我有以下循环，如果i＆lt; 1可以正常工作，但如果i＆lt; 2则给我以下错误。我不能为我的生活弄清楚它是什么。
我收到此错误：查询失败：您的SQL语法出错;检查与MySQL服务器版本对应的手册，以便在第1行“WHERE 1244790000 - datecreated＆gt; = 432000”附近使用正确的语法实际查询：
这就是循环:(我为这个烂摊子道歉...只编程了几个月而且还没有采用OOP：[...]

答案 0 :(得分：1)
我的猜测是第二次循环，
$ storetbl要么设置为空，要么设置为数据库中不存在的表名。
“DELETE FROM $ storetbl WHERE $ time - datecreated＆gt; = 432000”然后评估为类似
DELETE FROM WHERE $ time - datecreated＆gt; = 432000
尝试一些调试语句或调试器，以确定第二次循环评估$ storetbl的内容。
