• Count the number of rows in each table

  I have a list of table names, how to write a query to find out the number of rows in each table.
  
  Select the table table_name from all_tables where owner = 'XXX' and num_row > 100
  or

• Number of rows in each partition is displayed with a NULL value for a table partitioned in user_tab_partitions. Why?

  I created a table and partitioned on the date of the entry and added a local partitioned index.

  Now, I use a query to extract "num_rows" of user_tab_partitions to know the number of rows in each partition.

  Getting this value as null num_rows, wonder why?

  After looking to explain the Plan after interrogation ("select * from my_table1 where entry_date = 1 January 2015" ;))

  to find out if she actually partitioned table and its data in different partitions, I interpreted in effect because the query plan had a line like Partition_range (Single).

  My Question is:

  (a) is actually partitioned data (have I misinterpreted the Explain plan)

  (b) why is the num_rows null column in the query (Pasted below)

  (c) also in addition what difference it would have been if I had created a Global Index instead of the Local Index in my case?

  The following code Snippet:

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

  create the table my_table1
  (
  roll_no number constraint my_table1_pk primary key,
  date of entry_date
  )
  partition of range (entry_date)
  (
  PARTITION data_p1 VALUES LESS THAN (TO_DATE (December 31, 2014 ',' DD-MM-YYYY ""));
  PARTITION data_p2 VALUES LESS THAN (MAXVALUE)
  );

  
  create an index only my_table1_indx on my_table1 (entry_date) local;

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

  I now insert two lines:
  insert into my_table1 values (1, to_date ('01-01-2015', ' dd-mm-yyyy'));
  insert into my_table1 values (2, to_date('01-02-2015','dd-mm-yyyy'));

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

  These have been inserted successfully, now using the query below shows num_rows column as null. I don't know why?

  SELECT table_name, num_rows, high_value, nom_partition
  Of user_tab_partitions
  where table_name = 'MY_TABLE1 '.
  ORDER BY table_name, nom_partition;

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

  
  

  (a) is actually partitioned data (have I misinterpreted the Explain plan)

  Yes, it is partitioned. You can query this particular partition SELECT * FROM my_table1 (data_p1) PARTITION to check that.

  (b) why is the num_rows null column in the query (Pasted below)

  As already mentioned that you have not collected statistics.

  (c) also in addition what difference it would have been if I had created a Global Index instead of the Local Index in my case?

  In fact, you have created two types of indexes without knowing (can be)! One is not partitioned (although this column is not partition key) and another is partitioned (LOCAL). They are MY_TABLE1_PK and MY_TABLE1_INDX. You can check that USER_INDEXES.

  You can read this article to get an early jump on the partitioning of decision. Partition: Partition decisions

• 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.

• Game max fixed the number of rows in a table

  Hi all
  
  I created a table that should contain only one line and avoid the possibility to add other lines to it, I used the following:
  

  CREATE TABLE <table_name> (
      <field_1> <field_type> unique,
      ...
      <field_2> <field_type>
      CONSTRAINT <field_1_ck> CHECK (<field_1> = <value>) 
  );

  It works, but it seems a bit heavy for me... Is there a better way to define a fixed/maximum number of rows in a table?
  
  See you soon,.

• 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!

  Nom_de_variable: Total_Row_Count

  Type of variable: Variable discount

  Definition tab:
  Data type: digital
  Action: No persistent

  Refresh the tab:
  Schema: provide the schema of your repository to work and be

  SELECT log.nb_row
  THE journal of snp_step_log, snp_scen_step step
  WHERE log.nno = step.nno
  AND step.scen_no = (SELECT scen_no FROM snp_scen_step WHERE step_name='<%=odiRef.getPrevStepLog ('STEP_NAME") % > ')
  AND log.sess_no = '< % = odiRef.getSession ("SESS_NO") % >' code at low
  AND step.step_name = ' < % = odiRef.getPrevStepLog ("STEP_NAME") % > '

  Note: add this variable after the stage of interface in your package (after the interface anywhere you can place), you can add this variable before ODISendEmailNotification in your package

  call this varciable * #Total_Row_Count * in the Notification of ODISendEmail

  for example :

  Data has been fulfilled successfully in < % = odiRef.getSysDate () % >
  Total no of lines filled are: * #Total_Row_Count *

  it will work

• Displays the number of rows in the table displaying a named criteria query data

  I created a test named for my View, called 'Criteria1' and Criteria1 to create a group of ADF with Table query. I want to display the number of rows in result when a search is performed. How can I do?
  
  Thanks in advance,

  As mentioned, you can add outputText and you must give OutputText partialTriggers as query component your Id. Thus, when you give a search on the query component, it will refresh the outputText with the number of lines.

  
  ID = "ot1" partialTriggers = "id of the component of motion here" / > ""

• 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

• Display the option button if the number of rows in the table is equal to 1

  I'm having issues there buy maybe a simple script out there.

  I have a table which can have up to four lines. If the table contains only one row, an option button can be clicked to change the format/entry of cells in this row. I have to hide this box of a user option, if they added more of a line to the table and make it available again if they reduce the number of lines to one.

  I have everything else works well (radio buttons change line format, add/delete rows in the table using buttons, number of rows in the first column)

  Anyone have any ideas?

  See you soon

  Bobby

  You can place it in the code that adds more lines when running... If you have questions send the fomr to [email protected] so I can check it out...

• Add the number of rows in the table on the Page Framework OA

  Hi all
  
  I need to add a line at the bottom of a table in the OA framework to display the number of lines for the underlying table VO. Can someone point me in the right direction to get there?
  
  Thanks in advance!
  
  Kristopher

  Hi Kristopher,

  As directed by your post, my understanding is that you want to have a line at the bottom of the table that contains a field that displays the number of rows found in the t... RT?

  You can implement the same in the following way,
  You can add a footer to your table and add a messageStyledText point in it. At this point, you can assign the value of VO.getFetchedRowCount ().

  Hope this is what you are looking for.
