How do i add 0 in database for telephone number

Question

所以我想将 0 放入我的电话列数据库中，我尝试使用此代码，但它不断收到错误消息，表示意外的“0”，对于该列，我使用的是 int

  mysqli_query($koneksi,"INSERT INTO distributor VALUES('','$nama_distributor','$alamat','"0".$telpon')");

Answer 1

use concat() function

mysqli_query($koneksi,"INSERT INTO distributor 
 VALUES('','$nama_distributor','$alamat',concat('0','$telpon'))");

Answer 2

You have to mentions the column names like this and use the cast() function

Declare @Num1 int
set @Num1 = 0

 mysqli_query($koneksi,"INSERT INTO distributor (column1, column2, column3, column4) VALUES('','$nama_distributor','$alamat', cast(@Num1 as varchar() + $telephone as varchar(12)");
