Hoe een Table API-pakket te genereren in Oracle SQL Developer?

In Oracle SQL Developer is er een optie om een ​​Table API Package te genereren waarmee u eenvoudig het invoegen, bijwerken en verwijderen van een tabel kunt beheren. Verder kunt u meer wijzigen om uw gewenste wijzigingen toe te voegen.

Stappen om een ​​Table API-pakket te genereren in Oracle SQL Developer (versie 18.1)

1. Maak in Oracle SQL Developer verbinding met de databasegebruiker en vouw aan de linkerkant (verbindingspaneel) het tabelknooppunt uit.
2. Selecteer de tafel en klik er met de rechtermuisknop op om het snelmenu te openen.
3. Selecteer in het menu de Generate Table API optie en klik erop.
4. Het genereert het pakketscript voor de geselecteerde tabel en wordt geopend in de SQL-editor aan de rechterkant.
5. Nu kunt u het script uitvoeren om het pakket in uw databaseschema te maken.

U kunt het DML-pakket online maken via deze link: Online DML-pakket maken

Hieronder ziet u een voorbeeldpakketscript voor Table API. Gegenereerd uit de werknemertabel van het HR-schema.

Hoe de Table-API gebruiken?

Stel nu dat u een werknemersrecord uit de tabel Werknemers wilt verwijderen, gebruik dan de pakket-API-procedure EMPLOYEES_TAPI.DEL als volgt:

DECLARE 
  P_EMPLOYEE_ID NUMBER;

BEGIN 
  P_EMPLOYEE_ID := 105;

  EMPLOYEES_TAPI.DEL ( P_EMPLOYEE_ID );
  COMMIT; 
END;
