| | | gak boleh kosong |
| | | maksudnya field yang diisikan tidak boleh kosong yaa biar bisa diproses....? |
| | | yaaap |
| | | ok terima kasih buat jawabannya, heheheheh. MERDEKA....! :P |
| | | Null ""
Nol "0"
Not null "hehe" |
| | | NULL = Empty; artinya dia tidak bernilai, meski hanya "" atau '' atau 0. Secara sederhana ia hampa, kosong, tiada. *sok puitis.com :P. NOT NULL ya berarti selain deskripsi diatas ^_^... Artinya ia harus punya nilai meski berupa string kosong ditandai dengan "" atau '', atau angka 0. |
| | | tidak kosong......tetapi bukan mutlak int 0 atau string 0 |
| | | Kebalikannya null, biasanya buat primary key. | |  |
