Hur man genererar tabell API-paket i Oracle SQL Developer?

I Oracle SQL Developer finns det ett alternativ att generera ett Table API-paket med vilket du enkelt kan hantera infoga, uppdatera och ta bort för en tabell. Vidare kan du ändra mer för att lägga till dina nödvändiga ändringar.

Steg för att generera ett tabell-API-paket i Oracle SQL Developer (version 18.1)

1. I Oracle SQL Developer, anslut till databasanvändaren och expandera tabellnoden på vänster sida (anslutningspanelen).
2. Välj tabellen och högerklicka på den för att öppna genvägsmenyn.
3. Välj Generera tabell-API på menyn alternativet och klicka på det.
4. Det kommer att generera paketskriptet för den valda tabellen och öppnas i SQL-redigerarens högra sida.
5. Nu kan du köra skriptet för att skapa paketet i ditt databasschema.

Du kan skapa DML-paketet online, kolla den här länken: Skapa DML-paket online

Nedan finns ett exempel på paketskript för Table API. Genereras från HR-schemats Employee-tabell.

Hur använder man Table API?

Anta nu att du vill ta bort en anställd post från tabellen Anställda, använd sedan paketets API-procedure EMPLOYEES_TAPI.DEL enligt följande:

DECLARE 
  P_EMPLOYEE_ID NUMBER;

BEGIN 
  P_EMPLOYEE_ID := 105;

  EMPLOYEES_TAPI.DEL ( P_EMPLOYEE_ID );
  COMMIT; 
END;
