NAME
       tsql - utility to test FreeTDS connections and queries

SYNOPSIS
       tsql   { -S servername [-I interface] | -H hostname -p port }
              -U username [-P password] [-o options]

       tsql   -C

DESCRIPTION
       tsql is a diagnostic tool provided as part of FreeTDS. It uses the TDS
       protocol directly to connect to Sybase or Microsoft SQL Servers, and
       allows the user to issue queries that test the capabilities of FreeTDS.

       tsql is *not* a replacement for a complete isql, such as sqsh
       (www.sqsh.org).  It is designed to rely on the lowest level FreeTDS
       library, tdslib, as a way to isolate potential bugs in the protocol
       implementation.

       tsql can be run in two ways, one which uses the freetds.conf and one
       which connects directly using the server's hostname and port.

       When -S is used, FreeTDS uses the freetds.conf (or equivalent) and
       environment variables in the normal way to determine the server's ip
       address and port. You can use -I to specify a filename, overriding
       FreeTDS's configuration file search algorithm.

       The -H and -p parameters are provided especially for troubleshooting
       new configurations (or servers). Use of these parameters causes FreeTDS
       to ignore any freetds.conf and environment variables.

OPTIONS
       -S servername
              the Database Server to which to connect.

       -I interface
              a freetds.conf or interfaces file describing servername

       -H hostname
              the DNS hostname of the server

       -p port
              the port at which SQL Server is listening

       -U username
              database login name. If username is not provided, a domain login
              is attempted for TDS 7+ connections.

       -P password
              database password.

       -L list server "instances" (with -H)

       -C     prints some of the compile-time configuration parameters.

       -o options
              apply the options specified to every command.

              f      No footer       [result count]

              h      No header       [titles]

              t      Print time

              v      Print version

              q      Quiet

NOTES
       Typing "exit", "quit", or "bye" (or ^D) exits tsql.

       Typing "version" displays the TDS protocol version.

       Command batches may be separated with "go" or "GO". If "GO", the
       version string is reported before executing the batch.

       After prompting for the password, tsql will attempt to connect to the
       remote

       server.
              tsql displays a counter indicating the number of seconds that

       it is attempting to connect.
              Typically, tsql should immediately respond

       with a '1>' prompt.
              If you see the counter (1, 2, 3, ...), most likely tsql is
              unable to connect to the indicated server.

       If you can connect with "tsql -S servername", your basic FreeTDS
       installation is working.

       If you have suggestions for ways to make tsql more useful as a
       diagnostic tool, please recommend them to the FreeTDS mailing list for
       consideration.

HISTORY
       tsql first appeared in FreeTDS 0.60.

AUTHORS
       The tsql utility was written by Brian Bruns.

BUGS
       Several, to be sure, now that it's documented. :)
