tsql

NAME

tsql - utility to test FreeTDS connections and queries

SYNOPSIS

tsql

{ -S servername [-I inside] | -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 inside

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.

-P password

database password.

-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. 
 

 
 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.

 tsql first appeared in FreeTDS 0.60.
