everything worked very well, and all of a sudden, I'm not able to connect to the server unit using any domain account. When I enter the domain/name username/password, I get this error message:
************************************************
The system is unable to log on due to the following error:
There is a time difference between the client and the server.
Try again or contact your system administrator.
**************************************************
I can use the same domain account (unityinstall) and the journal in other machines. I can connect the machine to the unit using a local account. There is no time difference between the DC server and unity.
Need help,
Thank you

What is the main difference between Excel Addin and SmartView?
Hi all
What is the difference between Excel Addin and SmartView in Hyperion 11.1.2?
Thanks in advance
RSG
Published by: RSG on March 29, 2011 05:42If you want the main difference between the Excel add-in and smartview I'd say it's just they way it connects and retrieves the data. the add-in uses the grid api and tcpip and smartview uses java on the web. There are a ton of differences between the supplement and smartview, but as the versions come thay are close. Here are a few others can add to the list:
---------------------------------------------------------------------Add-in------------------------------smartview
works on several office products - no - yes
Can connect to
Essbase-----------------------------------------------------------No---------------------------------------Yes
HFM----------------------------------------------------------------No---------------------------------------Yes
Planning----------------------------------------------------------No---------------------------------------Yes
Can view members and aliases at once - Yes - No
Leaf specific options - Yes - No
Great shims formatting - Yes - sometimes -

How to read the voltage difference between the 2 pins of a RS232?
Hi, I'm new in this field and I'm having a problem in the acquisition of data from a RS232 port. In fact, I don't know if it is possible to do.
What I would do, is to read the voltage difference between the two pins of the port. It's because I want to measure the temperature (and save the data) in a very simple way. I have 6 thermocouples and I thought weld at the different pins of the RS232 interface and acquire analog signals in mV with the computer. Then, I would use a thermometer to calibrate the values.
Is it possible to do? How? I searched a lot but I can't find any tutorial or similar to this example...
No, it is not possible to do it with the serial port. The port is not an A/D converter. A simple RS-232 tutorial will tell you that the port is binary in nature.

Hi, someone can describe the main differences between these 2 lenovo GST. I choose between these two. Any advice would be beneficial. Kenneth
The t400 you watch is CCFL and the T500 is LED backlite, I noticed the LED screens are a little more usable and need to improve your battery a little.
2 additional questions:
1 read the info product how can I determine who has the ccfl compared to the led... I tried but have not found.
2. I also have a t400 6474-wnp is similar to 2765 - 32 g?
