  2. Pendahuluan • Definisi • Tipe data bentukan yang dapat menyimpan sekumpulan nilai dari tipe data yang sama dan dikemas dalam bentuk larik. • Nilai dari elemen-elemen array dapat diacu atau diakses melalui indeksnya, perlu diperhatikan bahwa indeks array harus dari tipe data yang mempunyai keterurutan, seperti halnya tipe integer.

  3. Membuat Tipe Array • Bentuk Umum : TYPE nama_tipe IS TABLE OF tipe_data INDEX BY BINARY_INTEGER; • Contoh : DECLARE TYPE array_ku IS TABLE OF CHAR(5) INDEX BY BINARY_INTEGER; X array_ku;

  4. Mengisikan Nilai pada Elemen Array • Contoh 1 : BEGIN X(1) := ‘A’; X(2) := ‘B’; END; • Contoh 2 : BEGIN X(1) := 10; X(2) := 20; END;

  5. Contoh 1 SET SERVEROUTPUT ON DECLARE TYPE LARIK IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; A LARIK; I INTEGER; BEGIN FOR I IN 1..5 LOOP A(I) := I * 10; END LOOP; FOR I IN 1..5 LOOP DBMS_OUTPUT.PUT_LINE(‘Nilai elemen larik ke-’ || TO_CHAR(I) || ‘ = ‘ || TO_CHAR(A(I))); END LOOP; END; /

  6. Contoh 2 SET SERVEROUTPUT ON DECLARE TYPE SISWA IS TABLE OF VARCHAR2(25) INDEX BY BINARY_INTEGER; NAMA SISWA; I INTEGER; BEGIN NAMA(1) := ‘Arista Destriana’; NAMA(2) := ‘Yandri Gunawan’; NAMA(3) := ‘Herry Wahyudinata’; NAMA(4) := ‘Budi Raharjo’; NAMA(5) := ‘Noni Sutrisna’; FOR I IN 1..5 LOOP DBMS_OUTPUT.PUT_LINE(‘Nama siswa ke-’ || TO_CHAR(I) || ‘ : ‘ || NAMA(I)); END LOOP; END; /
