utility to test FreeTDS connections and queries

osql
is a diagnostic tool provided as part of FreeTDS.
It is a Bourne shell script that checks and reports on your configuration
files. If everything checks out OK, it invokes isql.
osql
works only with the isql that comes
with unixODBC.
-S
dsn
- the Data Source Name to which to connect, as known to
odbc.ini.
-U
username
- database login name.
-P
password
- database password.
-I
ini_dir
- override odbc.ini file location.
If you have an odbc.ini with a section like this:
[myDSN
]
servername = myserver
TDS_Version = 5.0
You would invoke osql
as:
osql -S myDSN
[...]
If you can connect with ‘osql -S servername -U user -P
passwd
’,your FreeTDS ODBC installation is working.
osql
guesses where unixODBC might look for
its odbc.ini by examining the binary. This is not
always an effective approach. If it doesn't work, you'll receive a report of
candidate strings. Kindly pass along the output to help improve the
guessing.
If osql
cannot intuit your
odbc.ini directory, you can force the issue with the
-I
option. However, you're then instructing
osql
what to test, not where unixODBC will
eventually look. Your override is therefore only as good as you are. Look
carefully at the error output before overriding.
If you have suggestions for ways to make
osql
more useful as a diagnostic tool, please post
them to the FreeTDS mailing list.
osql
first appeared in FreeTDS 0.65.
