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 con-
       sideration.

HISTORY
