有时候正常有时候报错。真的很头疼。搞了一个星期没弄好。找大侠帮个忙 --------------------编程问答-------------------- 在线等待！跪求大侠帮忙 --------------------编程问答-------------------- 这没人能帮你，都说了是索引超范围，那就检查所有访问索引的地方吧 --------------------编程问答-------------------- 本地调试一点也没问题。就是网站访问高峰期时有一少部分用户会报这个错误 --------------------编程问答--------------------
索引超出范围 自己看循环的地方吧，这玩意儿确实没人能帮你
你这代码看着也头疼 --------------------编程问答-------------------- 帅哥，你拼得不累啊这么搞，我看着就头晕啊。你只查询了5个字段，却要读取10（0~9）个字段，索引不超出才怪咧 --------------------编程问答--------------------
--------------------编程问答--------------------
SQL查询语句用参数啊。你的这个代码用代码块贴出来，直接这样上文本，谁看着都会累的。
看问题的情况，貌似楼主要自己解决了。 --------------------编程问答-------------------- 索引超出范围: list[i]这里超出了。你再详细看看哦。
