That's right but I've to write a script which don't know what type of DBMS is installed so...
it prompt to ask for:
  - a DBMS server, port, user, pass
- the path of the ODBC library used to connect

then it tries to create the DSN but DB are not included in templates so...
may I have to also ask for the default database?
I'd like to make my tests into an ad-hoc created database...
F.E. see: http://www.firebirdsql.org/manual/qsg10-creating.html

I want to know if it is possible using unixODBC:
- get a list of existing database making a query to the DBMS using it's ODBC library.
or
- (better) create a DB and then connect to it

For this operation should be sufficient to know:
- which odbc driver to use 
- server:port
- user
- password
Is this true? I really don't know, what do you think?
thank you,
carlo cancellieri
