    `aname` varchar(30) DEFAULT NULL, 
    `amail` varchar(30) DEFAULT NULL, 
    `anumber` varchar(30) DEFAULT NULL,

您的查詢工作正常，如只要表尚不存在：

CREATE TABLE IF NOT EXISTS `admin` (
      ^^^^^^^^^^^^^ 

您可以通過多種方式，如驗證當前表：

show columns from admin; 
show create table admin; 
select * from admin limit 1; 

您還可以添加一個show warnings;聲明之後的create table一個：

mysql> show warnings; 
+-------+------+------------------------------+ 
| Level | Code | Message      | 
+-------+------+------------------------------+ 
| Note | 1050 | Table 'admin' already exists |
