出了什么问题？

在你写的时候结束了数据。各地的数据都是一样的。错误在不同的行上随机出现。以下是您编写输出的示例：

这是最后两个结论，最后，你可以看到有一个错误。

要解决此问题，第一步应该是打印出所有直接值，这样您就可以验证它们是否符合您的想法。作为副作用，这使您的select语句更容易阅读。

例如：

selection = WinRedactor.Table.selection()
print("selection is", selection)
first_selection = selection[0]
print("first selection is", first_selection)
values = WinRedactor.Table.item(first_selection, option='values')
print("values are", values)
checksum = values[3]
print("checksum:", checksum)

CurFiles.execute('SELECT * FROM Files WHERE CheckSum = ?', (checksum,))

我的猜测是，你会对你看到的内容感到惊讶。至少，您有更多的数据要放入您的问题，以便我们准确地知道数据是什么。
