Question

尝试插入MS SQL数据库，但我对此错误感到震惊：

INSERT语句与FOREIGN KEY约束冲突

原始错误（德语）

pypyodbc.IntegrityError: (u'23000', u'[23000] [Microsoft][ODBC SQL Server Driver][SQL Server]Die INSERT-Anweisung steht in Konflikt mit der FOREIGN KEY-Einschr\xe4nkung "FK_tCompanyLocation_tCompany". Der Konflikt trat in der Test-Datenbank, Tabelle "dbo.tCompany", column \'GUID\' auf.')

现在....我想我得到了错误...在插入tCompanyLocation时，company_guid（GUID）将不在tCompany表中，因为它将作为第二个插入我的脚本中。但是tCompany还需要company_location_guid（LocationGUID），所以我不能在之前执行....

在我看来，这就像鸡肉和鸡肉一样。 egg problem ...由于tCompanyLocation，我无法插入tCompany，反之亦然。

问题：

如何解决这个问题？我知道从Python生成GUID很糟糕，但是如果不在Python中实现它，我怎么能实现呢？如果有人可以告诉我，如何插入这两张表，那就太棒了。
