Pengenalan Operator Logika Pada MySQL

Pada tutorial kali ini, kita akan belajar tentang macam-macam operator logika pada MySQL beserta contohnya.

Macam-Macam Operator Logika

Berikut ini adalah tabel macam-macam operator logika yang terdapat pada MySQL:

Operator	Deskripsi
AND	Menggunakan logika AND didalam WHERE clause
OR	Menggunakan logika OR didalam WHERE clause
IN	Akan membandingkan data dengan list yang telah ditentukan

LIKE	Membandingkan data yang sesuai dengan pola tertentu (wildcard)
IS NULL	Membandingkan apakah data sama dengan null?
