有用的库存 SQL 数据集? [英] Useful stock SQL datasets?
问题描述
有没有人知道有什么资源可以提供好的、有用的股票数据集?例如,我下载了一个包含美国所有州、城市和邮政编码的 SQL 脚本.这为我在最近的一个应用程序中节省了很多时间,我希望能够按地理位置进行查找.你们中有人知道其他可以免费下载的有用数据集吗?
Does anyone know of any resources that provide good, useful stock datasets? For example, I've downloaded a SQL script that includes all of the U.S. states, cities, and zipcodes. This saved me a lot of time in a recent application where I wanted to be able to do lookups by geography. Are any of you aware of other useful datasets that are freely available for download?
例如:
- 列入黑名单的 IP 地址
- 学院/大学名称
- 公司名称/股票代码
有人有什么建议吗?
作为一个例子,我在这里找到了一个 MySQL 脚本,其中包含所有美国邮政编码及其对应的纬度/经度.有没有其他人在 SQL 中找到了类似有用的数据集,可以轻松导入和使用?
As an example, here is the location where I found a MySQL script containing all of the U.S. zip codes and their corresponding latitude/longitude. Has anyone else found similarly useful datasets in SQL that can be easily imported and used?

为了澄清我在谈论什么类型的数据集...我指的是可以立即对应用程序有用的数据集,可以应用于各种场景,并且通常代表易于查找的信息小案例,但更难为更大的数据集编译.邮政编码数据库对我来说就是一个很好的例子.获取单个给定邮政编码的纬度/经度并不难.但是,获取美国所有有效邮政编码的值会花费一些时间.这些数据对单个行业或商业部门也没有用处,但可以应用于一系列应用.
To clarify what type of datasets I'm talking about... I'm referring to datasets that can be immediately useful for applications, can be applied across a variety of scenarios, and typically represent information that is easy to find for small cases but harder to compile for larger data sets. The zip code database is a great example to me. It's not hard to get the lat/long for a single given zip code. But, it's a bit more time consuming to get the values for all valid zip codes in the U.S. This data is also not useful to a single industry or business sector, but can be applied across a range of applications.
推荐答案
这里有很多打开数据集的链接:
Lots of links to open data sets here:

虽然我怀疑它们中的任何一个都会为你生成 SQL 语句.
although I doubt any of them will generate SQL statements for you.
