I have a DB table that is myISAM, used for fulltext searching. 我有一个数据库表是myISAM，用于全文搜索。 I also have a table that is InnoDB. 我还有一张InnoDB表。 I have a column in my myISAM table that I want to match with a column in my InnoDB table. 我的myISAM表中有一列我希望与InnoDB表中的列匹配。 Can that be done? 可以这样做吗？ I cant seem to work it out! 我似乎无法解决它！

Foreign keys definitions are subject to the following conditions: 外键定义符合以下条件：

Both tables must be InnoDB tables and they must not be TEMPORARY tables. 两个表都必须是InnoDB表，它们不能是TEMPORARY表。

So, I'm afraid you wont be able to achieve what you want done. 所以，我担心你无法达到你想要的目标。

I would recommend altering your DB architecture such that you have one set of tables designed with data integrity for writing (all InnoDB), and a second set designed for search - possibly on a different box, and possibly not even using MySQL, but maybe a search server like Solr or Sphinx, which should outperform a fulltext MySQL table. 我建议改变你的数据库架构，使你有一组设计有数据完整性的表（所有InnoDB），第二组设计用于搜索 - 可能在不同的盒子上，甚至可能不使用MySQL，但也许是搜索服务器，如Solr或Sphinx，它应该胜过全文MySQL表。 You could then populate your search DB periodically from your write DB. 然后，您可以定期从写入数据库填充搜索数据库。
