An ODBC-only configuration relies solely on odbc.ini for server properties.  Other FreeTDS libraries don't know about odbc.ini.
			
			
Example 4.4. Sample ODBC-only odbc.ini file
[ODBC Data Sources][12] JDBC = Sybase JDBC Server [JDBC] Driver = /usr/local/freetds/lib/libtdsodbc.so Description = Sybase JDBC Server Trace = No Server = jdbc.sybase.com Database = pubs2 Port = 4444 TDS_Version = 5.0 [Default] Driver = /usr/local/freetds/lib/libtdsodbc.so
[12] Several DSNs might be listed here.  In this example, we have only one, “JDBC”.  It matches the [JDBC] entry later in the file.
