Bonjour,
Le rollback d'une requête alter table ne fonctionne pas pour le code suivant, par contre le rollback des requêtes insert fonctionne. J'utilise une base de données HSQLDB.

.createSQLQuery("alter table IO_MODULES add COLUMN CH_ADDR_GENERATORS varbinary(255)");
updateQuery.executeUpdate();
// this call will insert data in the new created column
setChannelsAdressGenerator4AllModules();
}
return uniqueResult;
}
});
}
private void setChannelsAdressGenerator4AllModules() {
// this method make inserts in database and use HibernateTemplate
......
// an error occurs here, and logically the alter table query in the previous code must be rollbacked
}
