  Hello

  Whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) of all the tables involved, so that people who want to help you can recreate the problem and test their ideas.

  Also post the exact results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  See the FAQ forum: Re: 2. How can I ask a question on the forums?

  and: Re: 4. How can I convert rows to columns?

  Swivel (which is the generic name for what you want to do) assume that you can tell, by looking at each input line, you can specify what columns of output that the row will affect.  In this case, it seems that you need to derive a column like this, perhaps using the ROW_NUMBER analytic function.

• How to add two lines when the second row is not visible, but also gets the first data line too?

  Mr President

  Jdev worm is 12.2.1

  How to add two lines when the second row is not visible, but also gets the first data line too?

  I want to add two lines like below picture, but want the second to remain invisible.

  

  I asked this question but my way of asking was wrong, that's why for me once again.

  Concerning

  Try to follow these steps:

  1. in the database table to add the new column "JOIN_COLUMN" and add the new sequence "JOIN_SEQ".

  2. Add this new column in the entity object. (You can add this in entity object by right clicking on the entity object and then select "Synchronize with database" then the new column and press on sync)

  3. in your bookmark create button to create only one line NOT 2 rows.

  4 - Open the object entity--> java--> java class--> on the entity object class generate and Tick tick on the accessors and methods of data manipulation

  5 - Open the generated class to EntityImpl and go to the doDML method and write this code

    protected void doDML(int operation, TransactionEvent e)
    {
      if(operation == DML_INSERT)
      {
        SequenceImpl seq = new SequenceImpl("JOIN_SEQ", getDBTransaction());
        oracle.jbo.domain.Number seqValue = seq.getSequenceNumber();
        setJoinColumn(seqValue);
        insertSecondRowInDatabase(getAttribute1(), getAttribute2(), getAttribute3(), getJoinColumn());
      }
  
      if(operation == DML_UPDATE)
      {
        updateSecondRowInDatabase(getAttribute1(), getAttribute2(), getAttribute3(), getJoinColumn());
      }
  
      super.doDML(operation, e);
    }
  

    private void insertSecondRowInDatabase(Object value1, Object value2, Object value3, Object joinColumn)
    {
      PreparedStatement stat = null;
      try
      {
        String sql = "Insert into table_name (COLUMN_1,COLUMN_2,COLUMN_3,JOIN_COLUMN, HIDDEN_COLUMN) values ('" + value1 + "','" + value2 + "','" + value3 + "','" + joinColumn + "', 1)";
        stat = getDBTransaction().createPreparedStatement(sql, 1);
        stat.executeUpdate();
      }
      catch (Exception e)

        catch (Exception e)
        {

• How oracle inserts data in columns

  Hi guys, just a quick question. When we have a primary key on 4 columns, and we have, say 20 million lines, and we want to add an additional line. How oracle checks if the data on the primary key is unique for recording added compared to the 20 million lines. They actually compare recording added to all rows in the table?

  Not the entire line, it compares the 4 columns in the INDEX against the 4 columns in the new row.

• How to make a line intersect with a path at random angles?

  How to make a line intersect with the anchor point of a half circle when you want the line to continue beyond the anchor point of the half circle at an angle to randomly?

  Now that I saw your picture, I understand the problem. You must make the careful construction work.

  Take a look at this:

  

  Start by drawing your circle. Drag the ruler guides (here dotted lines) so that they snap into its Center C.

  Drag another landmark of rule to your point of origin O.

  With the Pen or line tool Segment a line of O to T A. setting by the eye as precisely as possible with the end of it A directly selected.

  A copy of the line OA rotate 90 °. Using smart guides, drag the new line until it crosses the center of the Circle C.

  Direct, select the end of your original line and move it to T until the smart guides say "cross".

  Now, with the selected OA line use the scale tool. O-click and drag to 45 degrees by holding the Shift key. Your line will extend over its own length.

  In order to take account of the OA line across the circle just use the Reflect tool. Select the line, an Option, click the horizontal guide and copy reflect across the horizontal axis through the dialog box.

• How to choose the line PFI to use on the port of the 5761?

  I understand that the VIDEO that I use on my DAC 5761 allows me to access 8 PFI lines.  However, when I access my 5761 devices in the project window by clicking the "+" next to the name of the module, I see that 'PFI Input' and ' output PFI.  I tried to get this to send a signal in the past, but I have been unable to determine how to select the line PFI I want to use.   How can I select the PFI line?

  Any ideas?  I was able to get the my AWG PFI (5422) for work and it is amazing.  I want to order an attenuator digital step for a ground penetration radar that I develop.

  Your time and your help is very appreciated.

  PS: I have worked with this PXI system (chassis, embedded controller, FPGA digitizer 5761 and AWG) for 1 year and I am afraid that it is time to learn this one way or another.

  Good day!

  -Daniel

  I found the solution. In addistion to the node which is visible in my previous post, there must be a node to enable PFI write with an entry of decimal number indicating the line is activated. Then, there must be a node PFI active connector, set to true. Not sure if the node of the latter is really necessary, however. Otherwise above examples should work as is.

  Hi Piya,

  I run your code, and according to your logic that it works correctly.

  It's adding that line only once because according to your logic that one line can be added to MDT, if you do not want to add line on each click on the button, follow these steps:

  selectedindex1 = chart [obj1.getSelectedIndex ()];
  selectedindex2 = shade [obj2.getSelectedIndex ()];
  selectedindex3 = rolls [obj3.getSelectedIndex ()];
  selectedindex4 = cuts [obj4.getSelectedIndex ()];

  Lbl1 LabelField = new LabelField("");
  Lbl2 LabelField = new LabelField("");
  LabelField lbl3 = new LabelField("");
  LabelField lbl4 = new LabelField("");
  If (LBL1. GetText(). Equals("") | LBL2. GetText(). Equals("") | lbl3. GetText(). Equals("") | lbl4. GetText(). Equals(""))

• How oracle to count the number of users of Hyperion

  Hello

  Can I find out how Oracle count of users for Hyperion Planning? I disabled some dummy accounts in the Production environment, but they exist the planning app security group. Will be what they considered authorized users?

  Thank you

  As I see it is provisioned to users who could potentially access the system, so I assumed that disabled accounts could not access to the system so don't are not counted, just my opinion, I do not speak for Oracle

  As suggested, it always better to speak to the representative of account for any clarification.

• How Oracle called the hidden for the function-based index columns?

  
  I came across an interesting problem today.  Statistics object for a schema that have been created on the basis of data X have been imported into a 'identical' to the database schema Y.

  The problem is that, on the basis of data X a group of hidden columns associated with index based service (FBIs) were named SYS_NC00182$ to SYS_NC00191$ and on the basis of data Y the same hidden columns were named SYS_NC00183$ to SYS_NC00192$!  The consequence was that statistical column for an FBI data base X have been used for a totally different FBI on the database Y.

  Now, of course, if this was g 11 or 12 c I could just create virtual columns and those of the index.  In this way the names of the columns would be compatible on databases.  However, it is a 10g database, and I do not have this option.

  I am curious to understand how Oracle generates these hidden column names.  I'm also curious if, in 10g, there is a way to identify the name of a column hidden for an FBI that doesn't involve a statement explain plan running on a query that uses all the expressions of the FBI for the table.

  The names of $ SYS_NCnnnnn are based on the internal column id - what is loosely based on the order of creation of the FBI. If you delete a column the column internal ids (after this column), which means the names for the SYS_NCnnnnn$ the change.  An opportunity to explain your results is that a (real) column on the X data table fell, but the column still exists on the database Y.

  If you want to get the link between the current internal name and expression, then you can start with dba_ind_expressions - and create a customized version of the view - e.g @.

  Select c.intcol #, c.name, io.name, idx.name, bo.name, base.name, c.default$, ic.pos #.

  of sys.col$ c, sys.obj$ idx, basis of sys.obj$, sys.icol$ ic.

  sys. User$ io, sys.user$ bo, sys.ind$ I

  where bitand(ic.spare1,1) = 1 / * expression * /.

  and (bitand (students, 1024) = 0) / * not bmji * /.

  and ic.bo # c.obj = #.

  and ic.intcol # c.intcol = #.

  and ic.bo # base.obj = #.

  and io.user # idx.owner = #.

  and bo.user # base.owner = #.

  and ic.obj # idx.obj = #.

  and idx.obj # i.obj = #.

  and however # (1, 2, 3, 4, 6, 7, 9)

  /

  The first two columns in the select ones that I added to the initial view definition.

• Transaction is written to the log file and it is not written to undo tablespace. During a failure of the system how oracle rolls back the transaction.

  Hi all

  My question is:

  Transaction is written to the log file and it is not written to undo tablespace.

  During a failure of the system how oracle rolls back the transaction.

  I have already provided the answer, you ignored if well (you seem to only read the responses by people of your country).

  Redo log is always written * first * before * writing to the data block (redo log writing is much more aggressive). So it DOESN 'T MATTER if you lose these scriptures of rollback segment.

  Valuation: rear roller followed by roll forward, using redo log files and/or archive redo log files.

• How to change a line in Illustrator CC?

  Hello

  This may sound silly, but I don't know how to change a line. I can't change other basic objects, such as the square, but not a line. There is no brand 'ladder' around it, and when I try to scale sorter/more long anyway, is deformed in a wrong direction, because my hand is not stable. I had no such problems to the CS6. I hope someone knows how to solve.

  You must select object > shape > expand shape so he can behave as it did in CS6.

• How Oracle Clusterware Oracle RAC and 3rd-party Clustering with them

  I have some questions on how Oracle, Oracle RAC and 3^rd party clustering CLusterware fit between them.

  Q1. My understanding is that the Infrastructure Grid Oracle Clusterware is Oracle's Clustering solution that allows applications to cluster? that is, it is a general clusterware solution to compete with those already on the market. Is this correct?

  Q2. So why CARS is necessary for the Oracle cluster databases? An Oracle database is not just considered one application like any other? So why can not just use you GI / Clusterware to gather what you would do for any other application? Why so you need RAC to the Clusterware Summit?

  Q3. Is it is possible to combine an Oracle database using 3^rd party of clustering and not use Oracle Clusterware and CARS at all that is can you say cluster, an Oracle database using say Sun Clusters, Clustering AIX or Linux native same clustering?

  Q4. If the RAC is purely for Oracle Cluster databases - what is with the title "Real Application Clusters"? What's real on this subject?, what to ask?

  Q5. I also read that RAC can use 3^rd party of clustering. However if you decide that this is the case, then you need to install Oracle Clusterware when even (I think for interconnection must be created to allow the merger with Cache between Instances of node?).

  Is this the case?  If yes why never bore you with 3^rd party clusters? -Since you will have to install Oracle Clustering anyway - and I probably have to license (all I can think about is the scenario that you already have a cluster of 3^rd party in place and you decide that you need to use the same material for a database cluster)?

  All wisdom greatly appreciated,

  Jim

  Yes, with 10g, you had to use the CRS, and with 11g, to use the GI.  For 9i RAC, you would use Verits Cluster and Sun Cluster or anything else.

  11g RAC to GI.  As above, you can use clusterware extra if needed.  I gave the example above where to a 10g RAC we used the CRS to the cluster database/listener/vip and allowing groups of volume and filesystem in HACMP cluster.  File systems were not shared, but could switch to another node failure node, who has been treated by HACMP.  The volume of the groups containing the raw devices were shared volume groups.  For 11g, I never used extra clusterware on top of CRS and have always used ASM which is part of the GI.

  The application provider only certified database to run on 10g on AIX with raw devices.  What is strange about that?  It would be unusual that you probably expect to use ASM instead of raw devices, but it is what it is.

  See the following Note of Oracle for more information: using Oracle Clusterware with vendor Clusterware FAQ (Doc ID 332257.1)

  It is perhaps easier to explain if you can explain what problem you are trying to solve?

• How to remove a line in a PDF document?

  How to remove a line in a PDF so it's not an empty space left after that I have remove the text in the line I want to delete?

  Basically you don't have. PDF is not a file format of spreadsheet or word processing (see ISO 32000 for a description of this PDF "is").

  After enjoying a few eve readings long winter of the ISO standard, you will come to realize this PDF is no 'tables', the 'lines', the 'columns '...

  Content objects are "painted" on page PDF "canvas" - kinda sorta a paint-by-numbers thing.

  That said you can use content redaction Acrobat Pro for slick tool. Maybe not as elegant as you want, but if done correctly the content is gone (for sure, absolutely, forever).

  Be well...
