• Point cloud with missing data and 3 sets of data

  Hello

  I'm doing a scatter diagram that has 3 sets of data in it (i.e. 3 plots on the same graph), except that 2 of my sets of data have a missing value while my third set has all the values. I end up getting 2 lines that are disconnected. I can't just remove the line containing the missing data for the 2 sets of data because since my category axis is time, my data points get shifted and no longer appear at the right time. This is the chart that I have.

  

  Thank you.

  Hi Gabrielle,.

  If there is a diagram of dispersion, the x axis is a value axis. If you have auto selected for the min and max values on this axis, the scale may change when you remove the data point, 15, 85, but the rest remains in the same position relative to the values on each axis of ordinates. What change will be , however, is the curve on which 15 85 approached a local y maximum.

  Scatterplots will always leave a gap in the line/curve of connection where there are a pair of missing data. There are two ways to close the gap.

  If the chart is an essentially linear relationship, you can use a calculated value is pair up with the lack of value x. The downside of this is that the representation of this point will be indistinguishable on the map of the other data points, measured.

  A better way would be to make two tables, one with the full data set, the other with the partial sets, but with the pair missing completely removed.

  Adjust the cards the same size and have the same scales on each axis, then just remove one of the cards except the data points, the curves connecting the data points, the x axis of ordinates and the legend showing the color and the forms used to plot each series.

  Give a graphic a transparent filling and place it in front of the other.

  Kind regards

• How to get the data from more than 100 domains in bulk API V2.0?

  Hi all

  I try to get data from Eloqua by APIs in bulk because of big data.

  But my Contact 186 fields (more than the majority of export limitation 100). I think I need to get all the data by 2 exports.

  How could I corresponds to 2 parts of a line and join together?

  I'm afraid that any change of data between 2 relative to exports 2 synchronizations would make different order.

  FOR EXAMPLE:

  1. any document is deleted or modified (if it matches do not filter) after obtaining data of the first part and before getting the second part, then everyone behind it would have back in part result.

  2. the data in some fields (included in both parts) are changed between the 2 synchronizations, then the values of the second part are more recent but the values of the first part are old.

  All suggestions should.

  Thank you

  I don't know that you ever go to work around the fact that things will change in your database while you are synchronizing the data. You have to have a way to create exceptions on the side of the synchronization.

  If I pushed Eloqua data to a different database and had to contend with the problem of matches change while I'm syncing, I would create a few additional columns in my database to track the status of synchronization for this folder. Or create another small table to track the data map. Here's how I'd do.

  1. I would have two additional columns: 'mapped fields 1' and '2 fields' mapped. They would be all two datetime fields.
  2. I would do only one set of synchronization both. First of all, synchronize all records for email + 99 fields. Do the entire list. For each batch, the datetime value of the lot in 'mapped fields 1' column.
  3. I would then synchronize all folders of email + other 86 fields. Repeat the entire list. For this batch of the datetime value of each batch in their 'mapped the 2 fields' column to now().
  4. For all records that had only 'mapped fields filled, 1' but' fields mapped 2' was empty, I would be re - run the second query Eloqua API using e-mail as the search value. If no results were returned, I would remove the line. Otherwise, update and the value 'mapped fields in 2' now
  5. For all the records that were only "fields mapped 2', I re - run against the first email query API Eloqua, fill in the missing data and define 'mapped the fields of 1' of the current datetime object." If the record has not returned, remove the line because it is probably not in the search longer.
  6. Finally, the value 'mapped fields 1' and 'mapped 2 fields' empty for all records, since you know that data is synchronized. This will allow you to use the same logic above on your next synchronization.

  Who is? It is not super clean, but it will do the job, unless your synchronizations take a ridiculous amount of time and your great data changes often.

• Fill in the missing dates with level

  Think im a bad thing. I have some data that missing dates (days) and I want to just fill in the missing days with 0

  This sql is to look right or I'm doing something wrong:

  SELECT H.URL, H.V_DT, NVL CNT (P.CNT, 0))

  SELECT CAL. URL, CAL. MIN_DATE + LEVEL AS V_DT OF)

  SELECT the url, MIN (D) MIN_DATE, max (D) MAX_DATE

  USER_LOG_TMP2_VW where the url is not null and current_url (select distinct URL of USER_LOG_TMP_VW)

  GROUP BY URL

  After MAX (D) > MIN (D)) CAL

  CONNECT IN CAL. MIN_DATE + LEVEL < CAL. MAX_DATE

  -GROUP BY URL, CAL. MIN_DATE + level

  ): LEFT JOIN USER_LOG_TMP2_VW P ON P.URL = H.URL AND F.F. = H.V_DT

  There are only about 75 unique URL and when I run the present it works but I can't count because there are so many lines when it should be, perhaps a few thousand. the oldest date of min goes back only a few months.

  im getting strange results. As if I add a specific url like this (below)... it works perfectly for this url. But when I go out as above where it captures all urls... it gives me weird super results. As the dates twice for duplicate URLS.

  SELECT H.URL, H.V_DT, NVL CNT (P.CNT, 0))

  SELECT CAL. URL, CAL. MIN_DATE + LEVEL AS V_DT OF)

  SELECT the url, MIN (D) MIN_DATE, max (D) MAX_DATE

  OF USER_LOG_TMP2_VW, where url is not null and current_url to (select url from USER_LOG_TMP_VW where url = 'http://testing123.com/test/test"")

  GROUP BY URL

  After MAX (D) > MIN (D)) CAL

  CONNECT IN CAL. MIN_DATE + LEVEL < CAL. MAX_DATE

  -GROUP BY URL, CAL. MIN_DATE + level

  ): LEFT JOIN USER_LOG_TMP2_VW P ON P.URL = H.URL AND F.F. = H.V_DT

  I was not post create it for the views with her but I think that maybe im just something wrong with the level.

  I tried the group according to the level of url cal.min_date +, but for some reason it just keeps running and the query never ends.

  Hello

  Depending on your needs and your version, you may want a CONNECT BY clause like this:

  CONNECT BY LEVEL< max_date="" +="" 1="" -="">

  AND PRIOR url = url

  AND PRIOR SYS_GUID () IS NOT NULL

• Alert entered for the missing data file

  I'm trying a simple payback scenario: remove a data file to a tablespace that is normal when the database is running, and the data file has been saved.
  
  Before, the control point ends normally (I guess that still retains the file inode handle Oracle). When I choose to dba_data_files, the error occurred:
  

  SQL> alter system checkpoint;
  
  System altered.
  
  SQL> select count(*) from dba_data_files;
  select count(*) from dba_data_files
                       *
  ERROR at line 1:

  ORA-27041: unable to open file
  Linux Error: 2: No such file or directory
  Additional information: 3

  To my surprise, nothing has been recorded in the alerts log. And no trace of the files not generated in udump. And Oracle has refused to restore the data file when he was running.
  
  The message appeared in the journal of alerts when trying to stop the database. After abort shutdown (Oracle refused to stop immediately) and restart the instance, I was able to restore and recover the data file.
  
  This is the expected behavior? If so, how you would detect files of missing when db is running?
  
  
  Oracle: 9.2.0.6, OS: RHEL3

  1. it has not detected by the control point caused by a switch logfile because the file is not actually missing. Like other - inded you! -have, Unix/Linux, you can remove a file at any time, but if the file is in use, the inodes are allocated and the process using it continues to see it very well because it. Because, at the level of the inode, it IS absolutely still there! Either by the way, it is needless to say to make a logfile switch, because as data files are concerned, which does nothing, that the command of alter system checkpoint that you already tried.

  I used to do demos of how to recover from the complete loss of a controlfile in Oracle University classes: I would like to make a burst of rm *.ctl commands and then significantly question the command checkpoint... and nothing happened. Very demoralizing the first time I did it. Deliver a force of startup, however here the inodes are released at that time, files are actually deleted and start falls in nomount State. Bouncing the instance was the only way I could get the data base to protest against the removal of a data file, too.

  2. No, if a file has disappeared in a way allowing to detect Oracle, it wouldn't matter if the folder was empty because he's worried the presence/absence of the datafile headers. They need to be updated, even if nothing else does.

  3. it would be in the alerts log if SMON has detected the lost file at startup (one of his jobs is, explicitly, to verify the existence of all the files mentioned in the control file). CKPT would not trigger an alert, because concerned, all right. Inodes are still held, after all. Your attempts to create tables and so forth inside the lost file do not generate display errors (I think) at this time, it's your server process that seeks to do things for the file, not CKPT or pre-existing other background process, constantly running.

  4. it's specific to Unix, anyway, that Linux is a Variant.

• variable sharing, missing data, the timestamp even for two consecutively given

  Hello

  I have a problem with missing data when I read a published network shared variable.

  Host VI:

  In a host of VI on my laptop (HP with Windows XP Prof.) I write data to the shared Variable 'data '. Between two consecutively write operations is a minimum milliseconds of wait time. I use it because I want to make sure that the time stamp of each new value of data is different then a preview (variables shared the resolution is 1 ms)

  VI target:

  the VI target cRIO-9012 bed only of new data in the way that it compares the timestamp of a new value with the time stamp of the last value on a device in real time.

  Problem:

  rarely, I'm missing a data point (sometimes everything works fine for several hours, transfer thousands of data correctly above all of a sudden failure occurs). With a workaround, I'm able to catch the missing data. I discovered that the missing data have the timestamp exactly the same, then the last point of data read, is so ignored in my data 'legal '.

  To summarize, the missed value is written to the variable shared host, but ignores the target because its timestamp is wrong, respectively the same as the last value, despite the host waits for a minimum of 10 milliseconds each time before writing a new value.

  Note:

  The shared Variable is hosted on the laptop and configured using buffering.

  The example is simple only to display the function of principle, in real time, I also use a handshake and I guarantee that there is no sub - positive and negative.

  Simplified example:

  

  

  Question:

  Anyone has an idea why two consecutively data can have the same timestamp?

  Where timestamping (evil) Finally comes (System?)?

  What would be a possible solution (for the moment with shared Variables)?

  -> I tried to work around the problem with the clusters where each data gets a unique ID. It works but it is slower that comparing the timestamps and I could get performance problems.

  It would change anything when I animate the shared on the RT System Variable?

  Thanks for your help

• Compare and get the data in the tables (see post for details)

  I have two tables TableA and TableB. I struggle to write a query to get the dates of TableB (instead of TableA dates) where TableA dates don't coincide with the tableB (beginning and end).

  Example 1: For account A1234,.

  TableA got 2 rows 1/31/2014-3/3/2014 (which corresponds to TableB row), but TableA got another rank 31/01/2014 - 31/01/2014 that corresponds with the date of TableB Begin. In this case, I'm looking for output as below,

  Use TableB start and end date and combine number two rows from TableA for this account

  ACCOUNT	TableB_BEGIN	TableB_END	AMOUNT
  A1234	31/01/2014	03/03/2014	100.0000000000

  Example 2: For the B7777 account.

  TableA end date aligns with the end dates of TableB for this account, in this case I want out put as,.

  Use TableB start and end date and get the amount of TableA

  ACCOUNT	TableB_BEGIN	TableB_END	AMOUNT
  B7777	05/04/2013	06/05/2013	200.0000000000

  Example 3: On behalf of D5555,.

  Even a TableA line corresponds with TableA, there are two other rows in TableA matching start date with TableA and correspondence with the end date with TableA, in this case, that I put as,.

  Use TableB start and end date and combine number three rows from TableA for this account.

  ACCOUNT	TableB_BEGIN	TableB_END	AMOUNT
  D5555	08/08/2014	10/09/2014	1100.0000000000

  Example 4: To account E6666.

  Hi Frank,.

  Your query/solution works very well, but I forgot to mention something in the first post...

  Please insert these additional lines and try the request again.

  TableA Additional lines:

  1. Insert into TABLEA (ACCOUNT, BEGIN, END, QUANTITY)
  2. values ('F9999', to_date (January 2, 2014 ',' dd-mm-yyyy ""), to_date (3 January 2014 ', 'dd-mm-yyyy'), 999.0000000000);

  TableB Additional lines:

  1. Insert into TABLEb (ACCOUNT, BEGIN, END, QUANTITY)
  2. values ('A1234', to_date (March 3, 2014 ',' dd-mm-yyyy ""), to_date (4 March 2014 ', 'dd-mm-yyyy'), 999.0000000000);

  Question 1:

  The table has a rows for A1234 account (i.e. the time period different than the ranks for the same account)

  one is A1234 31/01/2014-03/03/2014, A1234 03/03/2014-03/04/2014

  Your query that returns two rows for A1234 account (which is what I want), but the amount is messed up.

  	ACCOUNT	BEGIN	END	TOTAL_AMOUNT
  1	A1234	31/01/2014	03/03/2014	1100
  2	A1234	03/03/2014	03/04/2014	1100

  Except:

  	ACCOUNT	BEGIN	END	TOTAL_AMOUNT
  1	A1234	31/01/2014	03/03/2014	101
  2	A1234	03/03/2014	03/04/2014	999

  Question 2:

  In some cases TableA will have an account (F9999), but the TableB don't. I can just this line by making the Left Join right join?

  I don't get the results with additional data. I get 1099 for two lines where account = 'A1234 '.  I get 1100 as the amount on the line with the account = "D5555.  You did it other changes to data?

  Except:

  	ACCOUNT	BEGIN	END	TOTAL_AMOUNT
  1	A1234	31/01/2014	03/03/2014	101
  2	A1234	03/03/2014	03/04/2014	999

  Still, I don't see why you want to 101 for the amount of the first row.  Why not 100?

  How can you know which rows from tablea should get attached to what rows from tableb, when the account is not unique?

  Maybe you want something like this:

  SELECT a.account

  b.begin

  b.end

  SUM (a.amount) AS total_amount

  FROM tablea a

  ON a.account = b.account JOIN tableb B

  AND a.begin BETWEEN b.begin

  AND b.end

  AND a.end BETWEEN b.begin

  AND b.end

  GROUP OF a.account, b.begin, b.end

  ORDER BY a.account

  ;

  but I guess just to your needs, and guessing is not a very good or reliable way to solve problems.

  Question 2:

  In some cases TableA will have an account (F9999), but the TableB don't. I can just this line by making the Left Join right join?

  Yes, it looks that you want an outer join.  What happened when you tried?  As always, post your code, the exact results you want from the given sample data, as well as an explanation of how you get these results from these data.

• Get the data in table of javafx

  Bat I can get the data in table as:

  [code]

  for (int i = 0; i < dtm.getRowCount (); i ++)

  {

  for (int j = 0; j < dtm.getColumnCount (); j ++)

  dtm.getValueAt (i, j);

  [/ code]

  But how can I do this with javafx table? I google and google and google and no luck.

  In JavaFX make data are stored on a basis per line. Each line contains an element of type T (where you have a TableView), and each column specifies a value using a callback function that determines the value of the column of the value of a particular line.

  You can browse the data simply by practice

  for (T item : table.getItems()) {
    // ...
  }
  

  And then get the value of each column for each element of the given line, since you "know" what each column represents.

  For example, in the example of JavaFX documentation, you could do:

  for (Person person : table.getItems()) {
    String firstName = person.getFirstName(); // value in firstName column
    String lastName = person.getLastName(); // value in lastName column
    String email = person.getEmail(); // value in email column
  }
  

  If you want something really generic, you can try

  for (T item : table.getItems()) {
    for (TableColumn col : table.getColumns()) {
      Callback, ObservableValue> cellValueFactory = col.getCellValueFactory();
      CellDataFeatures cdf = new CellDataFeatures(table, col, item);
      Object cellValue = cellValueFactory.call(cdf).get();
      // do something with cellValue...
    }
  }
  

  If you have little chance to this need, unless you write some kind of framework. (I just typed it here, you may have get dirty you with guys a little to make things).

  Maybe you have a few virtual machines with more than one network card?  If so, this line that gets the Type to interconnect the virtual machine would produce no output for these machines.  To manage the virtual machines with more than one NETWORK card, edit the "$report.Network =...". "line to something like:

  $report.Network = ($_ | Get-NetworkAdapter | %{$_.Type}) -join ","
  

  This will give a single type for virtual machines with a NETWORK card or a string of separation by commas of type names for virtual machines with more than one NIC

  How does do for you?

• Using of "get the N first lines only" does / * + FIRST_ROWS ([N]) * / redundant index?

  I know FIRST_ROWS indicator shows the optimizer to minimize the time of the first row.  I know that the new feature of 12 c for "fetch [FIRST |]» [NEXT] [N] LINES [ONLY |] WITH LINKS] "get first/next N lines only / with ties" will implement the query using ROW_NUMBER().  Should I leave hint in case it improves performance, or the clause FETCH FIRST made this redundant suspicion?

  Hi Wes and Hoek,

  Oracle said on the indicators in the 12 c setting guide. Each version of this statement becomes stronger.

  The disadvantage of the advice is additional code that you must manage, audit and control. Tips have been introduced in Oracle7, when users have little recourse if the optimizer generated suboptimal plans. Because changes in the database and host environment can make obsolete tips or negative consequences, it is a good practice to test the use of indicators, but use other techniques to manage the execution plans.

  Oracle provides several tools, including how to set up SQL, SQL plan management and SQL Performance Analyzer to solve performance problems unresolved by the optimizer. Oracle strongly recommends that you use these tools instead of advice because they provide new solutions like the change of environment data and database.

  Oracle presents advice in V7, basically as an admission that its optimizer based on CSSTidy based cost did not get things right all the time and tried to get rid of them since. In addition, the preferred method of setting when you are browsing the major updates was to review advice to remove them. It will be interesting to what extent can it be pushed in V12.

  In what concerns the first lines index and ROWNUM limiting, unless you just try to get the garbage data, it's meaningless without the presence of an ORDER BY. Once you have an ORDER BY, the query must retrieve all the data before it can return anything. The exception to this rule is if there is an index that the database can use to retrieve already ordered data, that is to say on the order of columns. Therefore, the essence of the indication of FIRST LINES. It will be aggressive looking in the index in favor if the index is in line with the order of. (Try the setting of a SIEBEL instance if you need proof)

  I don't have a 12 c to test at the moment, but looking at the examples of Martin, it appears the optimizer is aware of the new windowing function in the new FETCH FIRST/NEXT structure and selects a plan that gives the best answer. If you go through the effort to review suggested rownum limited requests to remove the tips if possible, maybe you should just rewrite with new windowing function.

  As we can see that there is no missing date against empno 7369 so it is displayed in the output and empno 7499 is missing dates from 09-Sept-12 to 11 - sep-12 and 23-26-sep-12 sep-12.
  7521 Empnos and 7788 has no entry in the table of emp_shift where these empno dates do not appear in the 01-sep-12 and 30-sep12

• Download of CSV using Browse point (don't get no data found error)

  Hello
  
  I use procedure below to download CSV in my table.
  
  CSV is to have null values in some places ex: 1,.

  3,
  4,0.696
  
  below the procedure works fine when I am downloading as CSV: 1.0

  3.0
  4,0.696.
  
  My table is seen as two columns, and I get no data found error when downloading a CSV of null values.

  Chambers,

  You can use wwv_flow_utilities.array_element to avoid any no_data_found. The function does not raise any errors. For example, for the line which only have a value of table when you wait 2, it can be useful.

  EXECUTE IMMEDIATE 'insert into table_name@Schema1 (col1,col2)
      values (:1,:2)'
      USING
        wwv_flow_utilities.array_element(v_data_array,1),
        wwv_flow_utilities.array_element(v_data_array,2);
  

  Kind regards
  Christina
