NAME

     freetds.conf -- configuration file for FreeTDS

SYNOPSIS

     The freetds.conf file describes Sybase and Microsoft database servers to
     the FreeTDS library.  It comprises sections headed by a servername,
     followed by a list of connection properties denoted as name-value pairs.
     Defaults are defined via a [global] section.  This file supersedes the
     interfaces file that Sybase defines for the same purpose, although the
     latter is still supported.

DESCRIPTION

     A section begins with a servername -- the name of the server -- in square
     brackets. The servername is chosen at the client's descretion.  (One
     exception: with Sybase ASA the servername must match the database name to
     be used.)

     Sections contain properties, one per line, in the form

           name = value

     where name is the connection property to be described.  Servernames and
     properties are not case sensitive.  Values are case-preserving i.e.,
     copied literally.  Comments begin with either a semicolon (';') or pound
     sign ('#') and continue to end of line.  Blank lines are ignored.
     Whitespace surrounding the '=' is ignored.

   DEBUG FLAGS
     The log's granularity can be controlled with the debug flags property.

NAMES AND LOCATIONS

     The file is normally named /etc/freetds.conf or ${HOME}/.freetds.conf.
     That name can be overridden with the FREETDSCONF environment variable.

     FreeTDS will search conf files for a servername in the following order:
           1.   a filename set programatically via dbsetifile() that is in
                .conf format
           2.   a filename in the environment variable FREETDSCONF that is in
                .conf format
           3.   ${HOME}/.freetds.conf if extant
           4.   @sysconfdir@/freetds.conf

     The search stops with the first file containing the servername.

     If no conf file is found, FreeTDS searches for an interfaces file in the
     following order:
           1.   a filename set programatically via dbsetifile() that is in
                interfaces format
           2.   ${HOME}/.interfaces
           3.   $SYBASE/interfaces (where $SYBASE is an environment variable)

     If the requested servername is not found in any configuration file, the
     fallback mechanism is:
           1.   attempt to convert the name to an IP address with
                inet_addr(3), else
           2.   attempt to convert the name to an IP address with
                gethostbyname(3), else
           3.   attempt to look up the literal name ``SYBASE''

ENVIRONMENT

     FREETDSCONF    overrides name and location of the system-wide conf file
     TDSDUMP        overrides the name and location of the FreeTDS log file
     TDSDUMPCONFIG  specifies a name and location of a file that logs the
                    search of configuration files
     TDSHOST        overrides the host property
     TDSPORT        overrides the port property
     TDSQUERY       synonym for DSQUERY, the default servername
     TDSVER         overrides the version specified in the freetds.conf

     The environment variables TDSVER, TDSDUMP, TDSPORT, TDSQUERY, and TDSHOST
     override values set by a .conf or interfaces file.

FILES

     @sysconfdir@/freetds.conf, ${HOME}/.freetds.conf
