[SQLObject] SQLObject delete queries

[Dave P. <dpo...@te...>]

How could one proceed to delete multiple records out of a database with
a single query?  I've been trying various methods but I seem to always
end up with an "unhashable" error.

desired query: DELETE * FROM accounts WHERE record_expiration <= NOW();

attempted SQLObject code:

Accounts.delete( (Accounts.q.record_expiration <= func.NOW()) )

the only way I've been able to delete the records was true a rather more
db intensive method:

for account in Accounts.select( (Accounts.q.record_expiration <=
func.NOW()) ):
  Accounts.delete( account.id )

Is there any better way to delete multiple rows?

Thanks in advance,
Dave.
