错误代码1062 SQL

Question

I'm getting the error

code 1062 in the INSERT code below (for the table 'Tech').

Any help would be greatly appreciated!

CREATE TABLE IF NOT EXISTS `Tech` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `name` varchar(255) NOT NULL,
  PRIMARY KEY  (`id`),
  FOREIGN KEY (id) REFERENCES AppliedTech(id_questions)
) ENGINE=InnoDB   DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

INSERT INTO `Tech` (`id`, `name`) VALUES
(1, 'Applied Tech'),
(2, 'Communications Equipment'),
(3, 'Computer Systems'),
(4, 'Internet/Digital Media'),
(5, 'Semiconductors'),
(6, 'IT Services'),
(7, 'Payments Processing'),
(8, 'Software');

Answer 1

看来您面对另一个表AppliedTech中的重复键

Answer 2

The table Tech already exists and has data. CREATE TABLE IF NOT EXISTS don't re-create table and in insert you have duplicate key violation.
