First time poster here, so be gentle... I am completely stuck, I have been given the task of importing some old.DTA files into tables in SSMS so we can run queries off of them.第一次在这里发帖，所以要温柔……我完全被困住了，我被赋予了将一些 old.DTA 文件导入 SSMS 表中的任务，以便我们可以对它们运行查询。 Being brand new to.dta formats, I did some digging and this is the information I was able to gather up so far:作为全新的 to.dta 格式，我进行了一些挖掘，这是迄今为止我能够收集到的信息：

.DTA files are data files generated by Btrieve software, which Btrieve then had a name change to PervasiveSQL, which is now owned by Actian .DTA 文件是由 Btrieve 软件生成的数据文件，然后 Btrieve 将名称更改为 PervasiveSQL，现在归 Actian 所有
.DTA files have accompanying system catalog DDF files (data definition files) .DTA 文件具有随附的系统目录 DDF 文件（数据定义文件）
According to this post https://www.tek-tips.com/viewthread.cfm?qid=364542 I should be able to download the PervasiveSQL demo to be able to explore these DTA files but now I am taken to the Actian website when I click on the links provided.根据这篇文章https://www.tek-tips.com/viewthread.cfm?qid=364542我应该能够下载 PervasiveSQL 演示以便能够探索这些 DTA 文件但现在我被带到了 Actian 网站我点击提供的链接。
We do not have access to the front end software anymore我们无法再访问前端软件

When I go to the Actian website, its asking me for a username and password to be able to download any trial software.当我 go 访问 Actian 网站时，它要求我输入用户名和密码才能下载任何试用软件。
Before I go signing up for anything, I wanted to check in with you smart people to see if you know of any alternatives to extracting the data out of these legacy.DTA files so I am able to populate it into SQL tables.在我 go 注册任何东西之前，我想与各位聪明人联系，看看您是否知道从这些 legacy.DTA 文件中提取数据的任何替代方法，以便我能够将其填充到 SQL 表中。 BTW, I have tried all of the obvious;顺便说一句，我已经尝试了所有显而易见的方法； exploring in notepad, excel, access, using any/all drivers in SSMS for importing data/openrowset and even trying to use an ODBC driver for Btrieve and none of those have given me any success.在记事本中探索，excel，访问，使用 SSMS 中的任何/所有驱动程序来导入数据/openrowset，甚至尝试为 Btrieve 使用 ODBC 驱动程序，但这些都没有给我任何成功。
I would just LOVE it if there was something obvious I am missing or if anyone has had any success using the Actian software.如果有明显的我遗漏的东西，或者如果有人使用 Actian 软件取得了任何成功，我会喜欢它。

Thanks in advance!提前致谢！

You must have an engine that can read the DTA files.您必须有一个可以读取 DTA 文件的引擎。 If you have the DDFs that match the DTA files and the engine that can read them, you can create an ODBC DSN because the engine includes ODBC drivers.如果您有与 DTA 文件匹配的 DDF 和可以读取它们的引擎，则可以创建 ODBC DSN，因为引擎包含 ODBC 驱动程序。 Once you have the ODBC DSN, you can use SSMS, Access, Excel, or any other ODBC tool to access the files.拥有 ODBC DSN 后，您可以使用 SSMS、Access、Excel 或任何其他 ODBC 工具来访问文件。

I would recommend downloading the Zen Workgroup engine v14 Trial for Windows x86 32/64-bit from the Actian website (as of Sept 2019).我建议从 Actian 网站下载 Zen Workgroup engine v14 Trial for Windows x86 32/64 位（截至 2019 年 9 月）。 It is the current version and should be sufficient for a one time (or after purchasing a license, multiple time) import.它是当前版本，一次（或购买许可证后，多次）导入应该足够了。
