How to Extend a View Object in OA Framework R12. View Object extensions in R12 are possible but inherently buggy.
I've performed several but was not able to post a "bug-free" entry until now. This thread will show how to get through all the wizards and successfully deploy a VO extension in R12. Some of the steps are redundant and designed to avoid errors that the JDev IDE might throw. Hence, the product is not free of bugs but it can be used to complete an extension. For information on how to perform VO extensions in prior releases of Oracle Applications, see this article: How to Extend a View Object in OA Framework The View Object selected for this exercise is from the Employee Directory functionality in Oracle Applications.

Scrolling down through the available attributes you will see there are many available but none involve the Address DFF. FAQ Jdeveloper.fr _ Aout 2007.pdf (Objet application/pdf) [Performance] Select avec trois grosses tables. Bonjour, Il est vrai que connaitre le modèle est primordial dans le tuning des requêtes. J'ai essayé de bien faire dérouler toutes les opérations de 1 jusqu'à 17 en me concentrant sur les deux pavés (8 et 9 -->7) et (13,12,14,11--> 10) On voit bien que les deux opérations 7 et 10 conduisent les opérations filles (8,9) et (13,12,14,11) respectivement.
Ce qui a retenu mon attention ce sont les opérations 13 et 10. Documentation ISNet 29 Groupe ISNET - Datawebhouse - Data webhouse. R12 Internet Expenses FAQs « Oracle Application Financial. Posted by Mahmoud Elemam on October 23, 2010 Internet Expenses 1.

Les secrets de la fonction DECODE - Aide Oracle. La fonction decode sous Oracle permet de faire un traitement de conditions sur les données (que ce soit au niveau de la donnée ramenée ou au niveau du filtre de la requête).
Ainsi, on transforme la donnée dans une requête SQL, sans passer par un language informatique supérieur (PL, ou autre) : decode({valeur de test}, {valeur de comparaison}, {valeur retournée en cas de correspondance}, [{valeur de comparaison}, {valeur retournée en cas de correspondance}, [ ... ]], {valeur retournée si aucune correspondance n'est trouvée}) Soit, par exemple, la table personne :create table personne ( civilite varchar2(5 char), nom varchar2(80 char), prenom varchar2 (80 char), date_naissance date, date_deces date ); alter table personne add constraint chk_choix check (civilite in ('M.
Hint oracle et choix du plan d'exécution - Aide Oracle. Lors d'une requête SQL, Oracle construit dans un premier temps son plan d'exécution (execution plan).
C'est ce qui lui permettra de savoir comment accéder aux données. Pour construire ce plan, il s'appuie sur des règles qui sont paramétrables : en mode RULE, si la colonne possède un index, il faut utiliser cet index. Mais depuis la 8i, le mode CHOOSE (CBO) utilise, en complément de ces règles, les statistiques relatives à ses tables et index ; dans ce cas, si la colonne est indexée mais que le nombre de lignes à parcourir est très faible, il choisira de ne pas utiliser l'index et de faire un FULL SCAN sur la table. Comments. Hints Hints are comments in a SQL statement that pass instructions to the Oracle Database optimizer.
The optimizer uses these hints to choose an execution plan for the statement, unless some condition exists that prevents the optimizer from doing so. Hints were introduced in Oracle7, when users had little recourse if the optimizer generated suboptimal plans. Now Oracle provides a number of tools, including the SQL Tuning Advisor, SQL plan management, and SQL Performance Analyzer, to help you address performance problems that are not solved by the optimizer.
Oracle strongly recommends that you use those tools rather than hints. Hints should be used sparingly, and only after you have collected statistics on the relevant tables and evaluated the optimizer plan without hints using the EXPLAIN PLAN statement.
