• How triggers can be created in the table?

  Hi all
  How triggers can be created in the table?
  is 12 or as far as we can?

  There is no technical limit to the number of triggers you set (or, at least, not one that any rational person has never touched). He usually would not make sense to have more than one trigger of a given type on a particular table, even if you can come up with situations where you can have multiple triggers of the same type on a single table.

  Normally, when people ask this question, it is because someone (foolishly) he asked in an interview. Frequently, the interviewer is trying to determine if you know how many types of triggers there is no if you know if there are some esoteric limit on the number of triggers.

• How to get a list of the tables more fragmented in Oracle?

  Is there a SQL on how to get a list of the tables more fragmented in the Oracle DBMS?

  Update the statistics on the table and try this, you should see very fragmented tables upstairs with high wasted_space.

  select table_name,round((blocks*8),2) "size (kb)" ,
                              round((num_rows*avg_row_len/1024),2) "actual_data (kb)",
                              (round((blocks*8),2) - round((num_rows*avg_row_len/1024),2)) "wasted_space (kb)"
  from dba_tables
  where (round((blocks*8),2) > round((num_rows*avg_row_len/1024),2))
  order by 4 desc
  

  I changed the query a little because the ORDER BY will not work if we concat | ' Ko ' with the column because this makes the output a character column data.
  And added a WHERE condition to see that these tables where the total size is greater than the actual size of data.

• Pagination of the table in a query with table Panel

  Hello

  I need to implement paging in a table as long as the results of a query which makes the user, the table that the query is run has several records, 40000 or more.

  I searched but I can't find a way to apply what I, some links show me how to insert the pagination on the part of the table, but if I only do when I want to see a different page, let's say 500 or 1000, it takes too long to display the data of that specific page. I'm guessing it will retrieve all the data from the query and read it all so it can show what I want.

  Another way is to control the amount of data to be returned from the view object (VO), but I am unable to perform paging efect component table in my file jspx somehow.

  I think I should change my VO both my component so I can get the effect I want, but I don't know how. Properties that I need to change to achieve this.

  If I set the af: non paginated table mode the number of pages do not appear.

  Then maybe you can use the code from this blog to do it manually:

  http://www.Ateam-Oracle.com/adventures-in-WebCenter-skinning-aftable-with-custom-pagination/

  The only optimization that I think is missing is somehow when I select the page from the list of results, will retrieve only the data on this page.

  Yes and for this you must range Paging in VO (so the result of the query may be limited by the size of the range).

  But, as I mentioned in my first reply, range of paging is bug in 12.1.3 then maybe the same applies to 11.1.1.7

• How to dynamically add columns to the table

  Hi all

  I'm new to ADF and need help on sub condition.

  We have created a ViewObject on the EMPLOYEE table that has under columns:

  EMP_ID,

  EMP_NAME,

  DEPARTMENT,

  COST_CENTER,

  BUSINESS_UNIT

  COUNTRY

  GCODE

  We need to create a page in the ADF with employee table to show only below the columns

  EMP_ID,

  EMP_NAME,

  DEPARTMENT,

  COST_CENTER

  Later, if necessary user should be able to add other columns to the page dynamically.

  Can you please advice on how to implement this feature.

  Thank you.

  Kind regards

  Vidya

  Hello.

  There could be a simple solution, which is to use the component PanelCollection.

  Drag ' drop your VO to a page and create a Table with all the attributes.

  For columns that emp_id, emp_name, cost_center, set the Visible property to false.

  Put the PanelCollection component on your page and drag your table inside.

  When you run the page you will see the view menu in the upper left corner of the table above. You can show/hide columns in this menu.

• ADF: How to get all rowKeys for the table displayed in the page

  Hello

  I have table "COMPANY" where the 'COMPANY_ID' column is the primary key. I created a page simple jspx with:

  (1) a text entry to accept new IDs of company

  (2) Insert button.

  (3) af:table which displays all available in "SOCIETY" company ID

  When the user tries to enter a company code that is already present in the table I want to compare with the keys of the row of the table displayed below and if it's an already existing, I would like to send a friendly message for the user and put an end to the movement.

  So, how to extract all line keys to compare?

  It depends on what you expect. If you issue count (*) you ask Oracle "how many lines there. If you issue a County () you ask Oracle 'how non null values for are there. "

  delete from 
  where  is null;
  

  Ideally you would simply place a NOT NULL constraint on the column in question, thus prohibiting NULL values into the system (assuming that your business needs, it is that the column MUST always have a value).

• How to set current row in the table after use the button tab on inputText

  Hi all
  My first post.., I am beginner in ADF and I'll try to explain my problem.
  
  For now we use ADF 11 g (11.1.1.4), in a jsff page I have a table with a column of inputText.
  On the the inputText valueChangeListener, I invoke a method in a bean viewScope that call an EJB method, make some services to the EJB on the modified line. After that, I update the VO and the table (because other values in the row have been changed) and reset the focus on the inputText even modified by the user with javaScript, because the focus was lost after updating.
  So far, everything works fine.
  
  When I use the arrow keys to change the selected line in the table, this is excellent work (focus is always in the inputText next or previous), but if the user tries the key tab allows you to change the current line, the inputText on the line that has the focus, but the current row in the table is not changed (I think that is normal).
  
  My question: How can I change the current line after the tab key in this case?
  
  I don't know if it is really clear, not easy to explain, do not hesitate to ask for more details.
  Thanks in advance.

  Hello

  My question: How can I change the current line after the tab key in this case?

  Use a client event to listen to the keyboard entry and intercept the tab. Use af:serverListener to call the server to set the rowKey on the table and deliver a PPR for the table to repaint

  See example 11 on http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples

• How do find no data in the table

  Hi all
  
  I have 250 table in my diagram and when I query like this

  order by object_name CSA
  
  
  Some tables have no data in it. How to find the tables that not have data or records
  
  Thanks and greetings
  Srikkanth.M

  Hi Srikkanth,

  First of all, if you are only interested in object TABLE type, so you should better use dba_tables instead of dba_objects.
  Then, assuming that your statistics are up to date, it would look like:

  SELECT *
    FROM all_tables
   WHERE owner = 'MATTELLI'
    AND num_rows > 0
   ORDER BY table_name ASC
  

  Otherwise, you can go with a subquery and a 'select count.

  Hello

  I have an example here in the construction of a dynamic array markets.

  http://www.assuredynamics.com/index.php/category/portfolio/building-dynamic-tables/

  You must select the line and then go to object > Binding palette and set it to repeat. You can set the minimum and initial number to what you want.

  The form should be saved in a dynamic form of XML in the Save as dialog box.

  Also the page must be set to Flowed, so that as the table grows, push another object down. In addition, you need to configure the paging settings so that the flow of the page as the number of lines is superior to a single page.

  Give a start and if you need more help,

  Ok. You can then use the external table. But I would not. Table ICET is an existing table? And you must add the data stored in the file c:\res.txt to the table? If so, the best way, in my humble OPINION, would be SQL * Loader. With the external table, you will need to create one and then do something like INSERT icet SELCT of external_table. Selecting in the outer table will read c:\res.txt and load it into a temporary table that will be then inserted in icet taable. With SQL * Loader file c:\res.txt will be loaded directly into the icet table.

• How to store data points in the table

  I'm new to labview and I am trying to store the output of the frequency of 'measures pulsed VI' in a table, add everything together and divide by the length of the array. I don't want a table of numbers to be shown on the indicator. Just average 25 numbers.

  Basically, I want to do, but in labview.

  arrayIndex = 0;

  for (int i = 0; i)<=25;>

  {

  NewData = somedata;

  MyArray [arrayIndex] = newdata;

  dataAvg = dataAvg + myArray [arrayIndex];

  arrayIndex ++;

  }

  dataAvg = dataAvg / 25;

  I have attached my attempt, but its probably a very poor attempt. (The N on my first loop for was 25 when I tried to run the VI)

  Thanks in advance

  You need n number of bed DAQmx to take the average of the number n of steps of the pulse. Silly to take 500 what whatsoever when you have a single DAQmx reading which returns a single measure. As I said, you can use a registry to offset or point-by-point inside the loop. Or, run a number n of the acquisition of times with a loop and moves the pulse measurement in the table for automatic indexing and calculate an average, when all acquisitions are made.
