Why is the "Number of Rows" to a report seems to be cached in the session?

• number of rows affected by report

  Hi all
  
  I want to show the number of result rows to a query on a report page. my test query returns 52 sets of data (also when I execute the same statement with select count (*)) but the #TOTAL_ROWS variable # said that 11.
  I think it's because I put the value in pagination of row 10...
  
  is there a known issue with this? is #TOTAL_ROWS # only supposed to show the number of lines of recoveries?
  
  Thanks in advance hendrik

  Hendrik,

  This will not work unless you paging system is set (with pagination). You can always count your rows in a separate process and get this value by using the same SQL as in your report.

  Blocks of database entries are by DBWR, not dedicated server process: so if a session database issues some write actions that they cannot be declared with corresponding wait events in the user database session, but you will see waiting for associated events to make journal entries because database session must either wait to VALIDATE the execution returns (redo written log is made by LGWR and not by dedicated server process) or the order of log file (also made by LGWR).

  You can see sort in http://download.oracle.com/docs/cd/E11882_01/server.112/e16508/process.htm#BABHJDHD
  and in the complete picture and great http://landingpad.oracle.com/webapps/dialogue/ns/dlgwelcome.jsp?p_ext=Y&p_dlg_id=9575302&src=7027600&Act=54.

• 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

• Limit the number of rows retrieved

  We have the need to limit the number of rows retrieved in a table for some users.
  
  We tried to put this by adding a policy that limits the number of rows. Here is the code:
  
  
  create or replace function
  usu01_access_policy
  (obj_schema varchar2, obj_name varchar2) return varchar2
  is
  d_predicate varchar2 (2000);
  Start
  If the user = "PEPE01" then
  d_predicate: =.
  "rownum < 11';
  on the other
  d_predicate: =.
  ' 1 = 1' ;
  end if;
  Return d_predicate;
  end;
  
  This code works well when you query the table like this:
  
  Select * from usu01;
  
  the number of rows retrieved is 10.
  
  But when we define a clause 'where' the query does clause 10 recovered lines before, getting only the lines of the first 10 with the condition 'where' = true.
  
  Is there a way to limit the number of retrieved rows from a table, but by first applying the 'where' clause to the whole table and later the ' rownum < limit ' condition?
  
  Thank you

  Why do you limit the number of lines of output? It is a customer number, not a database problem, I would say.
  Which should be resolved within the query itself. Using rownum without orderly subquery also return different results on each run.

• How to determine the number of rows in the database and save the result to a local variable?

  Hello

  I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

  I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

  Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

  It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

  -RautSa

  Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

  I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

• get the number of rows affected by their table top

  Hello, I need to count the number of rows updated in table form. In the process of ApplyMRU, I can use the string substitution #MRU_COUNT # to show the lines updated in a success message, but I need to get this value and store it on a table. Any help would be much appreciated. Thank you.

  For that you would benefit from the APEX$ ROW_STATUS integrated substitution string.

  1. create a page element display only (in my case P15_UPDATED_ROWS) Save Session State set to Yes and the Type of Condition is set to never.

  2. Add a calculation after the shows with a Type of static assignment and calculation value 0 to reset the counter whenever the page is sent.

  3. Add an On submit - after calculations and Validations process of PL/SQL page linked to your tabular presentation with a Status of Type PL/SQL Expression and Expression 1 :apex$row_status = 'U' and the code of the following process :

  :p15_updated_rows := :p15_updated_rows + 1;
  

  If you don't actually means "day" in the strict sense, and then change the status of process to include possible APEX$ ROW_STATUS 'C', 'U', and "D" values as needed. If you want to count all created, updated and deleted lines, do not add the condition to the process, but make sure the extended run is set to createand changed lines.

• See the number of rows affected the performance of sqlplus to a sql file

  Hello

  It's just we have a sql file that contains a bunch of select/update/insert statements.

  I have a unix script that calls sqlplus on this sql file. However, at the exit I don't get the number of rows affected.

  Without adding any code in the input sql file, how can I change the code of sqlplus shell script to print the number of rows affected for each statement in the sql file?

  The SQL_FILE of entry content is:

  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 :
