Hi,
this is for the oracle baseheads out there:
Whenever you set up a database-instance in Oracle it's a good practice
to create an own user for it. Let's say for the Airline-Sample you will
create the user airline. Like this:
create user airline identified by airline;
grant resource, connect, create public synonym, drop public synonym to
airline;
grant create role, alter any role, drop any role, grant any role to airline;
grant create user, alter user, drop user to airline;
grant create snapshot to airline;
With sqlplus can query the existing tables without the schema-prefix.
Run ant create-tables with the user airline.
Whether or not you have put schema=${database.schema} in the
sample-build file Middlegen tries to create Java-Files with the
Schema-Prefix (The table is named airline.persons instead of Persons for
example). The table columns won't be recognized either. You can work
around the former by editing the fields base-class-name in
src/airline.prefs. But you can't create useful Beans without the latter
case.
Thus, I would propose the following patch. It prohibits the reporting of
the oracle schema whenever a oracle database is used.
The drawback of this solution (workaround?) is that you must explicit
name the tables in the sample build-file.
I just posted this topic here to get to know if this patch is reasonable
or if there is a better solution. If it's reasonable I will submit the
patch at sf.
Cheers,
Matthias
