NAMEtsql - utility to test FreeTDS connections and queries
SYNOPSIStsql { -S servername [-I interface] | -H hostname -p port }
-U username [-P password] [-o options]
tsql-C
DESCRIPTIONtsql 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 ver‐
sion 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 diagnos‐
tic tool, please recommend them to the FreeTDS mailing list for consid‐
eration.
HISTORYtsql first appeared in FreeTDS 0.60.
