Well,
as „drop-and-create-tables” will delete the
stored data this is not an option.
A complete check of the entities vs. the tables would be fine for
me. A warning/error should only be generated if there are differences.
Assuming that entities are stable and are equal to the already
created tables, a user/admin of our application will always see and be worried
about these warnings in the log.
I know that this warning is absolutely not critical, but others
will not. I guess the implementation is just a little slack and could be
improved.
Bye,
Daniel

Hi,
Then what about changes to your domain objects (entities) ? A simple check is
not enough, it should compare each property.
Can't you just use this; <property
name="eclipselink.ddl-generation"
value="drop-and-create-tables"/>

Hi all,
In my persistence.xml I'm using eclipselink.ddl-generation=create-tables
If my application is started the 2nd time, the tables do already exist
(of course).
This leads to the following warning:
[EL Warning]: 2009.02.18
09:21:33.154--ServerSession(27887470)--Exception [EclipseLink-4002]
(Eclipse Persistence Services - 1.0.2 (Build 20
081024)): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: SQL Exception: Table/View 'RECORDS' already exists
in Schema 'SMILA'.
Error Code: 30000
Call: CREATE TABLE RECORDS (ID VARCHAR(1024) NOT NULL, SOURCE
VARCHAR(1024), RECORD BLOB, PRIMARY KEY (ID))
In my opinion there should not be a warning at all. Instead of executing
the create table SQL statement it should be checked if the table already
exists and only execute the SQL if it does not.
Is it possible to somehow suppress this warning ? Changing the log level
is not what I'm looking for :-)
Bye,
Daniel
