MySQL 错误 #1054

Question

将数据上传到 mysql 时出现此错误:

#1054 - Unknown column 'aid' in 'field list' "

这是我收到错误 #1054 的部分

CREATE TABLE IF NOT EXISTS `admin` (
  `aid` int(11) NOT NULL AUTO_INCREMENT,
  `aname` varchar(30) DEFAULT NULL,
  `amail` varchar(30) DEFAULT NULL,
  `anumber` varchar(30) DEFAULT NULL,
  `aip` varchar(30) DEFAULT NULL,
  `apass` varchar(50) DEFAULT NULL,
  `atime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `city` varchar(30) NOT NULL,
  `fb` varchar(100) NOT NULL,
  `other` varchar(100) NOT NULL,
  PRIMARY KEY (`aid`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;

-- Dumping data for table `admin`

INSERT INTO `admin` (`aid`, `aname`, `amail`, `anumber`, `aip`, `apass`, `atime`, `city`, `fb`, `other`) VALUES
(1, 'M SaeeD KhaN NiaZi', 'mianwali@gmail.com', '03437517173', '::1', 'niazi', '2015-07-14 23:00:00', 'MiAnWaLi  PAKisTaN', 'www.facebook.com', 'BhAnGi  BhAi');

只要该表尚不存在，您的查询就可以正常工作:

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

您可以通过多种方式验证当前表，例如:

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

您还可以在 create table 语句之后添加一个 show warnings; 语句:

mysql> show warnings;
