問題描述

我正在嘗試將 Rails 連接到 SQL Server.我安裝了 activerecord-sqlserver-adapter 和 ruby??-odbc gems，但我不確定在我的 database.yml 文件中放什么.

I'm trying to connect Rails to SQL Server. I installed the activerecord-sqlserver-adapter and ruby-odbc gems, but I'm not sure what to put in my database.yml file.

到底什么是 DSN，我為什么需要它?(這是一些特定于 Windows 的東西嗎?)

What exactly is a DSN, and why do I need it? (Is this some windows-specific thing?)

如果我想使用 Windows 身份驗證而不是指定用戶名和密碼，該怎么辦?

What do I do if I want to use Windows Authentication, instead of specifying a username and password?

我嘗試創(chuàng)建 DSN，指定 Windows NT 身份驗證，并將以下內(nèi)容放入我的 config.yml:

I tried creating a DSN, specifying Windows NT authentication, and put the following in my config.yml:

development:
  adapter: sqlserver
  dsn: myDsn
  mode: odbc

但我收到指定的 DSN 包含驅(qū)動程序和應(yīng)用程序之間的體系結(jié)構(gòu)不匹配"錯誤.[我也嘗試從 Windows/system32/odbcad32.exe 創(chuàng)建 DSN，因為 Google 搜索說這將創(chuàng)建一個 32 位 DSN，但我得到了同樣的錯誤.]

but I get a "The specified DSN contains an architecture mismatch between the Driver and Application" error. [I tried creating the DSN from Windows/system32/odbcad32.exe as well, since a Google search said this would create a 32-bit DSN instead, but I get the same error.]

我的 database.yml 文件中是否遺漏了什么?

Am I missing something in my database.yml file?

更新:我嘗試使用

development:
  adapter: sqlserver
  mode:odbc
  dsn: Provider=SQLOLEDB; Data Source=.\SQLEXPRESS; Integrated Security=SSPI

但我收到未找到數(shù)據(jù)源名稱且未指定默認(rèn)驅(qū)動程序"錯誤.我的提供程序可能不是 SQLOLEDB 嗎?[我不知道提供程序是什么，也不知道如何確定它應(yīng)該是什么——我只是從我找到的另一個連接字符串中復(fù)制了它.] 我知道我可以使用 Windows 身份驗證從我的計算機連接到 .\SQLEXPRESS實際的 SQL Server Management Studio 程序.

but I get a "Data source name not found and no default driver specified" error. Is it possible my Provider is not SQLOLEDB? [I don't know what a provider is or how to figure out what it's supposed to be -- I just copied it from another connection string I found.] I do know that I can connect to .\SQLEXPRESS using Windows Authentication from my actual SQL Server Management Studio program.

推薦答案

DSN 是數(shù)據(jù)庫源名稱".它包含 ODBC 驅(qū)動程序連接到特定數(shù)據(jù)庫所需的信息.

A DSN is a "Database Source Name." It contains the information that an ODBC driver needs to connect to a specific database.
