OSQL(FreeTDS) FreeTDS Reference Manual OSQL(FreeTDS)NAMEosql — utility to test FreeTDS connections and queries
SYNOPSISosql-S dsn -U username -P password [-I ini_directory]
DESCRIPTIONosql 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.
OPTIONS-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.
EXAMPLE
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 [...]
FILES
odbc.ini freetds.conf
NOTES
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 out‐
put 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.
HISTORYosql first appeared in FreeTDS 0.65.
