• How to count distinct exclusion of a value in the business layer?

  Hi all
  
  I have a column that has a lot of values. I need to do is a measure with aggregator separate count. But I shouldn't count 0 in the column. How can I do that. If I try to use any way to condition the aggregator option is disable. Help, please
  
  Thank you

  Look at this example:

  I did MDB table is DIRTY as:

  Count_Distinct_Prod_Id_Exclude_Prod_Id_144

  I'll count distinct PRODUCTS. PROD_ID, but exclude PROD_ID = 144 when counting.

  Make this measure like this:

  1. new column object/logic
  2. go in tab data type and click EDIT the table logic table source
  3. now, in the general tab add join of a table (in my case of PRODUCTS)
  4. go in the column mapping tab-> see the deleted column mapping

  5. in the new column (in my case Count_Distinct_Prod_Id_Exclude_Prod_Id_144) write similar code:
  CASE WHEN "orcl". » ». "" SH ". "PRODUCTS '." "' PROD_ID ' = 144 THEN ELSE NULL"orcl ". » ». "" SH ". "PRODUCTS '." "' PROD_ID ' END

  6. click OK and close the source logical table
  7. now, in the logical column window go to the tab of the aggregation and choose COUNT DISTINCT.

  8. move the Count_Distinct_Prod_Id_Exclude_Prod_Id_144 measure for presentation

  9 test answers (report cointains columns as follows)

  PROD_CATEGORY_ID
  Count_Distinct_Prod_Id_Exclude_Prod_Id_144

  And the result in the NQQuery.log is:

  Select T21473. PROD_CATEGORY_ID C1,
  Count (distinct from cases when T21473.) PROD_ID is 144, then NULL else T21473. End PROD_ID) C2
  Of
  PRODUCTS T21473
  Group of T21473. PROD_CATEGORY_ID
  order of c1

• Count distinct users registered

  Hello
  
  I have a table that contains the users and their hours of connection and disconnection. I need to know the maximum number of distinct users connected for a period of 15 minutes for each day. Periods of 15 minutes, start at 00:00 and ends at 23:45

                 , 'DD-Mon-YYYY'
                 )     AS end_dt
       ,     24 * 4          AS periods_per_day
       FROM     dual
  )
  ,     periods          AS
  (
       SELECT     start_dt + ((LEVEL - 1) / periods_per_day)     AS period_start
       ,     start_dt + ( LEVEL      / periods_per_day)     AS period_end
       FROM     parameters
       CONNECT BY     LEVEL <= (end_dt - start_dt) * periods_per_day
  )
  ,     got_cnt_per_period     AS
  (
       SELECT       p.period_start
       ,       COUNT (distinct user_id)     AS cnt
       ,       ROW_NUMBER () OVER ( PARTITION BY  TRUNC (period_start)
                                     ORDER BY      COUNT (*)   DESC
                             ,               period_start
                                  )         AS rnk
       FROM       periods     p
       JOIN       user_data     u  ON   p.period_start     <= u.logout_date
                         AND     p.period_end     >  u.login_date
       GROUP BY  p.period_start
  )
  SELECT       period_start
  ,       cnt
  FROM       got_cnt_per_period
  WHERE       rnk     = 1
  ORDER BY  period_start
  ;
  

  You will notice that it does not use the pivs table. Generate periods of time with a CONNECT BY query is likely to be more effective, and you don't have to worry about having enough rows in the table pivs.
  In this way avoids also all conversions between DATEs and strings (except for the entrance of the start_dt and end_dt parameters), which should take some time.

  If you are actually hardcode the parameters in the query, the abopve version will be easier to use and maintain, because each parameter only has to register once, in the first auxiliary request.

  The output includes the start time of the period who had the highest number on each day. If there are equal (as in this example of data, there were 3 periods December 1, which had a number of 2), then the specified period is that earlier that day. If you want to see all, replace ROW_NUMBER RANK by the last auxiliary request, got_cnt_per_peroid. Of course, you don't have to display the time if you do not want.

• OVERALL TOTAL incorrect (with COUNT DISTINCT)

  Hello
  
  I get incorrect results in a DISTINCT COUNT measure column GRAND TOTAL.
  
  I have 5 separate in Paris and 10 separate clients in New York, I want the grand total for the sum of the two, it is 15.
  But OBIEE calculates separate customers for all cities, so if there are customers in Paris and New York, the result is false.
  
  
  This is the result I get:
  
  City Number_Distinct_Customers
  ----------------------------------------------------------------------------
  Paris 5
  NEW YORK CITY 10
  GRAND TOTAL 12
  
  
  12 is the number of all separate clients.
  
  The correct GRANT TOTAL is expected to be 5 + 10 = 15
  
  
  
  Thank you
  Concerning

  I guess that COUNT(DISTINCT...) is regarded as the default aggregation in the Oracle replies.
  To come in this, change the State of aggregation of fx (formula column in the criteria of answers tab) to 'SUM '...

  Let me know if that solves your problem.

• Vs Count Distinct Count

  What is the difference between the meter and the meter separate in the advanced INTERFACE

  Operations-> all settings-> deployed-> Count?

  This metric is available in the advanced user interface and the custom user interface. Measures are not read in the Admin UI.

  Distinct count is the actual number of virtual machines deployed, while the County is # trend / forecasting of the deployed virtual machines. Usually, you will notice the separate account doesn't have a very clear dynamic threshold, but the County has a dynamic rise. Speaking of which, I would say probably a couple more VMs to meet forecasts of my lab... ha.

• Maximum, Count Distinct functions in the model.

  Hello
  
  I have a set of data that I tried to regroup for a report.
  I need in the report so that I have product code list in a column and Max (Product Code) in another column product code, product code Sub are strings and not numbers.
  
  
  Suppose that my data set has
  
  
  product code:-product-sub-code

  ABC | 1A
  ABC | 1 b
  ABC | 1 c
  def | 1 B

  I need to report
  
  ABC | 1A

  ..
  
  
  
  I gathered it and I tried to show the Max (product code) for the current group. But it gave me a number instead of text. I tried to select 'text' to the form field. But it is automatically change the number.
  
  
  Also, can you let me know how to write the number (code of separate by-product). I must also add that column.
  
  I can't add in SQL because there are tons of models on this data set. I have to do it in the model.
  
  Any help is greately appreciated.

  Try using this: -substitute your domain under product code name

  Thank you

• I counted 99 update Windows XP how to check your computer to see if you need updates after that you disabled them to inform you?

  I counted 99 updates to Windows XP, Explorer 10 ea.Netframework3.0 Service Pack 13 c., Net framework as MS Framework 2.0 1.1 has 15 updates. All this can I? I think that I have disabled the new notifications on updates, how can I check to see if I am up to date?

  You must know if you turned off to THE or not probably.

  Once you turn on to THE, then go and manually check the updates are applicable to your computer, including optional updates.

  In regards to the framework, if a program requires the Framework will advise you.

  Hello
  
  It is a simplified version of my request.
  I'm doing 4 things here,
  1. the County A.M_ID
  2 County has separate .M_ID, is where I have a problem.
  3 and 4. It is just the sum of 2 diff columns.
  
  Note that the dates for the County and the amt are different and I can't hard-code the.
  Can someone help me step of distinct count?
  This query runs also a bit slow.
  So all suggestions, comments are welcome.
  Note: TABLE_A REB 700 million, TABLE_B 4 million and TABLE_c is located only 500 RECS
  Thank you!

  Advantage of the fact that aggregate functions more ignore nulls, you could do something like:

  SELECT a.p_id, b.p_name, c.p_desc,
         COUNT(CASE WHEN a.date BETWEEN TRUNC(ADD_MONTHS(LAST_DAY(sysdate),-4) + 1) AND
                                        ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) AND
                         a.m_id IS NOT NULL THEN m_id END) AS countall,
         COUNT(DISTINCT CASE WHEN a.date BETWEEN TRUNC(ADD_MONTHS(LAST_DAY(sysdate),-4) + 1) AND
                                      ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) AND
                       a.m_id IS NOT NULL THEN a.m_id END) AS unique_count, /* entirely possible */
         SUM(CASE WHEN a.date BETWEEN TRUNC(sysdate,'YEAR') AND
                                      ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) THEN a.amt_1
                  ELSE 0 END) AS total_amt_1,
         SUM(CASE WHEN A.DATE BETWEEN TRUNC(sysdate,'YEAR') AND
                                      ADD_MONTHS(LAST_DAY(TO_DATE(sysdate)),-1) THEN A.AMT_2
                  ELSE 0 END) AS TOTAL_AMT_2
  FROM table_a a, table_b b, table_c c
  WHERE a.p_id = b.p_id and
        b.pt_id = c.pt_id
  GROUP BY a.p_id, b.p_name, c.p_desc
  

  The two statements inside the COUNTY box return a.m_id or NULL. A simplified test case is:

  SQL> WITH t as (
    2     SELECT 1 m_id, 9 dt FROM dual UNION ALL
    3     SELECT 1 m_id, 6 dt FROM dual UNION ALL
    4     SELECT 2 m_id, 9 dt FROM dual UNION ALL
    5     SELECT 2 m_id, 6 dt FROM dual UNION ALL
    6     SELECT 1 m_id, 5 dt FROM dual UNION ALL
    7     SELECT 2 m_id, 5 dt FROM dual UNION ALL
    8     SELECT null m_id, 9 dt FROM dual)
    9  SELECT count(CASE WHEN dt BETWEEN 6 and 9 THEN m_id end) cid,
   10         count(distinct CASE WHEN dt BETWEEN 6 and 9 THEN m_id end) cdid
   11  FROM t;
  
         CID       CDID
  ---------- ----------
           4          2
  

  I'm not entirely sure that you really need the IS NOT NULL predicate a.m_id in the instructions BOX, but I left it for more security.

• How to count the total number of records with distinction?

  Hello guys
  
  I have a report that contains a list of the types of company and other attributes as follows:
  

  Shipto               Company Type             GC Code               Measures
  A                         cc                             x                          100
                                                             y                          200
                                                             c                          120
  
  B                         YUT                         I                            200
                              cc                           U                           98
  
  G                         Maid                        rt                           200
                             YUT                        TT                         300
                             JTE                         TY                         400
  
                             
   

  The list goes on and... "Business type" appears is not the highest or the lowest... I would like to see what is the total number of different company types we have. By this report, there should be 5, but if I count or count (*) or rcompte, I actually get the total number of lines in the present report, which is not what I want...
  
  If someone could help me to find the total number of company types?
  
  Thanks in advance

  Have you tried this one?

• Getting Sum, Count, and Distinct Count of a file

  Hi all, this is a question of UNIX.
  
  I have a large flat file with millions of records.
  col1 | col2. col3
  1. a | b
  2. c | d
  3. e | f
  3. g | h
  footer *.
  
  I'm supposed to do to calculate the sum of the [= 9] col1 col1 County [= 4] and a separate account of col1 [= c3]
  
  I would like if you avoid external commands like AWK. Also, can we do the same thing by creating a function?
  
  Please keep in mind that the file is huge
  
  Thanks in advance

  Yes, I suppose that it is very much inappropriate for answering this question here, I just like awk too] :))

  where x is the file:

  sum(col1) : awk -F\| '{col1+=$1}END{print col1}' x
  count(col1): wc -l x | awk '{print $1-2}'
  count(distinct col1): cut -d\| -f1 x|sort -u|wc -l|awk '{print $1-2}'
  

  Perl would be a much more effective tool to use here... try a perl forum :)

  Now i want to calculate rolling backword frequency of each ilo id and output should come like as based Frequency winodw 
  
  e.g. if frequency window is 2 then 
  
  
  USERID   CLO_ID C_DATE                     ILO_ID  I_DATE                        FREQUENCY
           1         11 05/01/2009 00:00:00        216 06/01/2009 00:00:00          2
           1         11 05/01/2009 00:00:00        215 05/01/2009 00:00:00          3
           1         11 05/01/2009 00:00:00        214 04/01/2009 00:00:00          3
           1         11 05/01/2009 00:00:00        213 04/01/2009 00:00:00          2
           1         11 05/01/2009 00:00:00        212 03/01/2009 00:00:00          2
           1         11 05/01/2009 00:00:00        211 02/01/2009 00:00:00          1
  
  1. For each ILO ID, go back number od days given as Frequency window (in our case its 2)
  2. calculate the number of ilo_id in that range
  3. number of ilo_id is the frequency of that ilo_id

  How can I achieve this.

  Re-installing win7 Professional 64 bit on a computer hp laptop.  You had to make a record of killing to eliminate the problem.  Previous installation went smooth. All files transfer and expand, all the way to the installation of updates. Then it counts down to restart windows. Then nothing.

• missing in Windows 7 desktop calendar.

  I was counting a lot on Windows desktop calendar that I had with Vista.  My current computer runs on Windows 7, which doesn't seem to have a Windows desktop calendar.  Is there a download available Windows that provides an interactive desktop calendar, or one that can be downloaded for free from another reliable source?

  There is a calendar gadget, if that's what you're looking for.  Just right click on an empty space on the right side of your screen and click gadgets.  On the desktop, and then drag the calendar.

  Windows Live Mail has a calendar.

  And if you click on the digital clock in the lower right corner of your screen, you'll see a calendar there as well.

  I hope this helps.  Good luck.

• Windows 7 Theme is changing automatically to "unsaved theme".

  OK so I am running Windows 7 on a almost new ASUS K50IJ and my problem is with the customization, more precisely defining a theme/desktop background. When I change my theme and save it and delete all the other themes everything works very well, exactly as I want. The problem is when I shut down my computer, and then start it upward, the theme has magically changed back to a theme "non-registered" with a completely different environment than what I chose.

  Ive been reading forums all day and tried some things listed there, but did not get anything to work properly. This is driving me CRAZY and I need it fixed. STAT. Also, I don't know if it's relevant or not, but a lot forums that I met, people with computers ASUS have been encountering this problem. I wonder if it is a software that comes standard on the ASUS computers that is counter the themes of Windows 7. Just a thought.
