Question

我被抛出一个错误：

“SQLSTATE [42000]：语法错误或访问冲突：1064您有 SQL语法错误;查看与您的手册相对应的手册 MySQL服务器版本，用于在'* FROM拍卖附近使用正确的语法在哪里etime＆lt; ？在第1行“

我对此的理解通常是在说错误发生时我拼错了。

但是，在以下脚本中，我的页面的第1行没有"* FROM auction WHERE etime < ?"。

此外，它仅在页面中出现3次 - 在第19,26和288行。

我已经检查了所有这些位置周围的语法错误，看起来很合适。所以我不知道为什么会抛出它，我希望它消失。

页面相当大，请耐心等待：

Answer 1

您的SQL略有偏差，*中有额外的DELETE。提供列列表是没有意义的，因为DELETE总是删除整行;

DELETE * FROM auction WHERE etime < :time

应该是

DELETE FROM auction WHERE etime < :time

Answer 2

我被抛出错误

你不是。

事实上，您正在被抛出更具信息性的错误消息，包括发生错误的确切位置。但由于某种原因，您正在使用删除所有有用信息的代码，向您抛出错误的错误消息。

无法找到来源

如果您get rid of these try and catch operators，您将非常了解发生错误的确切查询。
