• ITextModelCmds::InsertCmd modifies the data before inserting it to the history

  When I insert characters from a story by using ITextModelCmds::InsertCmd, some characters are converted into a totally different value.  Anyone know how to get the exact characters inserted in the story without InDesign switching what he thinks you want?

  When I export my page as ASCII elements, they get inserted into history as plain text.  If the characters ASCII characters single quote, InDesign converts the values 0 x 2018 or 2019 0 x.  It is originally importing my data items page to fail because the values have changed.

  If there is not a way to avoid this, anyone know where I can find a list of the characters that are converted so I don't know what to expect when importing?

• Check the date in the schema

  Hello

  I'm new on odi and I have to handle this scenario below

  I insert a date in the table at the end of a single package, in another package, I need to check whether this date is equal to the date system and then move to the second stage.

  I reached the date of insertion in the first package with ODI PROCEDURE below using

  Insert dates

  (Select to_char (sysdate, 'YYYY'), to_char (sysdate, 'mm'), to_char (sysdate, 'dd'), the double null);

  Can you please indicate how can I check the second step.

  You could use variable refresh and then check it out under estimate

  for example (in your case):

  Update the variable

  Select

  -case when to_char (sysdate, 'YYYY') + '-' + to_char (sysdate, 'mm') + '-' + to_char (sysdate, 'dd') = dates.year + '-'+ dates.month +' -' + dates.day, 1

  otherwise 0 end of dates where...

  On the second State handed this condition variable 1

  

  PS: why you store date in columns three tank?

  Maybe stored in formats or date format YYYYMMDD

  Hello Marie Lise.
  Here is the code example that you can do to check the Date. Create a function for this, hope this helps

  CREATE OR REPLACE FUNCTION F_DATE(v_date IN VARCHAR2) RETURN NUMBER IS
      v_date1 DATE;
  BEGIN
      select to_date(v_date) into v_date1 from dual;

      Exception WHEN Others THEN

  DBMS_OUTPUT creates only a message. The message may not be displayed, and if this is the case, then the user cannot see it. The DML will still take place.
  I used instead, RAISE_APPLICATION_ERROR to keep the DML does not happen. It displays a message like

  What do you mean when you say "going to match?

  I think that now you're saying that the new values of (class.cid, class.schosen) must be equal to (or "fit") some existing (stu.cid, stu.sid).

  3. thanks for your tip, I learned how to use '{code} '.

  4. it's really goes with the exception of MUTATING_TABLE. So, how do to fix the trigger to show me INVALID_STU EXCEPTION when I try to choose a student does not belong
  a class?

  Don't refer to the table of class in the trigger, and the error table mutation occur. All the information you need are in the stu table, so there is no need to query the table of class, anyway.

• What is the best way to check the data

  What is the best way to check the actual changes in the data, i.e., to be able to see each insert, update, delete on a given line, when it happened, who did it, and what looked like to the front row and after the change?
  
  Currently, we have implemented our own audit infrastructure where we generate standard triggers and an audit table to store the OLD (values at the beginning of the Timekeeping point row before) and NEW (values at the beginning of the point of timing after line) values for each change.
  
  I put this strategy due to the performance impact there (important say least) and because it's something that a developer (confession, I'm the developer) came with, rather than something is a database administrator came with. I looked in the audit of the Oracle, but it doesn't seem like we would be able to go back and see what a line looked like at some point in time. I also watched flashbacks, but this seems like it would take a monumental amount of storage just to be able to go back a week, much less the years currently keep us these data.

  You can either:
  1. set up your own audit custom (as you do now)
  2 flashback Data Archive (11 g). Application for licence.
  3 version check your tables with Workspace Manager.

  Unfortunately, the audit of data always takes a lot of space. You should also consider the performance, as custom triggers and Workspace Manager will perform much slower than the FDA if there is heavy DML on the table.

  Assuming col_b is a DATE, you can do something like this:

  SELECT       col_a
  ,       col_b
  ,       CASE
             WHEN  col_b < LAG  (col_b) OVER (ORDER BY  col_a)
               OR  col_b > LEAD (col_b) OVER (ORDER BY  col_a)
             THEN  '<-- Could be wrong'
         END             AS flag
  FROM       my_table
  ORDER BY  col_a
  ;
  

  I hope that answers your question.
  If not, what exactly is your question? What exactly are you trying to do? You want to change a single column (or the other), such as two columns of follow the same order? It's actually easier to identify which lines are out of use.
  Post a small example data (CREATE TABLE and only relevant columns, INSERT statements), and the results you want from this data.
  In the case of a DML (UPDATE), for example, the sample data should show what looks like the tables before the DML, and the results will be the content of the or the tables changed after the DML.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• Satellite M300 - how do I back up the data before using the recovery disk

  Hello everyone,

  Today, I closed my laptop Toshiba Satellite M300.
  Just after a few seconds, it automatically in service and reported some "boot error".

  She also suggested I put on the recovery CD. When I put the CD, nothing happened.
  After awhile, I read the instructions in the CD cover that says that I have to hold the C button and it will start the recovery process.

  How the process goes, the system told me that all the files that I had in the computer would be removed.
  Is it possible how I could back up my documents before as I recover my Vista?

  I would be very grateful if someone could help me!

  Sincerely,

  Milan

  Hello

  If I understand correctly, you are not able to boot into the Windows operating system; According to the normal starting procedure or by using safe mode. Is this good?

  If Yes, then I don't see many options to get access to the files on the HARD drive.
  What you could try is to remove the HARD drive and use an external USB 2.5 enclosure to connect the HARD drive on another computer.
  Then you could test whether it is possible to access the HARD disk and save the data.

  The Toshiba Recovery disk does not any option that allows you to save the data, the drive formats the HARD drive and erases all partitions.

• Save the data before and after the occurrence of a Trigger Condition.

  Hello

  I am worrking on an application that acquires data from 64 channels and performs many analyses.

  Necessary to implement something is recording the data in the event of alarm condition.

  I've implemented datalogging in many previous applications, but this one is difficult.

  I need to save data for a few seconds before and a few seconds after the alarm has occurred in a single file.

  I thought constantly write data to a file PDM and at the same time deleting the old data, until the alarm trigger occurs.

  but I was not able to do, since I have no blocks to remove data from a PDM file.

  I'm looking for the ideal approach to this recording.

  Any help will be appreciated.

  What I have to do this in the past, use of a queue with loss as a circular buffer.  When you get the relaxation, dump you the data in the queue to your file and then save however many data you want after the outbreak.

  For the purposes of the memory allocation, do not use the queue to rinse.  Use rather a Dequeue element inside a conditional FOR loop with a 0 timeout (reading the queue stops when you have a timeout or you read X samples).
