You are right.
This is the way I solved it.
public class DInAdminEOModel17 implements IERXMigration {
public NSArray<ERXModelVersion> modelDependencies() {
return null;
}
public void upgrade(EOEditingContext editingContext,
EOAdaptorChannel channel, EOModel model) throws
Throwable {
ERXJDBCUtilities.executeUpdateScriptFromResourceNamed(channel,
"Migrations/DInAdminEOModel17_Upgrade.sql", null);
ERXJDBCUtilities.fetchRowSet(channel, "SELECT
inserta_empresa_pacs() ;");
ERXJDBCUtilities.executeUpdate(channel, "DROP FUNCTION
inserta_empresa_pacs();");
}
public void downgrade(EOEditingContext editingContext,
EOAdaptorChannel channel, EOModel model) throws
Throwable {
// whatever it takes to invert those
}
}
I guess it would be better to split it into several migrations but it is a
controlled change so it works for me.
Thanks.
Miguel Torres.
