• How to use the value of the select in SQL queries list

  I have a list with the list of states (P1_STATE) in Page 1. When I send the page, I get the VALUE of P1_STATE in Page 2 to the format: DC:AS:AK. I use the application to display the form in the Page 2 below.
  
  Select *.
  of STATE_REF
  where IN location_id (: P1_STATE)
  
  Now the format of P1_STATE will not work in the query. So it's not fetch all results. Is there a way in which the values of the selection list can be used in SQL queries. Thanks for the help.

  Hello

  Try something like:

  select *
  from STATE_REF
  where ':' || :P1_STATE || ':' LIKE '%:' || LOCATION_ID || ':%'

• The help of SQL DBMS Flashback AS THE SNA

  I would like to use the DBMS Flashback feature in some SQL code to look at the data in a table based on the SNA.
  That is to say.
  Select ename
  of the emp to the SNA 15387125
  where empno = 442
  
  I know that the length of time, you can use flashback to the SNA for controllable is (thought of by default is 900 seconds), but I assure you. I have not changed the DB params on my system, and the above statement works longer than 900 seconds.
  
  If I try to go back to something that happened a few days ago that I get:
  ORA-01555: snapshot too old: rollback segment number 9 with the name ' _SYSSMU9_3490907396$ ' too small
  
  Can anyone confirm what I watch / set up to the time OF THE SNA.
  
  Thank you

  Available at Flashback depends on how the DB_FLASHBACK_RETENTION_TARGET parameter. By default (in 10G) is 1440 minutes (1 day). [url http://docs.oracle.com/cd/B19306_01/server.102/b14237/initparams050.htm#REFRN10233] To learn more.

  Unless you have a particularly parsimonious DBA you must have considerably longer than a quarter of an hour. But not, of course, "a few days". Although this setting specifies an upper limit, and the window of real flashback could be lower if there has been a lot of activity that has eaten up in the region of flashback.

• With the help of sql filter expression

  Hi Experts,
  
  I have a question using "sql expression" in the filters in the responses. Let's say I have a date filter and I wish that the value for this date as max (tablename.colname). Please tell me the syntax for this passage.
  
  Another issue is that I have a date guest data are updated every week we'll tell the data refreshed like this * 01/08/11, 08/08/11 and 15/08/11 *. Now, if I select the 08/08/11 it will display the data
  populated on * 08/08/11 * which is ok, but if I select * 09/08/11 to 14/08/11 * it only shows * 08/08/11 * data. Similarly, if the option * 16/08/11 or 16/09/11 * it should show the latest up-to-date data which is * 15/08/11 *.
  
  Thanks in advance.
  Chak

  OK, if that State is limited as of the last update when your selects a date in guest that is beyond / above the last refresh date.

  This can be a way to do as below:

  – Enter the last updated date in a variable repository. If this variable will always hold a value for the last date discount.
  -In guests, capture the date selected by the user in a variable of presentation and to apply the Sub statement in SQL advanced report.

  DateColumn = case when Timestamp ' @{RBAP} {2011-01-01 00:00:00}'<= valueof("lastrefdate")="" then="" timestamp="" '@{pvar}{2011-01-01="" 00:00:00}'="" else="" valueof("lastrefdate")="">

  RBAP following your presentation and lastRefDate var is your variable rep containing the last refresh date. What would this statement, if the user selects a date that is less than equal to the last refresh date, then report is filtered from this date. Otherwise, the report will be filtered by the value of the date of the last update.

• With the help of SQL, need to display the previous year, current year and the year next to single variable

  Hi all

  We have an obligation to state the previous year, current year and values of the year next as a LOV in the ADF page.

  This is the query that retrieves the previous year, current year and next year. But the result of this query displays values in 3 columns:

  Output:

  2012 2013 2014

  
  

  But I want to display them in a single with 3 rows as column:

  Your right; analytical functions can do that. DENSE_RANK assign a number without gaps, duplicate output when the input is duplicated.
  Do you care which name gets seq = 1 and who gets seq = 2? If this isn't the case, you can sort the names alphabetically:

  SELECT     id
  ,     name
  ,     DENSE_RANK () OVER (ORDER BY  name)     AS seq
  FROM     table_x
  ;
  

  In the output you posted, it appears you want what they classified by the id low associated with each name ('Jean' = 1, 'jane' = 3 and so on). You can get the id low with the analytical MIN function:

  WITH     got_min_id     AS
  (
       SELECT     id
       ,     name
       ,     MIN (id) OVER (PARTITION BY name)     AS min_id
       FROM     table_x
  )
  SELECT     id
  ,     name
  ,     DENSE_RANK () OVER (ORDER BY  min_id)     AS seq
  FROM     table_x
  ;
  

  Analytical functions cannot be nested. In other words, you can not say

  ... OVER (ORDER BY MIN (id) OVER ...)
  

  That's why I used the got_min_id of the subquery.

• TopLink grid 11g: conversion of SQL queries to the filters of consistency

  I would like to know how efficient the conversion of SQL queries for filters of coherence is wen search an object in the cache coherence. TopLink does something as instruction cache cache filters consistency as well? In this regard, you have number of performance?
  
  Thank you very much!
  
  Ming-Wen

  TopLink grid currently has a rudimentary filter cache that allows TopLink to only translate NamedQuery once. This allows TopLink grid to reuse the same filter on subsequent runs of this NamedQuery.

  select distinct(a.item_number)
        ,a.quantity - b.quantity
  from QUANTITY_ONHAND_ATP a,BACKLOG_ATP_LT_CW b

• How to find the sql queries executed in one day with the sql and runtime text

  Hi Experts,

  Please tell me the sql query to find out the queries executed on a particular day and the runtime and the sql text of the query.

  Please reply urgent.

  Thanks in advance

  Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

  AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

  To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?
