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 configu-
       ration 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. :)
