Cara memasukkan tanggal di mysql dalam format dd/mm/yyyy

Masalah ini menjelaskan format tanggal untuk memasukkan tanggal ke dalam database MySQL. MySQL mengambil dan menampilkan nilai DATETIME di 'YYYY-MM-DD HH. MM. format SS. Tanggal hanya dapat disimpan dalam format ini. Namun, ini dapat digunakan dengan fungsi format waktu apa saja untuk mengubahnya dan menampilkannya

Saat menulis kueri di MySQL menggunakan PHP, penerapannya akan diperiksa berdasarkan MySQL itu sendiri. Jadi gunakan format tanggal dan waktu default seperti yang disediakan oleh MySQL i. e. 'YYYY-MM-DD'

Contoh

DATE: YYYY-MM-DD
Example: 2005-12-26

DATETIME: YYYY-MM-DD HH:MI:SS
Example: 2005-12-26 23:50:30

TIMESTAMP: YYYY-MM-DD HH:MI:SS
Example: 2005-12-26 23:50:30

YEAR: YYYY or YY

Contoh 3. Contoh ini digunakan untuk menampilkan baris mana yang dibuat pada 05-12-2018. Gunakan kueri berikut untuk menampilkan hasil
Kolom create_at tidak hanya berisi tanggal tetapi juga waktu. Sehingga akan muncul pesan error

SELECT * FROM date_test WHERE created_at = '2018-12-05';

Keluaran

(!Important) Wrong Query It returns no rows

Kueri yang Benar. Untuk memperbaikinya, gunakan fungsi DATE sebagai berikut

SELECT * FROM date_test WHERE DATE( created_at ) = '2018-12-05';

Untuk mendapatkan tahun, kuartal, bulan, minggu, hari, jam, menit, dan detik dari nilai DATETIME, gunakan fungsi seperti yang ditunjukkan pada pernyataan berikut
JAM(@dt), MENIT(@dt), DETIK(@dt), HARI(@dt), MINGGU(@dt), BULAN(@dt), KUARTAL(@dt), TAHUN(@dt);
