Jak vygenerovat balíček API tabulky v Oracle SQL Developer?

V Oracle SQL Developer existuje možnost vygenerovat balíček Table API Package, pomocí kterého můžete snadno spravovat vkládání, aktualizaci a odstraňování pro tabulku. Dále můžete upravit další a přidat požadované změny.

Kroky pro vygenerování balíčku API tabulky v Oracle SQL Developer (verze 18.1)

1. V aplikaci Oracle SQL Developer se připojte k uživateli databáze a na levé straně (panel připojení) rozbalte uzel tabulky.
2. Vyberte tabulku a kliknutím pravým tlačítkem na ni otevřete místní nabídku.
3. Z nabídky vyberte Generovat tabulku API a klikněte na ni.
4. Vygeneruje skript balíčku pro vybranou tabulku a otevře se v editoru SQL na pravé straně.
5. Nyní můžete spustit skript pro vytvoření balíčku ve schématu databáze.

Balíček DML můžete vytvořit online, podívejte se na tento odkaz: Vytvořit balíček DML online

Níže je uveden příklad skriptu balíčku pro rozhraní Table API. Generováno z tabulky Zaměstnanci schématu HR.

Jak používat Table API?

Nyní předpokládejme, že chcete odstranit záznam zaměstnance z tabulky Zaměstnanci, a poté použijte proceduru API balíčku EMPLOYEES_TAPI.DEL takto:

DECLARE 
  P_EMPLOYEE_ID NUMBER;

BEGIN 
  P_EMPLOYEE_ID := 105;

  EMPLOYEES_TAPI.DEL ( P_EMPLOYEE_ID );
  COMMIT; 
END;
