Re: Using DBLIB With Azure

I appreciate the offer to help, really.

But I think you are assuming that I have the ability to compile against headers that are not available to me when my native ruby C extensions compiles on a users machine with FreeTDS installed. Now I could really be wrong here and that is specifically what I asked help for. So let me be clear.

I looked thru the FreeTDS code and saw how tsql uses deep internal TDS code to accomplish a default database. If I was making software for my local company or some other thing that I controlled I would dive deep into how tsql does this, write some C, and compile my program against all the non published headers and get what I need.

I on the other hand have a ruby C extension that compiles against publicly available headers for a DBLIB api interface to Sybase/SQLServer. As previously recommended here, my extension compiles against "sybdb.h" and "sybfront.h". So what I am looking for is one of these two things.

1) Is there an API that I am missing to get me what I want because dbuse() is not it.

2) Is there a way that FreeTDS should be working that is not and how can I help contribute to the project by attempting a patch. For example in my last email I stated that it appears that a default database should be pulled from the freetds.conf when you give it a dataserver name. This is not happening and would be one solution if (1) above does not exist. From my perspective, a database pulled from conf may be a bug and again I would try to help with a patch. But maybe somebody will say otherwise for historical reasons why the default database is not being pulled from conf. 

Do you either see what I am saying or am I missing your point? Are you telling me that I should perhaps ship my native C extension with private headers? Are you telling me that in order for me to say TinyTDS can connect to Azure that I tell all my users that have just installed FreeTDS that they need to reinstall it in such a way as to made tds.h available to my C extension when it compiles? Or are you telling me that there is a function in the DBLIB api that I can use? Or maybe that none of the above is valid and that I should explore a patch to FreeTDS that would allow the default database to be pulled from conf? Or something else?
