Need a Query to Get Execution time of each query in Proc if its running
I am looking for query which give total execution time of individual query running currently ?
we have queries but it will give cumulative time from the start date,
for example - if stored proc has 10 queries , if each query taking 10 seconds it should show me 10 secoond if its running, not from when stored proc execution started , if you have any query please let me know
only for running queries ,
Is this the logic you're after?
DECLARE @timeStamp DATETIME2 = CURRENT_TIMESTAMP, @lapTimeStamp DATETIME2, @x INT = 0
SET @lapTimeStamp = CURRENT_TIMESTAMP
WHILE @x < 10000
BEGIN
SET @x = @x + 1
END
PRINT CAST(DATEDIFF(MS,@TIMESTAMP,CURRENT_TIMESTAMP) AS VARCHAR) + ' milliseconds have elapsed since the begining of the proc. ' + CAST(DATEDIFF(MS,@lapTimeStamp,CURRENT_TIMESTAMP) AS VARCHAR) + ' have elapsed since the last batch'
SET @lapTimeStamp = CURRENT_TIMESTAMP
SET @x = 0
WHILE @x < 10000
BEGIN
SET @x = @x + 1
END
PRINT CAST(DATEDIFF(MS,@TIMESTAMP,CURRENT_TIMESTAMP) AS VARCHAR) + ' milliseconds have elapsed since the begining of the proc. ' + CAST(DATEDIFF(MS,@lapTimeStamp,CURRENT_TIMESTAMP) AS VARCHAR) + ' have elapsed since the last batch'
SET @lapTimeStamp = CURRENT_TIMESTAMP

Need to get travel time of each echo
Hi,
I want to calculate the travel time of an echo.
The data I have, is a triggered pulse and 4 echoes in a single graph at different time intervals.
Now, I want to calculate the travel time of each echo from triggered pulse start.
Method I want to use,
1. Calculate first trigger point.
2. Get the end of waveform and gate the data.
3. Again repeat step 1 and 2 , to get first trigger point.
Is there any way to calculate the point where waveform ends or is almost constant?
Or, is there any other method to calculate travel times.
I am new to LabVIEW.Please help.
Thanks, AmitAnswers to your questions will depend on how you have your acquisition set up.
I general, I would expect that you'd set up the system to wait for a loud noise and then take some finite amount of samples (e,g, 100k samples at 10kHz) that will be sure to capture the echos. In this scenario you will alway get the same number of samples.
You can get the amplitudes of the data by using "get waveform components.vi" or "convert from dynamic data" and then use "threshold 1D array" to find the rising edge of the echo peaks. -
How to get execution time for a view inside procedure ?
Hi,
I want execution time for all the views in my database. I tried "execute immediate" but it does not seem to work.
It is not waiting to complete the execution of view to go to next step.
If I am executing the same statement in sqlplus, it is displaying correct time.
Here is my code:
Begin
output_file := UTL_FILE.FOpen ('RECORDING',v_FileName, 'W', 32767);
Open viewcur;
Loop
Fetch viewcur into v_view_name;
Exit when viewcur%notfound;
SELECT to_char(systimestamp,'DD-MON-YYYY HH24:MI:SS.FF') into v_start_time from dual;
v_stmt := 'Select * from ' ||v_view_name ;
Execute Immediate v_stmt;
SELECT to_char(systimestamp,'DD-MON-YYYY HH24:MI:SS.FF') into v_end_time from dual;
v_record_str := v_start_time||','||v_view_name||','||v_end_time;
UTL_FILE.PUT_LINE(output_file, v_record_str);

To Check the execution time for each transaction.
Abapers,
How to find out the process time for each transaction eg.order entry,shippng,billing, etc in SAP.
TIA,

By default you can see the execution time at right side corner of sap session.
You can use SE30 to get in to more details like database time , abap time etc...
Hope it helps...

HT204053 Can two people use one account and get face time to each other?
I'm getting a new ipad and I'll be handing over my ipad 3 to my Hubby. I was wondering if we could both share different IDs in the same account and be able to face time each other from my account.

You don't have to create another account - I facetime and imessage with my wife's ipad all the time using one apple id. All you do is on one device check mark one email address in " send and receive " area and on other ipad another adress. So I do that from ***@hotmail to ***@icloud. BTW imessage and facetime have nothing to do with icloud or itunes and to have different id's for icloud would be my recommendation as well. -
I setup two iphones on "Find My Iphone App" Using the same apple id on each phone. Now the app finds only the phone I setup first. Do I need to use two different apple ids? If your answer is yes then how do I errase the setup in the second phone and assign a new id?
As TJBUSMC1973 states, and as I said earlier, the Find My iPhone app has nothing to do with your use of Find My iPhone. The app is just used if necessary to locate another iOS device from that particular iOS device. To see if both of your devices are being located in Find My iPhone, log into www.icloud.com and select Find My iPhone. Both of the devices should appear. If they do not, then go into whichever of the devices does not appear and make sure that Find My iPhone is activated. It has to be activated through iCloud, and for both to show on the same map, they both have to have the same iCloud ID.

How to get the execution time of a query
Hi,
Environment: 10.2.0.4.0
Just wondering how I can get the query execution time? I am not interested in the query output nor do I want the statistics, just the execution time?
Any suggestions will be appreciated
Thanks in advance
rogers42If you're using SQL*Plus
SQL> set autotrace traceonly
SQL> set timing on
SQL> <<your query here>>SQL*Plus will fetch all the data and then report the query plan, execution statistics, and elapsed time. It will not display the actual data.
SET TIMING ON alone tells SQL*Plus to display the execution time of each SQL statement-- the problem is that it also displays all the data which can skew the results because you're including the time required by SQL*Plus to pipe a bunch of data to the screen.

Thanks.Welcome to the forum!!
Please read {message:id=9360002} from the FAQ to know the list of details (WHAT and HOW) you need to specify when asking a question.
I primarily hate 3 things in your code
1. The way you have used BULK update which is totally unnecessary
2. COMMIT inside LOOP
3. The use of WHEN OTHERS exception.
Your code can be simplified like this
create or replace procedure my_proc
is
v_start_time timestamp;
v_end_time timestamp;
v_rowcnt integer;
begin
for c1 in (
select rownum tab_no
, tablename
, type
from table_list
loop
sql_string := q'[
merge into #tablename# a
using (
select id, dt
from emp_base
) b
on (
a.empkey = b.empkey
when matched then
update set a.id = b.id;
sql_string := replace(sql_string, '#tablename#', c1.tablename);
v_start_time := systimestamp;
execute immediate sql_string;
v_end_time := systimestamp;
v_rowcnt := sql%rowcount;
insert into exec_time
values
c1.tab_no || ' ' || c1.tablename
, v_start_time
, v_end_time
, v_end_time - v_start_time
, v_rowcnt
end loop;
commit;
end; In the INSERT statement on the table EXEC_TIME try to include the column list.

Tool for measuring execution time?
Hi,
i'm trying to measure the time of some determined methods in my app.
I've tried System.currentMillis(), but i don't get the accuracy i need (System.nanoTime() - from 1.5.0 sdk won't help me neihter).
Does anyone know a simple java tool that i can use to do this ???
I thought about optimized (borland), but i just don't have it :-( also i don't know if it ease to use (and i need this measuring as soon as possible).
Thanks for any sugestion,
ltcmelo<<In Windows at least the resolution of System.currentTimeMillis() seems to be 10ms.
If the operation that takes 9 ms is called a thousand times, and the one that takes 5 ms is called 20
million times, and the one that takes 1 �s is called 200 million times, all will be fast to measure,
all will come in at zero ms by currentTimeMillis(). It would be useful to know the respective execution times of each method.>>
This is not correct. Windows does have 10 ms. granularity, however if you average many measurements this limitation disappears.
For example let's say that a particular method takes 5 ms. on average and we take 10 measurements. You claim that the 10 measurements will all be 0, whereas the actual measurements will either be 0 or 10 depending on how close the clock was to ticking when currentTimeMillis() was called. For example the 10 measurements might look like 0, 0, 10, 0, 10, 0, 0, 10, 10, 0. If you take the average of these numbers you get quite good accuracy (i.e. 50/10=5 ms. the actual time we said the method took). In principle the average should even get you sub-ms. accuracy.
Try it with jamon (http://www.jamonapi.com). JAMon calculates averages and so gets around the windows limitation. If you are coding a web app then jamon has a report page that displays all the results (hits, average time, totals time, min time, max time, ...). If not then you can get the raw data and display it as you like.
One question for the original poster. Why do you think you need sub-millisecond timings? If you are coding a business app IO tends to be the bottleneck and much greater than sub-millisecond.

Evaluate the total execution time
Hi,
I need to find the total execution time taken upon executing a function module. I tried to output the system time in the start of the FM and at the end of the FM. But the time taken in execution in the DEV system could be lessthan 1 sec, which is not visible to evaluate.
Any one with an idea, please help.
Regards,
Satish KantetiHi,
You can use like below

GET RUN TIME FIELD T.
WRITE: / 'Begin Runtime', T.
*Call FM
GET RUN TIME FIELD T.
WRITE: / 'End Runtime', T.

CVI XML Functions Execution Times Increase When Looped
I have written multiple functions using CVI that read XML files. I have confirmed in the Resource Tracking utility that i have cleaned up all of my lists, elements, documents, etc. I have found that when I loop any of the functions I have created, the execution times increase. The increase is small but it is noticable and does effect my execution.
Are there any other sources of memory that I need to deallocate? It seems that there is a memory leak somewhere but I am unable to see where this increase is located.
I am currently running LabWIndows/CVI 2009 on Windows 2008 Server. I have looped my functions using TestStand 4.2.1. Any help would be appreciated!
Thanks in advance,
Kyle
Solved!
Go to Solution.HI Daniel,
Thanks for the quick response.
It is indeed slow down in execution speed when we loop. When looped, the XML reader is overwriting variables, not adding to an array. Our application is structured differently than my test case. We run a CVI function from TestStand that contains a series of commands, which contains the XML reading. The XML looping is really done in CVI. I used TestStand in my test case just to get execution times. Our psuedocode for the CVI function is as followed:
For loop (looping over values, like amplitude or frequency)
Reading the XML
Applying the data from the XML to set up some instrument(s)
Do something...
End loop
I can confirm that the instrument set up is not the cause of the slow down. We have written the same XML reading in C# and applied the values to the instrument setup and do not experience the slow down.
I tested with On-The-Fly Reporting enabled and the execution time continued to slow down.
I hope that answers all of your questions!
Thanks,

Why the execution time increases with a while loop, but not with "Run continuously" ?
Hi all,
I have a serious time problem that I don't know how to solve because I don't know exactly where it comes from.
I command two RF switches via a DAQ card (NI USB-6008). Only one position at the same time can be selected on each switch. Basically, the VI created for this functionnality (by a co-worker) resets all the DAQ outputs, and then activates the desired ones. It has three inputs, two simp0le string controls, and an array of cluster, which contains the list of all the outputs and some informations to know what is connected (specific to my application).
I use this VI in a complex application, and I get some problems with the execution time, which increased each time I callled the VI, so I made a test VI (TimeTesting.vi) to figure out where the problem came from. In this special VI I record the execution time in a csv file to analyse then with excel.
After several tests, I found that if I run this test VI with the while loop, the execution time increases at each cycle, but if I remove the while loop and use the "Run continuously" funtionnality, the execution time remains the same. In my top level application I have while loops and events, and so the execution time increases too.
Could someone explain me why the execution time increases, and how can I avoid that? I attached my test VI and the necessary subVIs, as well as a picture of a graph which shows the execution time with a while loop and with the "run continuously".
Thanks a lot for your help!

Thank you very much for your help! I added the "Clear task" vi and now it works properly.
If you are still using the RUn Continuously you should stop. That is meant strictly for debugging. In fact, I can't even tell you the last time I ever used it. If you want your code to repeat you should use loops and control the behavior of the code.

hai guys,
Im currently developing a code that run 24 hours 7 days a week. My problem is the execution time increases as days pass by. As im tracing down the execution time ,the 1st day i start the to run the program execution time is 0.04 second but after 3 day it increases to 4.5 seconds .
then i indually tracked down the subvi that causing problem and find out that the problem is on writing to ini file.
The subvi function is to REPLACE the data (20 data )in a file every 10 second*not accumulating data just replace the old data . I open file replace data and close file every itteration and as day pass the execution time for this subvi increases.
Can any one help me to get a solution for the problem as time is a very important factor in my programming. the execution time is limited for less that 10 second.
thanks
regards
kokulaAs David said, post the code.
Is there any reason why your are loggin to an .ini file? Does that mean you are using the LabVIEW config file functions?
I don't know if deallocating memory would help, or is even possible, without seeing your code. You either have a problem with resources continuously being created, but not being closed out. Or you have an ever growing array. This takes more memory over time, and slows down the code because LabVIEW has to move memory around to account for the ever larger array.
I bet if you let your program run long enough, it would eventually crash due to running out of memory.
By the way 47MB to 350 MB of memory consumption means the same thing as RAM usage increasing. -
How do i get a time bar??
Hi All,
I need to create a time bar....some kinda bar that progresses as time passes by. It should be kinda like the bar you see on windows media player at the bottom! What object do I use to achieve that??
To explain in detail..i have a log file wherein different events are stored sorted in time. I should read from the log and changes should take place on the screen based on the events in the log! For this I also need to have a time bar at the bottom which which kinda scrolls from one end to the other as I render the events in the log file from beginning to end!
Can someone suggest what object i need to use to get the time bar??
THanks!There's a good tutorial on progress bars in dialog windows in the Java Tutorial section - you can find it at java.sun.com. I bet you could modify their code a bit and have most of the work done for you!
cheers,
Andrew
