I'm trying to find a way to tell Hibernate "whenever you create this table, insert these rows immediately afterwards"
Since Hibernate 3.1, you can include a file called import.sql
in the runtime classpath of Hibernate and at the time of schema export, Hibernate will execute the SQL statements contained in that file after the schema has been exported.
This feature has been announced in the Rotterdam JBug and Hibernate's import.sql blog post:
Hibernate has a neat little feature
that is heavily under-documented and
unknown. You can execute an SQL script
during the SessionFactory
creation
right after the database schema
generation to import data in a fresh
database. You just need to add a file
named import.sql
in your classpath
root and set either create
or
create-drop
as your
hibernate.hbm2ddl.auto
property.
I use it for Hibernate Search in
Action now that I have started the
query chapter. It initializes my
database with a fresh set of data for
my unit tests. JBoss Seam also uses it
a lot in the various examples.
import.sql
is a very simple feature
but is quite useful at time. Remember
that the SQL might be dependent on
your database (ah portability!).
#import.sql file
delete from PRODUCTS
insert into PRODUCTS (PROD_ID, ASIN, TITLE, PRICE, IMAGE_URL, DESCRIPTION) values ('1', '630522577X', 'My Fair Lady', 19.98, '630522577X.jpg', 'My Fair blah blah...');
insert into PRODUCTS (PROD_ID, ASIN, TITLE, PRICE, IMAGE_URL, DESCRIPTION) values ('2', 'B00003CXCD', 'Roman Holiday ', 12.98, 'B00003CXCD.jpg', 'We could argue that blah blah');
For more information about this
feature, check Eyal's blog, he
wrote a nice little entry about it.
Remember if you want to add additional
database objects (indexes, tables and
so on), you can also use the auxiliary
database objects feature.
It is still not really documented.
