• BEEP and Siebel: limit the number of records displayed in a table

  Hi all
  I use BEEP with Siebel. For example, my XML has a set of 50 activities. These activities are of a different type and different date. Now, I want to show:
  
  5 activities the newer type A in a table.
  5 activities the most recent type B in another table.
  5 activities the most recent type C in another table.
  
  I tried using the position() method, but since I use the same set of activities 3 times it will not work. The reason is that after you sort the activities in descending order of creation date, I could end up having 5 recent activities of type A digit 4, 9, 17, 23 and 31. That's why I can't use <? If: position() < 6? >.
  
  The 'worst' solution would be to create a link of multiple values in Siebel for each type of activity and prior filtering of activity types in the object link, so I could use the solution above to limit the records per table. But it is really more practical in my opinion.
  
  All welcome ideas on how to do this inside the model.

  If you couldn't do something similar to this in your model:

  <=5]?>

  If you wish, send me the sample xml data and a RTF file to [email protected] and I can take a look.

  Thank you!

• Get number of records in all tables

  Hello
  
  I try to get the number of records from all the tables by using a dynamic query. I don't know how to put the placeholder value. I tried the code below.

• 450 million rows in the table.

  Hey guys,.

  I hope you all have a great day.

  My question is this, lets say I have a table that has rows in it 450 million, and there is even more data to load into the database.

  For example, if I text or excel spreadsheets, files what is the best 'method' to get this table into tables?

  Thank you

  Number of existing rows in a table isn't anything by simple insert.

  You can use sql loader or external table to insert data from text files or spread sheet.

• Can I get the total number of records that meet the conditions of a query using the Table API?

  Hello

  A < row > TableIterator is returned when I ask operations using the index of tables. If I want to get the total number of records, I count one by one using the returned TableIterator < row >.

  
  

  Can I get the total number of records directly meets the conditions of the query?

  I can get the total number of records directly the request of the meeting of the conditions of CLI using the command Global table - name tableName - count - index index-name-field fieldName - start startValue-end endValue.

  Can I get the same results using the Table API?

  I used MongoDB and NoSQL Oracle for about a year. According to the experience of the use of these dbs, I think mongoDB querying interface is powerful. In the contras, the query interface is relatively simple, which results is a lot of work that is usually a long time in the client side.

  Hello

  Counting records in a database is a tricky thing.  Any system that gives you an accurate count of the records will have a hotspot of concurrency on updates, namely the place where the counting is maintained.  Such a count is a problem of performance in addition to competitive access problem.   The problem is even more difficult in a system widely distributed such a NoSQL database.

  The CLI has overall command that counts, but does so by brutal force - iterate keys that correspond to the parameters of the operation.  This is how you must do this within the API.  There is not a lot of code, but you have to write.  You certainly want to use TableIterator TableAPI.tableKeysIterator (), because a key iteration is significantly faster than the iteration of lines.  Just one iteration and count.

  If you use TableAPI.multiGet () and a key with a touch of brightness full then, in fact, count the results as they are returned in a single piece (a list).

• difference in number of records in the table of audit

  Hi all

  We strive to remove lines of verification based on timestamp(sysdate-30) table(sys.aud$). The command I used below.

  SQL > set lines 200

  COL OWNER FORMAT A15

  Select TABLE_NAME, nom_tablespace, OWNER, num_rows, STATUS, DEGREE, TABLE_LOCK, LAST_ANALYZED, PARTITIONED, USER_STATS from dba_tables where TABLE_NAME = '& TABLE_NAME';

  SQL > SQL > type table_name value: AUD$

  OWNER, TABLE_NAME, NUM_ROWS STATUS DEGREE TABLE_LO LAST_ANALY BY USING NOM_TABLESPACE

  --------------- ------------------------------ ------------------------------ ---------- -------- ---------- -------- ---------- --- ---

  SYS AUD$ 934991 SYSTEM VALID ACTIVE 1 08/07/2012 No. No.

  SQL > delete / * + parallel (aud$ 8) * / of sys.aud$ where NTIMESTAMP # < sysdate-30; (I don't know why I put NTIMESTAMP #, although I see # aud TIMESTAMP column $ table, the above query, I got from sr dba)

  3140994 deleted rows. (reason why so many records have been deleted I see 934991 lines from dba_tables view)

  
  

  After that I saw the difference in number of records.

  
  

  SQL > select / * + parallel (aud$ 8) * / count (*) from sys.aud$ where TIMESTAMP # < sysdate-30;

  COUNT (*)

  ----------

  0

  SQL > select / * + parallel (aud$ 8) * / count (*) from sys.aud$ where NTIMESTAMP # < sysdate-30; -> Why there are differences in the number of records if I put NTIMESTAMP #in query)

  
  

  COUNT (*)

  ----------

  50

  Thank you

  Bhavani.

  SQL > SELECT count (*) from sys.aud$ where ntimestamp #.<>

  COUNT (*)

  the script below gives me a correct result.

  If it works well for you, then it works OK for me.

  Realize that Oracle is that I/O block-level.
  As a general rule, any LINE is a single block.
  Realize that is 1 column "count (*)" is correct, then all the columns in the same row are correct.
  This obsessive compulsion to count each COLUMN in each LINE borders on real PARANOIA!

• How to set Max number of rows in a table?

  Hello
  I'm working on a SCADA interface. In this application, there are different tables with vertical scroll bar.
  I prefer to make it visible only initialized lines (I've initialized 40 empty rows in a table with an array of strings). Since the window contains all 40 lines, but only 20 rows, I put the number of lines in the "table properties window" at 20; So I added a vertical scroll bar.

  Now, when a user, do scroll the scroll bar, it can check not only the initializated 40 lines, but any number of lines.
  There is a way to view only a limited number of lines?

  Thanks in advance!

  
  

• number of rows in the table

  Hi master,

  I have a requirement. During the passage of a table, I need to get the number of rows in this table. Sometimes, when I spend 2 or more table names, I need to get the same count of result of lines. I got the below function. but it shows all the rows in the table. I want pariticular tabels only. How I can I get it.

  Select table_name, num_rows from all_tables where table_name in ('EMP', 'Department');  I tried.  I need to a procedure or function. who will pass the name of the table as a parameter and 1 or more than the name of a table if I pass, I need to display information from table name and number of lines.

  Hi IndiMinds,

  Alternatively, you can use in queries. :

  Odd:

• ADF table large number of records

  JDeveloper 12.1.2

  I have an engine of research as well as an array of result. In some research, it is possible that the result set is more than a million records. The problem is when the user uses the table scroll bar and quickly tries to go at the end of the result set, weblogic with error, memory, it blocks. What is the best practice to handle this in the user interface?

  I think of several ways to resolve and would like if anyone has experience with one of the following:

  1. when the user performs the search, run select count (*), and determine the number of records search will return. If say greater then 1000, warn the user to refine the search criteria. This seems to have made an extra trip to DB

  2. implementation of the pagination of the table instead of the scroll bar. Is this possible in the last ADF table?

  3. go to the front and back only to say 1,000 records and warn the user that not all records are returned, and that it would be best to refine the criteria. Similar to 1, except no extra trip to DB

  Thanks in advance for comments and maybe the solution

  Insufficient memory is caused by the underlying ViewObject that retrieves and keeps track of all the lines to the position where the user scrolls to the bottom of the table. It is behavior of the VO when the VO is configured with the access mode "Scrollable", which is the default access mode setting. For example, if the user scrolls to the No.100000 line, the VO to get and keep in mind all the lines n ° 1 to No.100000. This means that the table pagination will NOT help you!

  Fortunately, you have two simple options out-of-the-box:

  1. The 1st option is to configure the original Version of extraction does not exceed a fixed number of lines (for example 5000). You can do it in the "General" of the VO definition dialog page. Go to the 'Tuning' section, select the option "only up to line number" and enter the number chosen in the field of text next to it. In this way, what the condition is entered by the user, the VO will seek no more than the specified line number.
  2. The 2nd option is to configure the VO with "Range Paging" access mode rather than the default access mode "Scrollable". With the access mode "Range Paging" the VO not go get and keep in mind all the lines until the currently selected line, but he keeps in memory a few line ranges (for example only a few dozen lines). This way you will not be affected by an OutOfMemory error even if the user scroll down to a millionth line. The downside is that when it is configured with "Range Paging" the VO will have to rerun the query each time when he needs to pick a different range of lines. If the execution of the query is slow to the DB server, this will load the DB server and the user will experience delays when scrolling in a different range of lines.
     Take a look at the documentation for more details here: View object performance tuning (read article 9.1.5).

  Post edited by: Dimitar Dimitrov

  If you decide to use "Range Paging", don't forget to set the appropriate size, which is not less than the usual number of visible lines in your table on the page. If you set the size of the lower range, then the original Version will have to fetch more than a range of lines, which will need more of a running query. The size of default in the definition of VO is 1, but it is not important. The important value is the size of the range that is defined in the iterator binding in the PageDef, which overrides the setting of the VO. The default value for the size of the links of the iterator range is 25.

• by comparing the number of records in the table child

  I have 3 tables below:
  
  Table 1 - Parent Table
  Table table2 child - who has the number of records for each record in Table1 (row_id in Table1 corresponds to par_row_id in Table2)
  Child table table 3 - has that number of records for each record in Table1 (row_id in Table1 corresponds to par_row_id in table 3)
  
  I would like to run an Oracle SQL query to identify all the separate row_id on Table1, for which the number of child records in Table2 does not match the number of child records in Table3
  
  I ask for help to identify the best way to identify these records in the parent table. If possible an example too, please.

• Question on the number of rows in the table bean

  Hello
  
  I have a table with the name of column to column, change the image...
  
  I 100 columns like that, and I set the number of lines to display in the 30
  
  Suppose that when I am in the 55th row in the table by clicking next... I clicked on the image for that particular line, it opens the new page. And now if I select Cancel button on this new page... I go to the previous screen that has table.
  But what my problem is it shows lines from the opening of the table... not the page (55th place) where I went to the new page. Is it possible to go to previously visited set of rows in the table?
  
  Please solve my problem.

  Hello

  When you browse the page, you can capture the index of the scope of the
  current line selected in the object attached to the table view and store
  the session

  OAViewObject oaviewobject = (OAViewObject) oaapplicationmodule.findViewObject ("YourVOName")
  int l = oaviewobject.getRangeStart ();
  pageContext.putSessionValue ("range", l);

  so when you return to the page and in process request you can reset the index of the range as previously selected.

  Range of String = (String) pageContext.getSessionValue ("range");
  int k = (int) Integer.parseInt (range);
  oaviewobject.setRangeStart (k);

  Thank you
