發生原因為 stud_seme_score 資料表未設定  

PRIMARY KEY  (`seme_year_seme`,`student_sn`,`ss_id`),
UNIQUE KEY `sss_id` (`sss_id`)

登入 mysql 處理步驟

0.先刪除重複資料 sfs3/modules/score_input/check_error_0106.php

1.更名  stud_seme_score 為 stud_seme_scor_old

2.  CREATE TABLE IF NOT EXISTS `stud_seme_score` (
  `sss_id` bigint(20) unsigned NOT NULL auto_increment,
  `seme_year_seme` varchar(6) NOT NULL default '',
  `student_sn` int(10) unsigned NOT NULL default '0',
  `ss_id` smallint(5) unsigned NOT NULL default '0',
  `ss_score` decimal(4,2) default NULL,
  `ss_score_memo` text,
  `teacher_sn` smallint(6) NOT NULL default '0',

  PRIMARY KEY  (`seme_year_seme`,`student_sn`,`ss_id`),
  UNIQUE KEY `sss_id` (`sss_id`)
) ENGINE=MyISAM;

3. 還原原先資料INSERT stud_seme_score SELECT * FROM stud_seme_score_old
