12 tsql is a FreeTDS diagnostic tool. It uses the TDS protocol to connect to
13 a Sybase or Microsoft SQL Server, and lets the user issue queries. tsql
14 does not use the FreeTDS client libraries. Instead, it uses only the low‐
15 est level library, libtds, to test the protocol implementation.
16
17 tsql can be run in two ways, one which uses the freetds.conf and one
18 which connects directly using the server's hostname and port. The -H and
19 -p parameters are provided to let the user verify a server is listening
20 on the named host and port. These parameters override any configuration
21 files and environment variables. The -S parameter can be used to test
22 the local configuration. FreeTDS will use freetds.conf (or equivalent)
23 and environment variables in the normal way to determine the server's IP
24 address and port. You can use -I to specify a filename, overriding
25 FreeTDS's configuration file search algorithm.
26
28 -S servername
29 database server to which to connect.
30
31 -D dbname
32 database to use.
33
34 -I interface
35 freetds.conf or interfaces file describing servername.
36
37 -H hostname
38 DNS hostname of the server.
39
40 -p port
41 port at which SQL Server is listening.
42
43 -U username
44 database login name. If username is not provided, a domain login
45 is attempted for TDS 7+ connections.
46
47 -P password
48 database password.
49
50 -L list Microsoft server instances (with -H).
51
52 -C print some of the compile-time configuration parameters.
53
54 -o options
55 apply the options specified to every command.
56
57 -f No footer [result count]
58
59 -h No header [titles]
60
61 -t Print time
62
63 -v Print version
64
65 -q Quiet
66
67 -a appname
68 application name.
69
70 -t colterm
71 column terminator.
72
73 -r rowterm
74 row terminator.
75
76 -r rowterm
77 row terminator.
78
79 -J charset
80 character set.
81
82 -v verbose mode.
83
85 If you can connect with ‘tsql -S servername’, your basic FreeTDS instal‐
86 lation is working.
87
88 Typing ‘exit’, ‘quit’, or ‘bye’ (or ^D) exits tsql.
89
90 Typing ‘version’ displays the TDS protocol version.
91
92 Command batches may be separated with ‘go’ or ‘GO’. If ‘GO’ the version
93 string is reported before executing the batch.
94
95 After prompting for the password (if not provided with -P), tsql will at‐
96 tempt to connect to the remote server. tsql displays a counter indicat‐
97 ing the number of seconds elapsed during the connection attempt. Typi‐
98 cally, tsql immediately responds with a ‘1>’ prompt. If you see the
99 counter (1, 2, 3, ...), most likely tsql is unable to connect to the in‐
100 dicated server.
101
102 tsql is not a replacement for a complete isql such as sqsh
103 (www.sqsh.org). If you have suggestions for ways to make tsql more use‐
104 ful as a diagnostic tool, please post them to the FreeTDS mailing list
105 for consideration.
106
108 tsql first appeared in FreeTDS 0.60.

111 The tsql utility was written by Brian Bruns.

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