Modul 6 – Pemrograman PL/SQL: Input/Output Menggunakan Text Box

Oleh: Anis Cherid, M.T.I.

Jika aplikasi berbasis Web yang akan dibuat lebih kompleks sehingga berbagai template yang disediakan tidak lagi mencukupi, Oracle Application Express 10 g juga menyediakan fasilitas

untuk membuat program dengan menggunakan bahasa pemrograman PL/SQL. Sebagaimana bahasa pemrograman yang lain, bahasa pemrograman PL/SQL adalah bahasa pemrograman

yang lengkap. Bahasa PL/SQL memiliki keunggulan dari segi bahwa bahasa pemrograman ini dapat langsung dikombinasikan dengan SQL statement. Bahasa pemrograman PL/SQL untuk

Database Oracle 10 g juga dirancang untuk dapat langsung mengakses berbagai item yang terdapat pada halaman-halaman web aplikasi. Kombinasi antara antarmuka pengembangan

database, antarmuka pembangunan halaman Web, SQL statement dan PL/SQL yang disediakan, menjadikan Oracle Application Express sebagai integrated development environment yang

sangat ideal untuk mengembangkan aplikasi berbasis web yang bersifat database-sentris, dengan sangat cepat dan sangat mudah.

Dalam modul ini akan dibahas aspek input/output dari pemrograman menggunakan PL/SQL. Input dan output yang akan dibahas adalah input dan output menggunakan item di dalam halaman

web. Komponen input dan output yang dipergunakan adalah item yang berjenis text box serta komponen button. Bagaimana kode-kode program PL/SQL dapat berinteraksi dengan berbagai

item tersebut? Temukan jawabannya di dalam modul ini. Selamat mencoba.

Comment: "Buatlah aplikasi baru dengan nama 'Berkenalan dengan PL/SQL' yang terdiri dari sebuah halaman 'blank'."
