在上面提到的表中，在代码中插入少量插入查询失败并显示错误

Total Number of diagnostic records: 1 
SQLSTATE: 23000 
Native Error Code: 1022 
[MySQL][ODBC 3.51 Driver][mysqld-5.1.30-community-log]Can't write; duplicate key in table 'd_s_rep'

insert statment“not not”包含id（NOT NULL AUTO_INCREMENT）和t_stamp（NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP）的值。

我在各种论坛上阅读了帖子，但无法解决问题的根本情况。

如果有人可以指导我解决问题

，那将会很有帮助

Answer 1

看起来你正试图设置多个PRIMARY KEY

 PRIMARY KEY (id,f_date)

你只能拥有一个PRIMARY KEY，并且你已经将f_date设置为KEY，所以只需删除，f_date 就可以了。

Answer 2

你可以像下面这样;不要将'f_date'单独声明为

PRIMARY KEY (`id`,`f_date`),
  KEY `d_id` (`d_id`),
  KEY `p_id` (`p_id`), 
  KEY `i_id` (`i_id`),
  KEY `s_id` (`s_id`),
  KEY `t_id` (`t_id`),
  KEY `as_id` (`as_id`)
