问题
I need to write an iPhone application to connect an instance of SQL Server but I can't figure out which framework I could use to do this. Is there an ODBC framework I could use? Any links would be appreciated.
Please do not tell me to use a web service as that won't fit for this situation.
EDIT: I'm building a SQL querying tool for the iPhone. I don't want my users to have to setup a web service if they just want to query a couple tables in their database.

As you're undoubtably away, choices for connecting to SQL Server in Objective-C are quite limited. Here are a few options:
- MacSQL ($699)
- Commercial product
- Designed for OS X - no word on iOS compatability
- ODBC Router ($799)
- Another commercial product
- Appears to funnel requests through a server running special software
- iSql ($25)
- Commercial
- Relaies on .Net web service, which can be hosted along side SQL Server database, to act as intermediary
Alternatively, since Objective-C is a superset of C, vanilla C works just fine, though you won't get the inherent "niceness" of working with an OO library. Microsoft has a page on ODBC Programmer's Reference to get you started.
