Hvordan genereres tabel API-pakke i Oracle SQL Developer?

I Oracle SQL Developer er der mulighed for at generere en Table API-pakke, som du nemt kan administrere indsættelse, opdatering og sletning af en tabel med. Yderligere kan du ændre flere for at tilføje dine nødvendige ændringer.

Trin til at generere en tabel API-pakke i Oracle SQL Developer (version 18.1)

1. I Oracle SQL Developer skal du oprette forbindelse til databasebrugeren og i venstre side (forbindelsespanel) udvide tabelnoden.
2. Vælg tabellen, og højreklik på den for at åbne genvejsmenuen.
3. Vælg Generer tabel API i menuen og klik på den.
4. Det genererer pakkescriptet for den valgte tabel og åbner i højre side af SQL-editoren.
5. Nu kan du udføre scriptet for at oprette pakken i dit databaseskema.

Nedenfor er et eksempel på et pakkescript til Table API. Genereret fra HR-skemaets medarbejdertabel.

Hvordan bruger man Table API?

Antag nu, at du vil slette en medarbejderpost fra tabellen Medarbejdere, og brug derefter pakke-API-proceduren EMPLOYEES_TAPI.DEL som følger:

DECLARE 
  P_EMPLOYEE_ID NUMBER;

BEGIN 
  P_EMPLOYEE_ID := 105;

  EMPLOYEES_TAPI.DEL ( P_EMPLOYEE_ID );
  COMMIT; 
END;
