Unfortunately, no. The only place to put named instance information is
However, you put a good idea in my head. A little googolocity turned up
http://support.microsoft.com/kb/260418/en-us (see #6)
I think the next release should support named instances in, er, the
name. Just because Microsoft wants you to use MDAC 2.6 doesn't mean we
can't enhance db-lib.
I propose a named instance have the form:
e.g. dbopen(login, "servername\instance");
(where the leading backslashes are optional), similar to the form:
for domain logins.
If we put this in src/tds/login.c, it should work for all libraries.
Done correctly, users would never have to specify a port (or even a
server!) for a normal TDS 7.0+ connection. The logic would be:
1. Use instance if specified in connection string, else
2. Use instance/port if provided in freetds.conf, else
3. Use port 1433.
