MySQL的：错误在表1022复制的钥匙

在上述表较少插入fronm插入查询中代码失败，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' 

插入statment“不”包括用于ID（NOT NULL AUTO_INCREMENT）和t_stamp值（NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP）。

我在各种论坛上阅读帖子，但无法得到问题的根本原因。

这将是巨大的帮助，如果有一个人能指导我解决问题

Answer 1

它看起来像你想设置一个以上的PRIMARY KEY

PRIMARY KEY (id,f_date) 

只能有一个主键并且你已经将f_date设置为KEY，所以只需擦除，f_date，你应该没问题。

Answer 2

你可以像下面这样;不要单独声明'f_date'作为密钥

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`)
