Can I safely CTRL-ALT-DEL EA without damaging my model?

[Richard Freggi]

I have a query with a seriously messed up join condition (result of a botched copy-paste job) on t_object on a large model (many thousands of elements).
The database is local to my PC and is Firebird
The query has been running for 30 minutes, I'm tempted to just shutdown the application reasoning that this is DML so should not corrupt the database file (OF COURSE I have not backed up in a couple of days!)

Can anyone advise if just pulling the plug is safe?  Or better to just wait it out for a few hours?  Thanks!!!
- p.s. the query finally completed after about 40 minutes, everything seems OK, but I still would like to know if CTRL-ALT-DEL during a query is safe to do!  Thanks!

Yes, it's "rather" safe. A query alone can't damage anything. Updates only if you hit them at the wrong spot. There's the "repair Access" option. And of course: You have backups, don't you?
