NAME¶
osql - utility to test FreeTDS connections and queries 
SYNOPSIS¶
osql  -S dsn -U username -P password [-I ini_dir]
DESCRIPTION¶
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.
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 [...]
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 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 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.
HISTORY¶
osql first appeared in FreeTDS 0.65.
