Zurückgeben des Werts der Identitätsspalte nach dem Einfügen in Oracle

Verwenden Sie einfach den RETURNING Klausel.

Zum Beispiel -

RETURNING identity_id INTO variable_id;

Testfall -

SQL> set serveroutput on
SQL> CREATE TABLE t
  2    (ID NUMBER GENERATED ALWAYS AS IDENTITY, text VARCHAR2(50)
  3    );

Table created.

SQL>
SQL> DECLARE
  2    var_id NUMBER;
  3  BEGIN
  4    INSERT INTO t
  5      (text
  6      ) VALUES
  7      ('test'
  8      ) RETURNING ID INTO var_id;
  9    DBMS_OUTPUT.PUT_LINE('ID returned is = '||var_id);
 10  END;
 11  /
ID returned is = 1
