MySQL截断我的第一个零数据

Question

I have a MySQL column "phone" , and when data comes from my php form, if there's a zero at the beginning, it will disappear in the table, for example : " 06719823 " becomes " 6719823 "

I first though it was a problem from php, cause I'm using mysql_real_escape_string(), but then I tried to modify the SQL field directly on phpmyadmin, and I can't add a first 0, it always delete it.

Colonne     Type     Interclassement    Attributs   Null    Défaut  Extra
phone       int(10)                                 Oui     NULL    

What's wrong ? Should I assign an "interclassement" utf8_general_ci ?

Answer 1

将10位电话号码的列类型更改为char(10) 。

Answer 2

If the column type is int (integer), the number will be internally represented as an integer , meaning "first 0s" won't be stored, as they hold no meaning for integers.

Since what you are actually trying to store has meaning as a sequence of characters , and not as a quantity, it would make more sense to store it as a char(n) , for n-digit sequences, or as a varchar for sequences whose size varies a lot.

Answer 3

Make your phone attribute as Varchar or Text to avoid this.

Phone numbers can at time also contain brackets and hyphens plus you can avoid your problem as well.

Answer 4

Change your data type. Int Data type will not store the starting 0's.

You can try as suggested above char or varchar

Answer 5

Integers : 06719823 = 6719823 = 0006719823

如果您想在开头保留零，请将手机另存为varchar
