• Query took too much time when adding new column to the table and the index set on this

  I added a new column to the table that contains thousands of records. and created the composite index with three columns (those newly added + two existing column)

  for the specifics. TBL table there are two columns col1, col2

  I added the new column col3 to TBL and created composit index (col1, col2, col3).

  Now for all the records in col3 is NULL. When I choose on this table, it takes too long...

  Any idea what my I do bad., I have check the query plan, it is using the index

• Add new data to the table in a log file

  Hi all. I am new to Oracle and I need to also write new data table in a logfile on Linux in order to live in the display screen. My first thought was to write a trigger, and after some research on googled around, I finally came to this:
  
  create or replace trigger foo_insert
  After Insert on foo
  for each line
  declare
  f utl_file.file_type;
  s VARCHAR2 (255);
  Start
  s: =: new.udate | '-' || : new.time | ' ' || : new.foo | ' ' || : new.bar | ' ' || : new.xyzzy | ' ' || : new.frobozz | ' ' || : new.quux | ' ' || : new.wombat;
  f: = utl_file.fopen ('BLAH_BLAH', 'current.log', ' a');
  UTL_FILE.put_line (f, s);
  UTL_FILE.fclose (f);
  end foo_insert;
  
  It seems properly to add new data in the log file as new inserts occur, but open and close the file each time are of course not optimal.
  In the app real new lines could have inserted every second or two. How can I optimize it? In addition, the log file will be archived and turned every day, so there must be a way to effectively report the relaxation of the oracle to reopen the case.
  
  
  Thank you!

  As Ed suggested you need to think this through a few others and refine the requirements.

  You said "I am new to Oracle. So you may not realize that anything a trigger didn't REALLY EVEN HAPPEN! The transaction can still be restored by Oracle or by the appellant. Want that all the 'hiccups' look too? If this isn't the case, then you can not use a trigger to do this. You need the process that translates the trigger being called to do logging after the data is stored.

  It should be noted that this requirement is before we can offer solutions to a problem.

  Assuming you want the trigger record all attempts change the data, then the best way I know to do that is to minimize the work does the trigger.
  Another fundamental principle is to follow the advice of the Ed and have a clear separation and distinction between "what" should be done and 'how' to do it.

  To minimize the trigger work change proposed Nicosa approach. Create an AUTONOMOUS_TRANSACTION stored procedure that handles the 'how' and just have the trigger to transfer data to the stored procedure values. The trigger provides data; He doesn't know, or care, what is done with the data.

  The stored procedure is then free to use the files, a table, write to a file or any other method is proving to be the best. You can change the methods without affecting the trigger.

  A queue or table may contain data, but again once you need to think about the obligation. Do you need fair access to data only once? Now, you want a "tail". But what happens if this requirement change tomorrow? You won't have to redesign the architecture.

  With a queue once you delete the queue data it won't here later if you want to get it again. With a table you can take as long as you want.

  I would like to start by using a table to store the data. If you use a sequence number or "insert_date" value, you can always query the data of interest. The table just collects data. He does not care how to use data.

  So, by using proven design principles and knowing that the requirements are for the most part unknown and may change unexpectedly, I would be:

  1. create an AUTONOMOUS_TRANSACTION stored procedure that accepts the parameter data and the thicket in a simple logging table.
  2. change your trigger to call the procedure to step #1
  3. create another procedure that performs a query of 'tail' for you will depend on 'insert_date' number or sequence. This query can write data to a file or return a cursor ref that your script can use to provide data for display.

  The approach described above takes each step in the process relatively independent of the other stages.

  Until put you the finishing touches to the requirements that you do not want to lock up your initial design.

• Whenever I call a VI I get old data with new data in the table

  I selected 'clear indicators when it is called' in my properties VI, execution. Yet, whenever I call the VI, the table of data is growing. My main VI implements my USE, and then call the sub - VI, which sets up an instrument measurements, then reads the results and transmits data. I then change the UUT to the next State and repeat the same task sub - VI to get again the same measures. The main VI changes the mode of WEAR it three times, so call the sub - VI three times. The last call of the Subvi back all three sets of data together, which is OK. My problem is, when the main VI ends and I run another USE, I get the new set of data as well as the complete list of data from the previous run. I found a similar problem answered here on the forum who suggested I should 'clear indicators when it is called', and so I did. It still has not fixed my problem. Any idea?

• Added new line in the table

  Hello
  
  I have a table inside a panelCollection. When I press the button Add a new row (plu green) the empty line newly added appears in a random place in the table, but I want to appear as the first line of the table (top of the table). How I do that?
  
  Thank you very much
  Will do

  Will do,

  It is a weird behavior that was introduced in JDev 11.1.1.4. We fixed this in the next version by adding the new line always above the current line.

  You can do two things:
  -Make sure that the size of the range of the iterator binding is greater than the number of rows displayed, in this case the new line will be created directly below the current line
  -extend the JHeadstart TableBean class, override the createNewRow method and create a line in the first line

• Adding new partition in the table are

  Hello
  
  Oracle 9i
  Windows 2003 operating system
  
  The main entry/exit table is one of the base tables that has a large number of records and a very high success rate, and to avoid poor performance that may occur in such cases, Oracle Table partitioning technique has been examined in the early stages of the implementation of the system.
  
  Unfortunately, the technique used to divide data based on the year of the transaction considered the year 2010 as the last specific partition, so all records created after this year is gathered in a single partition and this may cause poor performance in the years to come.
  
  Are required to add another 10 partitions; up to the year 2020 taking into account that the downtime should be close to zero.
  
  Ground:
  
  According to my knowledge
  
  for this, so we can create a new table with the same columns and add required 10 more partitions, and if we take 2 scenarios like
  
  export/imp
  insertion in the new table select * from < table > old
  
  What is the best, and if we take exp/imp, if her take a few hours of time to complete a task... what will happen for the updates as insert, update, and delete in this time what will be the impact on the import... I mean if all committed tarnscations... These tarnscations automatically add to the table are not.
  
  Please tell me what is the best and the tarnscations should not effect... pls tell me how excatly we can complete the task.

• Functional test Oracle Forms: adding new row in the Table

  Hello

  I try to create a Test Script for creating order sale to R12.  I use OpenScript Version: 12.5.0.1 Build 287

  I am able to create the script for all orders with less than 9 lines.

  Currently, it has more than 8 lines, the script does not work. The threshold is unable to find the object to line 9.

  "//forms:textField [(@name ='LINE_ORDERED_ITEM_DSP_" + getVar ("{{setLine}}") + "" ")] .

  The reason could be, when I scroll down to line 9 in the form, I guess the name of the textfield object is changed.

  If everyone faced the similar problem, please throw some light on this.

  Thank you

  Guna.

  Hi Guna,

  You will need to provide the "maxvisiblelines" for the part of lines to BBA. This must be done at the component level. When you define a component itself, you must specify the value for maxvisiblelines

• How to add data to the table using Manager POST for restful Apex application

  Hi all

  I managed to create a service application web Manager restful using GET for the Restful service module. I am able to get the data in row on the presentation of a table row id in the application. But I can't find an appropriate example, how the new data in the table can be posted or deleted. I created a POST handler for a URI scheme and look forward on how to proceed. Any help would be really appreciated.

  Source for the POST Manager:

  Start

  insert into ALL_BOOKS values(:id,:book);

  end;

  Also created 2 parameters id and the book.

  Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

  If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

• Analyze the table of variants

  I have a request, where we read binary data by Ethernet to high speed (~ 500 Hz). This data consists of hundreds of measures and other variables of all types (floats, integers, strings, etc.). I already have the code to analyze these data and store it in an array of variant.

  Now, I would like to take this array of variant and map each element to a particular variable.

  Because the data is stored in a predefined sequence (element #1 = speed, element #2 = power, element #3 =...), I considered looping through the array of varying and using a structure dealing with a case for each index of the array (see attachment). However, it is very heavy because the case structure has hundreds of cases (one for each element of the array) and it is impossible to insert a new item in the structure of business without dialing manually anyway.

  Can someone point me to a simpler implementation? If I was using C, I'd probably memcpy binary data directly in a structure aligned bytes. Is there any equivalent in LabVIEW, you use clusters?

  (Note: using LabVIEW 2014)

  Very well.  I thought about such a VI came out probably somewhere in vi.lib.

  However, I have also been concerned about the case where the table of variants isn't an different LabVIEW application.  In this case, I don't expect that the name and information of TypeDef would be in the variants, as specific to LabVIEW, so I was thinking something like this:

  

• How to add data to the table changed in sql developer at Apex and vice versa

  Hello

  I had tables of database with sql developer. But now, I have modified the database (new tables added + changed the data in the tables). However, in the Apex, I the old database. Is it possible to get the new Apex database with the data of the table changed so this database in both places (sql and apex developer) is exactly the same... Also the other way around.

  Thank you

  The database schema that contains the tables, is it associated with the workspace even you are searching through the APEX product t development?  Why I'm asking is, if they are the same schema, the tables that you MODIFIED should be appear in the sql for APEX workshop part.  Now reports and forms will NOT see the changes (unless you have actually added or updated definitions for column).

  Can you explain what exactly you were doing the SQL Developer to the tables in your schema?

  Thank you

  In this way, you can specify the Boolean parameter or omit it if you choose to use named parameters:

  It is a dynamic array, where a new line can be inserted using a button. Is that the dynamic nature of the question? ID hate to cancel all the flow dynamics and programming just to add a column, and then reapply them all.

  Hello

  You do not add the columns in the object > palette (screenshot 2) of the Table. I suspect that the problem is that it is not enough on the page (in the content area) to add the column. In the screenshot 1, if you look at the width of the column highlighted from the space to the right of the table, you will see that a column can be added due to restrictions of space.

  Reduce the width of the column highlighted (temporarily), and then add a column. Once added, you can resize the columns to match the width of the page.

  Hope that helps,

  Niall
