Niall,

how so? "_disable_logging" doesn't equal "immediate data loss"...so how so?
Do you mean if you do not UN-set it at after the task (load) is complete?

>> (well actually improves the likelihood of making a

I agree 100%

nope. you can always end up losing your database with this set, you better recognise it. time pressure is irrelevant (well actually improves the likelihood of making a simple error and losing the db yourself) _disable_logging would be better renamed _I_REALLY_REALLY_REALLY_DONT_CARE_ABOUT_THIS_DATA. If you set it, that is what you mean.

oh, and importing for a presentation, what a weird pressure on a database.
