• Cumulative number of separate

  Hello
  
  I have a question about the analytical functions. What I'm trying to achieve is: calculate the cumulative number of separate.
  
  For example, to 20091001 I need to count the distinct subscribers on this date. I have need to also consider 20091001 to 20091002. 20091003 I must consider 20091001 to 20091002. You got the point.
  
  Below, I have attached the input data and also my goal. I tried some of the windowing functions with no luck.

• a kind of cumulative number

  Hello

  I'm fighting to get a sort of running a table number, but I can't do it without a view... But maybe there is a better way to do it.

  The table is:

  ID     CAT_ID     NAME     FLAG
  1     2     AAA          null
  2     2     BBB          A
  3     2     CCC          A
  4     2     DDD          null
  5     4     AAA          null
  6     2     EEE          B
  7     2     FFF          A
  

  And I need to count the flag 'A' for CAT_ID = 2, the result should be like:

  ID     CAT_ID     NAME     FLAG     COUNT
  1     2     AAA          null          0
  2     2     BBB          A          1
  3     2     CCC          A          2
  4     2     DDD          null          2
  6     2     EEE          B          2
  7     2     FFF          A          3
  

  Please notify.

• How to get essbase excel add in the display of the total cumulative number?

  Version 11.1.2.1
  
  When I connect firstly in my ASO application via the excel add-in, the first thing I see is a null value. My first dimension/column is 'period '. Period is marked as a dynamic calc and label only.
  
  When I drill down in the period I see obviously all rollup values. How can I get the excel to display the full cumulation (instead of having to drill down) when I connect firstly because I like to keep my options as ' delete missing values / zeros "checked.
  
  I see in Sample.Basic is 105522. I want something like that. I tried reloading the numbers and changed the properties without result.
  
  What is the logic behind this?

  If "Period" is marked as 'Label only' it will take the value of her first child, if the first child has a value of #Missing, then "Period" also will display a value of #Missing. If you want to 'Period' to show all the periods (as Sample.Basic does) then you need to take off the "Label" label only

• capture multiple and reading images

  Hi all

  I use a Guppy F031 Pro camera equipped with trigger mode in bulk.  Now I can leave the exposure of the device twice in the series after an external trigger (my previous post).  But I don't know where are the stored images and how to read the two outside pictures and store them in the hard disk.

  When I use IMAQdx get image vi to capture image and set as number mode with 2 buffer pads.

  Does this mean that I assigned two location in RAM for my image?  If so, how can I find their location?

  

  Best,

  Wen

  "When I use IMAQdx get image vi to capture image and set as number mode with 2 buffer pads.

  -To my knowledge, it is false.

  Buffer allocation:

  -There are two types of internal buffers and buffer of the user you want to set up and use.

  -internal buffer is that you can configure using IMAQdx configure acquisition and giving the required number of buffers you want to allocate.

  -the user buffer is a condigure you or create using IMAdx create and giving them different middle names, creating several buffers. (You must remove the user buffers when finished processing using IMAQdx has, otherwise it will fill the RAM memory.

  Number of buffer:

  -A number of buffer is a zero-based index that represents the cumulative number transferred image. For example, during an acquisition continues with three internal buffers, the number of buffers is updated as follows: 0, 1, 2, 3, 4, 5 and so on. Buffer 0 and 3 numbers correspond to the same internal buffer in the ring of the buffer. (From NI IMAQdx manual)

  -Which means you will need to give different buffers number each time adding 1 whenever you receive an image. and not a constant of 2.

  For your question:

  -Configure the acquisition with more than two buffers, start the acquisition.

  -Give the number of buffers to 0 and increment after successful image and send it to IMAQdx get image.

  -For each image, your user buffer is even currently, which means that it will overwrite the same. If you want them to be different, you can create several and use also.

• Spectral histogram of adc output

  G ' Day all the

  I have a LabVIEW task that I'm confident should be dealt with before (several times). However, not for the life of find me a solution documented. It's displaying a range of possibilities of an ADC on a histogram channel (no, not the statistical flavor - the spectral version of science).

  I have a 8 k ADC front-end DAQ loop which (for reasons of this example) gives me the amplitude of incoming impulse (value between 0 and 8191). In this loop, I would a 'live' spectrum in real-time of the cumulative number of hits by way of the ADC.

  I can think of ways using an 8 k array and incrementing the bins manually but how to get the data in the table persistent in the loop... and actually display.

  If I have to invent my own wheel to solve this problem while it is OK, but I'm sure that like most of my brothers of coding, I'd rather use someone else

  See you soon
  Steve

  Look at this example of a histogram. Which is similar to what you need?

• Rate counters/timers

  Hello

  I use the entrance of counter/timer on a map of 6040E for counting of events.

  I use CTR0 and have specified the clock 20 MHz as my source and connected my event at the door (PFI9). I has a finite number of impulses and I am configuration of the buffer using the DAmx Timing (example of clock) vi.

  My question concerns the entry of 'rate. ' Counter source is positioned at 20 MHz is not the rate? Can anyone advise as to how to choose a reasonable value and what effect it has.

  I usually use the rate for analog I/o buffers in order to fix the rate of buffer - I can't quite see its use in this case.

  Thank you

  I forgot to go to the part of rates, for counting of events, the rate is how many times buffering you your edge counter value.

  IE I count photons a PMT, I would like to see the cumulative number every 1ms so I plug the source on the PMT and run continious at 1 kHz, every second, I read 1000pts and plot.  I think that this is how the rate.  For measurements, the clock is implied, there is no price since the edges of ascnchronous determines the time to write to the buffer.

• Help explain the flow meter VI

  After a lot of tinkering, I seem to have developed an effective VI for use with a type/pelton turbine flowmeter. The flow meter outputs a stream of pulses which

  can count on the counter of my 6501 line. Unfortunately this eureka moment happened somewhat by chance, and I'm hoping someone

  could be kind enough to explain step by step or in terms very simple for beginners (me) works of VI, thank you.

  Kind regards

  GER,

  Welcome to the Forums and LabVIEW.

  If you don't the have already made, please work through the tutorials online to get started with LabVIEW. The answers to some of the questions you may have are probably there.

  A brief description of your VI:

  1. the overall structure is a loop For. It works for the number of iterations that is connected to the Terminal in your case 5 N.

  2. the calendar of the loop is determined by the longest time required for any part of the code inside the loop execution. On the first iteration, the DAQ Assistant configures the counter and starts measurement. On all subsequent iterations, he reads everything simply an indictment. On these iterations, the 25 les 25 ms ms expect will dominate. This VI runs approximately 40 iterations per second (for 5 iterations).

  This means that the program will take place on 5 * 25 ms = 0.125 sec and then stops. If you run for more 1/8 of a second to help run it continuously button, STOP. Which is intended for certain types of troubleshooting only.

  3. the table of waveform and the flow rate meter only shows the last value of the five iterations. (This suggests also that you use run continuously)

  4. the registers at offset in this VI nothing do. The upper shift register calculates the cumulative number of the flow meter, but the result is never used. The underpass registry has nothing connected to the Terminal inside the loop on the left. It could be replaced by a terminal.

  Suggestions:

  1. in order to avoid using run continuously, replace the loop with a while for loop. Add a stop button on the front panel and connect it to the stop it real terminal in the loop. Move the graphic terminals of waveform and flow inside the loop.

  2 check your pulse to the algorithm of flow rate. The time for the count interval must be considered.  For example if the meter registers 25 pulse in 25 Member States, which represents 1 000 pulses per second. This isn't which will show your VI.

  3. see examples of code that uses counters.

• Monitoring of VPN - running Total

  Hello

  I was wondering what is the meaning of the Total cumulative number means?  I guess it's just the total amount of connection which took place up to this point and does not affect the total number of allowed simultaneous connections?

  Thank you.

  Hi Max,.

  The cumulative is simply a number of Ipsec firewall connections recorded since is online.  This has no effect on the number of counterparts Ipsec or VPN simultaneous connections the ASA can manage.  Cumulative are just statistical database on all of your SSL/VPN, etc... saved connections.

  These statistics can be eliminated by clear statistics of vpn-sessiondb in global configuration, or mode when the firewall is reloading.

• How oracle decide whetehr to use the index or full analysis (statistics)

  Hi guys,.
  
  Let's say I have an index on a column.
  Tables and index statistics were collected. (without the histograms).
  
  Let's say I have run a select * from table where a = 5;
  Oracle will perform a complete analysis.
  But what statistics, it will be able to know indeed the greater part of the column = 5? (histograms do not used)
  
  After analysis, we get the following:
  Statistical table:
  (NUM_ROWS)
  (BLOCKS)
  (EMPTY_BLOCKS)
  (AVG_SPACE)
  (CHAIN_COUNT)
  (AVG_ROW_LEN)
  
  Index statistics:
  (BLEVEL)
  (LEAF_BLOCKS)
  (DISTINCT_KEYS)
  (AVG_LEAF_BLOCKS_PER_KEY)
  (AVG_DATA_BLOCKS_PER_KEY)
  (CLUSTERING_FACTOR)
  
  Thank you
  
  
  
  
  
  Index of column (A)
  ======

  I have prepared a few explanations and did not notice that the topic has been marked as answer.

  My sentence is not quite true.

  A column "without histograms' means that the column has only a bucket.

  More correct: even without the histogram there are data in dba_tab_histograms which can be considered a bucket for the whole column. In fact, these data are extracted from hist_head$, not from $ histgrm as usual buckets.
  Technically there are no buckets without combined histograms.

  Let's create a table with the asymmetric data distribution.

  SQL> create table t as
    2  select least(rownum,3) as val, '*' as pad
    3    from dual
    4  connect by level <= 1000000;
  
  Table created
  
  SQL> create index idx on t(val);
  
  Index created
  
  SQL> select val, count(*)
    2    from t
    3   group by val;
  
         VAL   COUNT(*)
  ---------- ----------
           1          1
           2          1
           3     999998
  

  So, we have table with the very uneven distribution of the data.
  We collect statistics without histograms.

  SQL> exec dbms_stats.gather_table_stats( user, 'T', estimate_percent => 100, method_opt => 'for all columns size 1', cascade => true);
  
  PL/SQL procedure successfully completed
  
  SQL> select blocks, num_rows  from dba_tab_statistics
    2   where table_name = 'T';
  
      BLOCKS   NUM_ROWS
  ---------- ----------
        3106    1000000
  
  SQL> select blevel, leaf_blocks, clustering_factor
    2    from dba_ind_statistics t
    3   where table_name = 'T'
    4     and index_name = 'IDX';
  
      BLEVEL LEAF_BLOCKS CLUSTERING_FACTOR
  ---------- ----------- -----------------
           2        4017              3107
  
  SQL> select column_name,
    2         num_distinct,
    3         density,
    4         num_nulls,
    5         low_value,
    6         high_value
    7    from dba_tab_col_statistics
    8   where table_name = 'T'
    9     and column_name = 'VAL';
  
  COLUMN_NAME  NUM_DISTINCT    DENSITY  NUM_NULLS      LOW_VALUE      HIGH_VALUE
  ------------ ------------ ---------- ---------- -------------- ---------------
  VAL                     3 0,33333333          0           C102            C104
  

  Therefore, Oracle suggests that the values between 1 and 3 (raw C102 C104) are distributed uniform and the density of the distribution is 0.33.
  We will try to explain the plan

  FTS here costs 300 and Index Range Scan here costs 2377.
  I disabled cpu cost, so the selectivity does not affect the cost of FTS.
  cost of the Index Range Scan is calculated as
  blevel + (leaf_blocks * selectivity + clustering_factor * selecivity) = 2 + (4017 * 0.33333 + 3107 * 0.33333) = 2377.
  Oracle believes that he must read 2 blocks root/branch index, 1339 the index leaf blocks and 1036 blocks in the table.
  Pay attention that the selectivity is the main component of the cost of the Index Range Scan.

  We will try to collect histograms:

  ENDPOINT_VALUE is the value of the column (in number for any type of data) and ENDPOINT_NUMBER is the cumulative number of lines.
  Number of lines for any ENDPOINT_VALUE = ENDPOINT_NUMBER for this ENDPOINT_VALUE - ENDPOINT_NUMBER to the previous ENDPOINT_VALUE.

• SQL query problem finding difference in documents

  Hi all
  I use oracle 10g. I need emergency aid to find the difference in documents based on the date:
  
  I have sales of the table as below:
  
  seller SALES_COUNT DATE
  JOHN 20 04/01/2012
  DENNY 15 04/01/2012
  JOHN 30 04/02/2012
  DENNY 30 04/02/2012
  JOHN 45 04/03/2012
  DENNY 50 04/03/2012
  
  
  SALES_COUNT is up to man including the date of sale. Its similar cumulative number. John has total sales of 01/04/2012 to 03/04/2012 is 50 and same case for Denny. This SALES_COUNT will keep increasing with dates as sales continue to add in the table for each salesperson.
  But I want to have seprate for each seller counties.
  for example: JOHN SALES_COUNT 04/02/2012 is 30-20 = 10
  JOHN SALES_COUNT 03/04/2012 is 45-30 = 15
  DENNY SALES_COUNT, 02/04/2012 is 30-15 = 15
  JOHN SALES_COUNT 03/04/2012 is 50-30 = 20
  
  Please help me with this scenario and let me know if you need clarification. I would much appreciate your help.
  
  Thank you.

  This gives you what you want?

• Query to select values that correspond to several beaches

  Hello
  
  Oracle 10g.
  
  I have a POINTS table (ID INTEGER, CLASS VARCHAR2 (15), CUMULATIVE NUMBER (2.1),...).
  
  In my application (APEX), I show a list of classes of point, order by date.
  

  SELECT CLASS FROM POINTS ORDER BY CUMUL;

  Then the user can choose a range of classes point (CUMULATION is not indicated in the request, it's just for example):
  

  CUMUL     CLASS 
  12.2     31458     <-  
  13.4     5S84     <-     range 1  
  13.6     78PPH     <-  
  15.0     3R594     <-  
  15.1     ZB452  
  15.5     54IO  
  17.6     21GFD  
  19.2     A54VV     <-  
  19.9     IC112     <-     range 2  
  20.8     158RC9     <-  
  21.3     G4G5  
  23.0     V22     <-     range 3

  For each range, I only store the first classes and he would give the last selected by a user, in a table USER_SELECTION (ID, ID_USER, FROM_CLASS, TO_CLASS), so using the example above:
  

  ID     ID_USER          FROM_CLASS     TO_CLASS  
  1     12          31458          3R594  
  2     12          A54VV          158RC9  
  3     12          V22          V22 
  ...     ...          ...          ...

  The problem is that in a query, I need to return all items selected by a user, and I don't really know how to get there without too much work...:
  
  SELECT *.
  POINTS
  WHEN USER_ID = 12
  AND IN THE CLASS (*? *);
  
  Any help would be appreciated.
  
  Yann.

  It is clear exactly what data are held in which tables etc but maybe something like this...

  select user_selection.id, points.*
  from points, user_selection
  where user_selection.user_id = 12
  and   points.cumul between
        (select cumul from points where class = user_selection.class1)
        and
        (select cumul from points where class = user_selection.class2)
  order by user_select.id, points.cumul
  

• HFM - error illegal assignment rules editor

  HFM version 9.3.1.0.0 rules editor
  
  I wrote rules to get a cumulative number from January to November.
  
  I managed to do work until September, but when I get to October he gives me an error when I consolidate illegal assignment: "OCT."
  
  Why Oct would be illegal? In the code Oct (see below) appears blue, but all other months appear in black. Does anyone know what's not here?
  
  
  Here is the code:
  
  If vDollar_Overrides_8 = 0 and vDollar_Overrides_9 = 0 Then
  ("Sep = Aug & ') + ((A #"& sAcct &".)) C1 #TOTC1. C2 #[no]. Top of P #Aug.I #[ICP]. C4 #[no]. V # < entity Curr Total > * "& EOM_9 &"-() "& _" ""
  "A #" & sAcct & ".." C1 #TOTC1. C2 #[no]. Top of P #Aug.I #[ICP]. "C4 #[no].
  On the other
  Ms = 0
  End if
  
  If vDollar_Overrides_9 = 0 and vDollar_Overrides_10 = 0 Then
  Mistake here = > ("Oct = Ms & ') + ((A #"& sAcct &".)) C1 #TOTC1. C2 #[no]. Top of P #Sep.I #[ICP]. C4 #[no]. V # < entity Curr Total > * "& EOM_10 &"-() "& _" ""
  "A #" & sAcct & ".." C1 #TOTC1. C2 #[no]. Top of P #Sep.I #[ICP]. "C4 #[no].
  On the other
  Oct = 0
  End if
  
  If vDollar_Overrides_10 = 0 and vDollar_Overrides_11 = 0 Then
  ("Nov = oct & ') + ((A #"& sAcct &".)) C1 #TOTC1. C2 #[no]. Top of P #oct. I #[ICP]. C4 #[no]. V # < entity Curr Total > * "& EOM_11 &"-() "& _" ""
  "A #" & sAcct & ".." C1 #TOTC1. C2 #[no]. Top of P #oct. I #[ICP]. "C4 #[no].
  On the other
  Nov = 0
  End if
  
  
  HS.exp "A #" & sAcct & ".." C2 #TAX_CTA_Chg_PYDec.I #[ICP None]. "C4 # = [none] (" ' & Nov & "").

  Odd - did the same thing on my HFM rules editor. It's as if the editor uses "Oct" as a system variable or a command. Briefly, I looked at the Oracle's Web site for documentation on the rules editor, but found nothing. You can use "strOct" or a Variant to work around the problem.
