HDC调试需求开发（15万预算）,能者速来！>>> 最近遇到一个奇怪的问题。 在SQLite的一个数据表中，START和FINISH两个字段都是INTEGER类型，而且这两个字段都创建了索引，ASC排序。之前一直都是正常的，今天出现下面的情况。 问题1：图中查询结果的START第一个值1586693177很明显比查询条件1587052800小，竟然也能查询出来； 问题2：如果把图中的查询语句FINISH条件放出来，则无法查询出任何记录，事实上库表中有符合条件的数据； 问题3：如果把START和FINISH两个字段的索引删除，再执行上述查询，则一切正常。 实在搞不懂什么情况了，希望有熟悉SQLite的大佬指点，提前谢过。
