Hi Panos,

Welcome to the FreeTDS project.
The good news is that it should be pretty easy for you to replace Sybase
Db-Library with the FreeTDS version, and connect to SQL Server.
It should be simply a matter of re-compiling your C code, linking in the
FreeTDS libraries instead of the Sybase ones.

I found that the SQL Server help on "sp_dbcmptlevel" was a good guide to
the differences between Sybase & SQL.
Assume that Sybase behaves like SQL Server with compatibility level of
6.5 
Old style *= outer joins are the most work to migrate to SQL Server
compatibility, but there are other subtler issues.
I'm well practiced at these issues, so feel free to use the list if you
have any specific problems.

Bill

Subject: [freetds] DB-library on Unix-Sybase


Hi,

 

I am a beginner with the freeTDS library. I am using the DB-library on
Solaris and connecting to Sybase. I would like to connect to SQL Server
2008. I have a fair amount of code written in C Sybase DB-library. How
easy
will it be to replace my DB-library with the freeTDS version of DB so
that I
can connect to SQL Server instead of Sybase? All my C code is on Unix. I
understand that I will have to convert bits of the C code and recompile
but
how much effort will it be? I hope won't have to change too much.

 

Thank you.

 

Panos.
